Warnings for Configuring Drive Parameters
WARNING: When parameter B_12, level of electronic thermal setting, is set to device FLA rating (Full Load Ampere nameplate rating), the device provides solid state motor overload protection at 115% of device FLA or equivalent. Parameter B_12, level of electronic thermal setting, is a variable parameter. WARNING: Use a disconnect switch or breaker to ensure that you do not connect the motor or inverter to live wiring. Otherwise, there is the danger of electric shock. 324
Cautions for Configuring Drive Parameters
CAUTION: Be careful to avoid specifying a braking time that is long enough to cause motor overheating. If you use DC braking, we recommend using a motor with a built-in thermistor, and wiring it to the inverters thermistor input (see Thermistor Thermal Protection on page 420). Also refer to the motor manufacturers specifications for duty-cycle recommendations during DC braking. 315
Warnings for Operations and Monitoring
WARNING: Be sure to turn ON the input power supply only after closing the front case. While being energized, be sure not to open the front case. Otherwise, there is the danger of electric shock. WARNING: Be sure not to operate electrical equipment with wet hands. Otherwise, there is the danger of electric shock. WARNING: While the inverter is energized, be sure not to touch the inverter terminals even when the motor is stopped. Otherwise, there is the danger of electric shock. WARNING: If the Retry Mode is selected, the motor may suddenly restart after a trip stop. Be sure to stop the inverter before approaching the machine (be sure to design the machine so that safety for personnel is secure even if it restarts.) Otherwise, it may cause injury to personnel. WARNING: If the power supply is cut OFF for a short period of time, the inverter may restart operation after the power supply recovers if the Run command is active. If a restart may pose danger to personnel, so be sure to use a lock-out circuit so that it will not restart after power recovery. Otherwise, it may cause injury to personnel. WARNING: The Stop Key is effective only when the Stop function is enabled. Be sure to enable the Stop Key separately from the emergency stop. Otherwise, it may cause injury to personnel. 43

Operator Interface Options
The optional SRW-0EX digital operator / copy unit is shown to the right. It has the additional capability of reading (uploading) the parameter settings in the inverter into its memory. Then you can connect the copy unit on another inverter and write (download) the parameter settings into that inverter. OEMs will find this unit particularly useful, as one can use a single copy unit to transfer parameter settings from one inverter to many. Other digital operator interfaces may be available from your Hitachi distributor for particular industries or international markets. Contact your Hitachi distributor for further details.

Derating Curves

The maximum available inverter current output is limited by the carrier frequency and ambient temperature. The carrier frequency is the inverters internal power switching frequency, settable from 0.5 kHz to 16 kHz. Choosing a higher carrier frequency tends to decrease audible noise, but it also increases the internal heating of the inverter, thus decreasing (derating) the maximum current output capability. Ambient temperature is the temperature just outside the inverter housingsuch as inside the control cabinet where the inverter is mounted. A higher ambient temperature decreases (derates) the inverters maximum current output capacity. Use the following derating curves to help determine the optimal carrier frequency setting for your inverter, and to find the output current derating. Be sure to use the proper curve for your particular L100 inverter model number.

Intelligent Functions and Parameters
Much of this manual is devoted to describing how to use inverter functions and how to configure inverter parameters. The inverter is microprocessor-controlled, and has many independent functions. The microprocessor has an on-board EEPROM for parameter storage. The inverters front panel keypad provides access to all functions and parameters, which you can access through other devices as well. The general name for all these devices is the digital operator, or digital operator panel. Chapter 2 will show you how to get a motor running, using a minimal set of function commands or configuring parameters. The optional read/write programmer will let you read and write inverter EEPROM contents from the programmer. This feature is particularly useful for OEMs who need to duplicate a particular inverters settings in many other inverters in assembly-line fashion.

Braking

In general, braking is a force that attempts to slow or stop motor rotation. So it is associated with motor deceleration, but may also occur even when the load attempts to drive the motor faster than the desired speed (overhauling). If you need the motor and load to decelerate quicker than their natural deceleration during coasting, we recommend installing an optional dynamic braking unit. See Introduction on page 52 and Dynamic Braking on page 55 for more information on the BRDE2 and BRDEZ2 braking units. The L100 inverter sends excess motor energy into a resistor in the dynamic braking unit to slow the motor and load. For loads that continuously overhaul the motor for extended periods of time, the L100 may not be suitable (contact your Hitachi distributor). The inverter parameters include acceleration and deceleration, which you can set to match the needs of the application. For a particular inverter, motor, and load, there will be a range of practically achievable accelerations and decelerations.

Velocity Profiles

The L100 inverter is capable of sophisticated speed control. A graphical representation of Speed that capability will help you understand and configure the associated parameters. This manual makes use of the velocity profile 0 graph used in industry (shown at right). In the example, acceleration is a ramp to a set speed, and deceleration is a decline to a stop.

Set speed Accel Decel t

Velocity Profile
Acceleration and deceleration settings specify Speed Maximum speed the time required to go from a stop to maximum frequency (or visa versa). The resulting slope (speed change divided by time) is the acceleration or deceleration. An increase in output frequency uses the acceleration 0 slope, while a decrease uses the deceleration t Acceleration slope. The accel or decel time a particular (time setting) speed change depends on the starting and ending frequencies. However, the slope is constant, corresponding to the full-scale accel or decel time setting. For example, the full-scale acceleration setting (time) may be 10 secondsthe time required to go from 0 to 60 Hz. The L100 inverter can store up to 16 preset speeds. And, it can apply separate acceleration Speed Speed 2 and deceleration transitions from any preset to Speed 1 any other preset speed. A multi-speed profile (shown at right) uses two or more preset 0 speeds, which you can select via intelligent t input terminals. This external control can Multi-speed Profile apply any preset speed at any time. Alternatively, the selected speed is infinitely variable across the speed range. You can use the potentiometer control on the keypad for manual control. The drive accepts analog 0-10V signals and 4-20 mA control signals as well. The inverter can drive the motor in either Speed direction. Separate FW and RV commands select the direction of rotation. The motion 0 profile example shows a forward motion followed by a reverse motion of shorter duration. The speed presets and analog signals control the magnitude of the speed, while the FWD and REV commands determine the direction before the motion starts.

A molded-case circuit breaker (MCCB), ground fault interrupter (GFI), or a fused disconnect device. NOTE: The installer must refer to the NEC and local codes to ensure safety and compliance. This is useful in suppressing harmonics induced on the power supply lines and for improving the power factor. WARNING: Some applications must use an inputside AC reactor to prevent inverter damage. See Warning on next page.

This capacitive filter reduces radiated noise from the main power wires in the inverter input side. Suppresses harmonics generated by the inverter. However, it will not protect the input diode bridge rectifier. This is useful for increasing the inverters control torque for high duty-cycle (ON-OFF) applications, and improving the decelerating capability.

NOTE: Note that some components are required for regulatory agency compliance (see Chapter 5 and Appendix C).
Step-by-Step Basic Installation
WARNING: In the cases below involving a general-purpose inverter, a large peak current can flow on the power supply side, sometimes destroying the converter module: 1.The unbalance factor of the power supply is 3% or higher. 2.The power supply capacity is at least 10 times greater than the inverter capacity (or the power supply capacity is 500 kVA or more). 3.Abrupt power supply changes are expected, due to conditions such as: a. Several inverters are interconnected with a short bus. b. A thyristor converter and an inverter are interconnected with a short bus. c. An installed phase advance capacitor opens and closes.

Ensure Adequate Ventilation
2 Step 2: To summarize the caution messagesyou will need to find a solid, non-flammable, vertical surface that is in a relatively clean and dry environment. In order to ensure enough room for air circulation around the inverter to aid in cooling, maintain the specified clearance around the inverter specified in the diagram.

Clear area

10 cm (3.94) minimum

Air flow

8 cm (3.15) minimum

12 cm (4.72) minimum

CAUTION: Be sure to maintain the specified clearance area around the inverter and to provide adequate ventilation. Otherwise, the inverter may overheat and cause equipment damage or fire.
Keep Debris Out of Inverter Vents
3 Step 3: Before proceeding to the wiring section, its a good time to temporarily cover the inverters ventilation openings. Paper and masking tape are all that is needed. This will prevent harmful debris such as wire clippings and metal shavings from entering the inverter during installation. The inverter housing comes from the factory with a snap-in cover on the top of its housing. Ensure it is in place at this time (also to be removed later, unless the installation must have a NEMA rating). Please observe this checklist while mounting the inverter:

Top cover installed

Ventilation holes (both sides)
1. The ambient temperature must be in the range of -10 to 40C. If the range will be up to 50C, you will need to set the carrier frequency to 2.1 kHz or less and derate the output current to 80% or less. Chapter 3 covers how to change parameters such as the carrier frequency. Remember to remove the top cover (unless the installation is to have a NEMA rating)! 2. Keep any other heat-producing equipment as far away from the inverter as possible.
L100 Inverter 3. When installing the inverter in an enclosure, maintain the clearance around the inverter and verify that its ambient temperature is within specification when the enclosure door is closed. 4. Do not open the main front panel door at any time during operation.

Keys, Modes, and Parameters
Purpose of the keypad is to provide a way to change modes and parameters. The term function applies to both monitoring modes and parameters. These are all accessible through function codes that are primarily 3-character codes. The various functions are separated into related groups identifiable by the left-most character, as the table shows.
Function Group D F A B C E Type (Category) of Function Monitoring functions Main profile parameters Standard functions Fine tuning functions Intelligent terminal functions Error codes Mode to Access Monitor Program Program Program Program PGM LED Indicator
For example, function A_04 is the base frequency setting for the motor, typically 50 Hz or 60 Hz. To edit the parameter, the inverter must be in Program Mode (PGM LED will be ON). You use the front panel keys to first select the function code A_04. After displaying the value for A_04, use the Up/Down ( 1 or 2 ) keys to edit it. NOTE: The inverter 7-segment display shows lower case b and d, meaning the same as the upper case letters B and D used in this manual (for uniformity A to F). The inverter automatically switches into Monitor MONITOR PROGRAM Mode when you access D Group functions. It A Group switches into Program Mode when you access any B Group D Group other group, because they all have editable paramC Group F Group eters. Error codes use the E Group, and appear automatically when a fault event occurs. Refer to Monitoring Trip Events, History, & Conditions on page 65 for error code details.

Keypad Navigational Map

The L100 Series inverter drives have many programmable functions and parameters. Chapter 3 will cover these in detail, but you need to access just a few items to perform the powerup test. The menu structure makes use of function codes and parameter codes to allow programming and monitoring with only a 4-digit display and a few keys and LEDs. So, it is important to become familiar with the basic navigational map of parameters and functions in the diagram below. You may later use this map as a reference. Monitor Mode PRG LED=OFF Display Data Program Mode PRG LED=ON

Overload Restriction

If the inverters output current exceeds a preset current level you specify during acceleration or constant speed, the overload restriction feature automatically reduces the output frequency to restrict the overload. This feature does not generate an alarm or trip event. You can instruct the inverter to apply overload restriction only during constant speed, thus allowing higher currents for acceleration. Or, you may use the same threshold for both acceleration and constant speed. In the case of controlled deceleration, the inverter monitors both output current and DC bus voltage. The inverter will increase output frequency to try to avoid a trip due to over-current or over-voltage (due to regeneration).
Motor Current B t Output frequency 0 B 23 Restriction area
When the inverter detects an overload, it must decelerate the motor to reduce the current until it is less than the threshold. You can choose the rate of deceleration that the inverter uses to lower the output current.

The software lock function keeps personnel from accidentally changing parameters in the inverter memory. Use B_31 to select from various protection levels. The table below lists all combinations of B_31 option codes and Run the ON/OFF state of the [SFT] input. Each Check or Ex Mode indicates whether the corresponding parameter(s) can be edited. Edit The Standard Parameters column below shows access is permit ted for some lock modes. These refer to the parameter tables throughout this chapter, each of which includes a column titled Run Mode Edit as shown to the right. The marks (Check or Ex ) under the Run Mode Edit column title indicate whether access applies to each parameter as defined in the table below. In some lock modes, you can edit only F_01 and the Multi-speed parameter group that includes A_20, A220, A_21A_35, and A_38 (Jog). However, it does not include A_19, Multi-speed operation selection. The editing access to B_31 itself is unique, and is specified in the right-most two columns below.

Connecting to PLCs and Other Devices
Hitachi inverters (drives) are useful in many types of applications. During installation, the inverter keypad (or other programming device) will facilitate the initial configuration. After installation, the inverter will generally receive its control commands through the control logic connector or serial interface from another controlling device. In a simple application such as single-conveyor speed control, a Run/Stop switch and potentiometer will give the operator all the required control. In a sophisticated application, you may have a programmable logic controller (PLC) as the system controller, with several connections to the inverter. It is not possible to cover all the possible types of application in this manual. It will be necessary for you to know the electrical characteristics of the devices you want to connect to the inverter. Then, this section and the following sections on I/O terminal functions can help you quickly and safely connect those devices to the inverter. CAUTION: It is possible to damage the inverter or other devices if your application exceeds the maximum current or voltage characteristics of a connection point. The connections between the inverter and other devices rely on the electrical input/ output characteristics at both ends of each connection, shown in the diagram to the right. The inverters inputs require a sourcing output from an external device (such as a PLC). This chapter shows the inverters internal electrical component(s) at each I/O terminal. In some cases, you will need to insert a power source in the interface wiring. In order to avoid equipment damage and get your application running smoothly, we recommend drawing a schematic of each connection between the inverter and the other device. Include the internal components of each device in the schematic, so that it makes a complete circuit loop. After making the schematic, then: 1. Verify that the current and voltage for each connection is within the operating limits of each device.

2. Make sure that the logic sense (active high or active low) of any ON/OFF connection is correct. 3. Check the zero and span (curve end points) for analog connections, and be sure the scale factor from input to output is correct. 4. Understand what will happen at the system level if any particular device suddenly loses power, or powers up after other devices.

Example Wiring Diagram

The schematic diagram below provides a general example of logic connector wiring, in addition to basic power and motor wiring covered in Chapter 2. The goal of this chapter is to help you determine the proper connections for the various terminals shown below for your specific application needs.

See I/O specs on page 46.
NOTE: The parameter F_04, Keypad Run Key Routing, determines whether the single Run key issues a Run FWD command or Run REV command. However, it has no effect on the [FW] and [RV] input terminal operation.
WARNING: If the power is turned ON and the Run command is already active, the motor starts rotation and is dangerous! Before turning power ON, confirm that the Run command is not active.

Multi-Speed Select

The inverter can store up to 16 different target frequencies (speeds) that the motor output uses for steady-state run condition. These speeds are accessible through programming four of the intelligent terminals as binary-encoded inputs CF1 to CF4 per the table to the right. These can be any of the five inputs, and in any order. You can use fewer inputs if you need eight or fewer speeds. Note: When choosing a subset of speeds to use, always start at the top of the table, and with the least-significant bit: CF1, CF2, etc. The example with eight speeds in the figure below shows how input switches configured for CF1 CF3 functions can change the motor speed in real time.

Frequently Asked Questions
What is sensorless vector control? Sensorless vector control is a technique used in variable frequency drives to rotate the force vector in the motor without the use of a shaft position sensor. The goal of AC sensorless vector technology is to give the user DC like control while making traditional speed or shaft position feedback from the motor unnecessary. The SV control removes a major source of complexity and potential for failure (the tach. feedback), while simplifying many AC drive installations. How do I connect a resistor (SRB) to an inverter drive? Connect the resistor leads to + and RB. There are also a set of overtemperature contact terminals on the resistor which should be wired to an intelligent input allocated for trip purpose. It would also be appropriate to wire any emergency stop contacts in series with this overtemperature contact. How does Hz correlate to speed on an inverter drive? Motor base speed divided by 60 Hz = RPM/Hz. Example; 1200RPM divided by 60 = 20 rpm/Hz. This information is useful for scaling the inverter display to display rpm's instead of Hz. Simply place the above result into B86 and then choose D07 to display. The display will read rpm. Do I need to purchase anything else to program my drive? No, you can program the drives from the front panel using the function keys and by using the appropriate parameters located in the manual. What is the duty cycle? The duty cycle is the percent of time a device is on vs. off. It can be the ratio of operating time of a motor to its resting time. This parameter usually is specified in association with the allowable thermal rise for the device. Can the software be used with Allen-Bradley equipment? No, the DOP software cannot be used with the Allen-Bradley equipment due to the function blocks capability of the AllenBradley equipment. Can I use a separate power supply for my drive? Yes, you can use an external 24Vdc power supply to source the voltage for your intelligent input terminals. You will need to connect the common on the remote power supply to the drive's L terminal. However, do not connect the + terminal of the internal supply to the external one. I cannot get my intelligent terminal to program with the options I want. It just skips over them. Why? If the option you wish to use is the default of a different terminal the inverter will not let you program it in two places. You will need to use it at its default location or change it so that you do not have it in two places. Also, if the drive is in Run, items such as Intelligent Terminal Allocation cannot be changed due to safety reasons. Can I use the 24vdc supply on the inverter for field devices on my machine? The 24VDC supply on the inverter is for the operation of control terminals and is not recommended for use with other devices. Will the SJ100 accept encoder feedback? No, the SJ-100 will not accept encoder feedback. It is a micro drive and does not have the option card, and therefore no encoder feedback. When I connect the remote operator it gets a Comm 2 error. The cable and connector check out ok, but the error will not go away. Why? Open the small cover on the back of the unit and check dip switches 1 and 2. Switch 1 should be off and switch 2 should be on. We are building a panel for our drives. How can we know the heat put out by each drive? The watt loss chart shows the amount of heat generated by the drive at 70 and 100 percent load of drive. The units are given in watts lost. What is the main advantage in using an inverter to drive a motor, compared to alternative solutions? An inverter can vary the motor speed with very little loss of efficiency, unlike mechanical or hydraulic speed control solutions. The resulting energy savings usually pays for the inverter in a relatively short time. Although the SJ100 inverter is a variable speed drive, can I use it in a fixed-speed application? A fixed speed application usually is a result of cost-sensitivity or negligible benefits if variable speed were used (consumer products are examples). In those cases, the power source connects directly to the motor (no special drive needed). However, using a variable speed drive can benefit many type of industrial and commercial motor applications, by providing controlled acceleration and deceleration, high torque at low speeds, and energy savings over alternative solutions.

The term inverter is a little confusing, since we also use drive and amplifier to describe the electronic unit that controls a motor. What does inverter mean? The terms inverter, drive, and amplifier are used somewhat interchangeably in industry. But there are subtle differences. A drive can refer to the motor, the control electronics, or both. This term is used particularly when the motor and electronics are integrated in the same housing. The term variable speed drive can include many types of devices such as anything that has a variable speed output, which includes the Hitachi inverter. Amplifier more commonly refers to a linear amplifier for servo motor control, or a stepper motor driver IC. Finally, we use inverter to describe the Hitachi motor controller because of the way the switching electronics alternately inverts or directly couples its internal DC voltage bus to generate a variable AC output. Can I use an inverter and AC induction motor in a positioning application? That depends on the required precision, and the slowest speed the motor will must turn and still deliver torque. The SJ100 inverter will deliver full torque while turning the motor at only 0.5 Hz (15 RPM). DO NOT use an inverter if you need the motor to stop and hold the load position without the aid of a mechanical brake (use a servo or stepper motion control system). Does the optional digital operator interface or the PC software (DOP Plus) provide features beyond what is available from the keypad on the unit? Yes. However, note first that the same set of parameters and functions are equally accessible from either the unit's keypad or from remote devices. The DOP Plus PC software lets you save or load inverter configurations to or from a disk file. And, the hand-held digital operator provides hardwired terminals, a safety requirement for some installations. Why does the manual or other documentation use terminology such as 200V class instead of naming the actual voltage, such as 230 VAC? A specific inverter model is set at the factory to work across a voltage range particular to the destination country for that model. The model specifications are on the label on the side of the inverter. A European 200V class inverter (EU marking) has different parameter settings than a USA 200V class inverter (US marking). The initialization procedure can set up the inverter for European or US commercial voltage ranges. Why is there not a 100V class version of the SJ100 inverter, so it would work with a USA 115VAC power source, for example? Most industrial, commercial, or heavy appliance applications use 230VAC in the USA. Also, a builtin advantage is that using the higher voltage means less current to deliver the same amount of power. This allows you to use smaller diameter (and less expensive) wire for power and motor wiring. I live in a country where the domestic utility power is 115 VAC. Is there a way to conveniently access a 230 VAC power source for a test bench to develop a motor application? A 1:2 step-up transformer is available from a number of sources (check your local electrical supply house). The transformer will be designed to develop 230 VAC from 115 VAC, for example. Be sure the power output rating (kW) of the transformer is greater than 1.73 times the three-phase current of the motor you intend to power. We recommend doing this for motors 1/2 horse-power or smaller, with small loads. For 400 V class inverters, we recommend only using a utility power source of the correct voltage. Some models of Hitachi inverters will accept either single phase or three-phase power input. How do I know which input power type to use? If three-phase power is conveniently available for your application, we recommend using that (the inverter can develop its threephase output power most efficiently from three-phase input power). In the absence of threephase power, you can use a single-phase power source with slightly less efficiency but the power output rating is the same for N models (single or threephase). If I decide to use single-phase input power for the inverter, can I also use a single-phase motor? No. All Hitachi inverters develop a variable three-phase output, requiring the use of a three-phase AC induction motor. Why doesn't the motor have a neutral connection as a return to the inverter? The motor theoretically represents a balanced Y load if all three stator windings have the same impedance. The Y connection allows each of the three wires to alternately serve as input or return on alternate half-cycles.

Does the motor need a chassis ground connection? Yes, for several reasons. This is for protection in the event of a short in the motor that puts a live voltage on its housing. Motors and other components exhibit leakage currents that increase with aging. And, a grounded chassis generally emits less electrical noise than an ungrounded one. What type of motor is compatible with the Hitachi inverters? Motor type it must be a three phase AC induction motor. Use an inverter-grade motor that has 800V insulation for 200V class inverters, or 1600V insulation for 400V class. Motor size In practice, it's better to find the right size motor for your application, then look for the inverter to match the motor. How many poles should the motor have? Using a four-pole motor will work for most applications. Hitachi inverters can be configured to operate motors with 2, 4, 6, or 8 poles. The greater the number of poles, the slower the top motor speed will be, but it will have higher torque at the slowest speed. Will I be able to add dynamic (resistive) braking to my Hitachi SJ100 drive after the initial installation? Yes. The SJ100 inverter already has a dynamic braking circuit built in. Just add the resistor sized to meet the braking requirements. How will I know if my application will require resistive braking? For new applications, it may be difficult to tell before you actually test a motor/drive solution. In general, some applications can rely on system losses such as friction to serve as the decelerating force, or otherwise can tolerate a long decel time. These applications will not need dynamic braking. However, applications with a combination of a highinertia load and a required short decel time will need dynamic braking. This is a physics question that may be answered either empirically or through extensive calculations. Several options related to electrical noise suppression are available for the Hitachi inverters. How can I know if my application will require any of these options? The purpose of these noise filters is to reduce the inverter electrical noise so the operation of nearby electrical devices is not affected. Some applications are governed by particular regulatory agencies, and noise suppression is mandatory. In those cases, the inverter must have the corresponding noise filter installed. Other applications may not need noise suppression, unless you notice electrical interference with the operation of other devices. The SJ100 features a PID loop feature. PID loops are usually associated with chemical processes, heating, or process industries in general. How could the PID loop feature be useful in my application? You will need to determine which main variable in your application the motor affects. That is the process variable (PV) for the motor. Over time, a faster motor speed will cause a faster change in the PV than a slow motor speed will. By using the PID loop feature, the inverter commands the motor to run at the optimal speed required to maintain the PV at the desired value for current conditions. Using the PID loop feature will require an additional sensor and other wiring, and is considered an advanced application. Is it possible to use three phase drives with single phase input? Can you use larger drives with derating to run something like a 5hp motor with a 10 hp drive on single phase? Generally, this is possible, but doubling the drive hp capacity is not necessarily sufficient. There are several concerns: 1) Higher motor current for single vs. 3 phase - this is about double (x 1.732 to be exact, but double for selection purposes). You must also account for peak motor current (application dependent), and select the proper drive size based on its output current capacity, rather than hp rating. 2) The fact that one input phase is missing means that part of the input bridge is carrying higher current than it normally would. You must make sure that the input current does not exceed the rating of the drive. 3) Since we are only rectifying single phase, the harmonic content is higher, and different in frequency composition. This means that an input line reactor is a definite requirement. Also this impacts on the DC Link, and the higher harmonic content may adversely affect the life expectancy of the DC Link capacitors. There is no easy way to calculate this, but if the drive is sized adequately, this is not a major issue.
