Do not Use a Phase Advancing Capacitor or Noise Filter Do not Use an Electromagnetic Switch of Magnetic Contactor
Installing a Thermal Relay
Installing a Noise Filter on the Output Side
Connect a Noise Filter to the output side of the Inverter to reduce radio noise and induction noise.
Power supply MCCB CIMR-J7AZ VARISPEED Noise Filter
Induction noise Radio noise Controller AM radio
Induction Noise: Electromagnetic induction generates noise on the signal line, causing the controller to malfunction. Radio Noise: Electromagnetic waves from the Inverter and cables cause the broadcasting radio receiver to make noise.
Countermeasures against Induction Noise
As described previously, a Noise Filter can be used to prevent induction noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent induction noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces induction noise.
MCCB CIMR-J7AZ VARISPEED Metal pipe
30 cm min. Signal line Controller
Countermeasures against Radio Interference
Radio noise is generated from the Inverter as well as the input and output lines. To reduce radio noise, install Noise Filters on both input and output sides, and also install the Inverter in a totally enclosed steel box. The cable between the Inverter and the motor should be as short as possible.
MCCB Noise Filter
CIMR-J7AZ Noise Filter
Cable Length between Inverter and Motor
As the cable length between the Inverter and the motor is increased, the floating capacity between the Inverter outputs and the ground is increased proportionally. The increase in floating capacity at the Inverter outputs causes the high-frequency leakage current to increase, and this may adversely affect peripheral devices and the current detector in the Inverters output section. To prevent this from occurring, use a cable of no more than 100 meters between the Inverter and the motor. If the cable must be longer than 100 meters, take measures to reduce the floating capacity by not wiring in metallic ducts, by using separate cables for each phase, etc. Also, adjust the carrier frequency (set in n46) according to the cable length between the Inverter and the motor, as shown in the following table.
Cable length 50 m or less Carrier frequency 10 kHz max. 100 m or less 5 kHz max. More than 100 m 2.5 kHz
Single-phase motors cannot be used. The Inverter is not suited for the variable speed control of single-phase motors. The rotation direction of a single-phase motor is determined by the capacitor starting method or phase-splitting starting method to be applied when starting the motor. In the capacitor starting method, however, the capacitor may be damaged by a sudden electric discharge of the capacitor caused by the output of the Inverter. On the other hand, the starting coil may burn in the phase-splitting starting method because the centrifugal switch does not operate.
Wiring Ground Wiring
Always use the ground terminal with the following ground resistance: 200-V Inverter: 100 W or less 400-V Inverter: separate ground,10 W or less Do not share the ground wire with other devices such as welding machines or power tools. Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire. Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the ground terminal is too long, the potential on the ground terminal of the Inverter will become unstable. When using more than one Inverter, be careful not to loop the ground wire.
Harmonics consist of electric power produced from AC power and alternating at frequencies that are integral multiples of the frequency of the AC power. The following frequencies are harmonics of a 60- or 50-Hz commercial power supply. Second harmonic: 120 (100) Hz Third harmonic: 180 (150) Hz
Second harmonic (120 Hz) Basic frequency (60 Hz)
Third harmonic (180 Hz)
Problems Caused by Harmonics Generation The waveform of the commercial power supply will be distorted if the commercial power supply contains excessive harmonics. Machines with such a commercial power supply will malfunction or generate excessive heat.
Basic frequency (60 Hz) Third harmonic (180 Hz)
Distorted current wave form
Causes of Harmonics Generation
Usually, electric machines have built-in circuitry that converts commercial AC power supply into DC power. Such AC power, however, contains harmonics due to the difference in current flow between DC and AC. Obtaining DC from AC Using Rectifiers and Capacitors DC voltage is obtained by converting AC voltage into a pulsating one-side voltage with rectifiers and smoothing the pulsating one-side voltage with capacitors. Such AC current, however, contains harmonics. Inverter The Inverter as well as normal electric machines has an input current containing harmonics because the Inverter converts AC into DC. The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine.

1. Local or remote selection is possible only when the Inverter is not in operation. The present setting can be monitored when the Inverter is in operation. 2. Local or remote settings in multi-function input terminals can be changed through the multifunction input terminals only. 3. Any RUN command input will be ignored while the LO/RE indicator is lit. To enable a RUN command, first turn the RUN command OFF and then press the Mode Key to display an item that has a green indicator (FREF to MNTR). Then input the RUN command again.
Adjusting the Analog Input
Input characteristic adjustments may be necessary for analog frequency references to be input. At that time, use the following parameters for gain, bias, and filter time parameter adjustments.
FR Terminal Adjustments for Frequency Reference Input
Gain and Bias Settings (n41 and n42) Set the input characteristics of analog frequency references in n41 (for the frequency reference gain) and n42 (for the frequency reference bias). Set the frequency of maximum analog input (10 V or 20 mA) in n41 as percentage based on the maximum frequency as 100%. Set the frequency of minimum analog input (0 V, 0 mA, or 4 mA) in n42 as percentage based on the maximum frequency as 100%.
n41 Setting range n42 Setting range Frequency Reference Gain 0% to 255% (Max. frequency = 100%) Unit of setting 1% Changes during operation Default setting Yes 100
Frequency Reference Bias -99% to 99% (Max. frequency = 100%) Unit of setting 1%
Changes during operation Default setting 0
Analog Frequency Reference Filter Time (n43) The digital filter with a first-order lag can be set for analog frequency references to be input. This setting is ideal if the analog input signal changes rapidly or the signal is subject to noise interference. The larger the set value is, the slower the response speed will be.

Analog Monitor Output
5-10 Analog Monitor Output
The J7AZ incorporates analog monitor output terminals AM and AC. These terminals have analog monitor values of output frequency or current.
Setting the Analog Monitor Output (n44 and n45)
The output frequency or current as a monitored item is set in n44. The analog output characteristics are set as an analog monitor output gain in n45.
n44 Setting range 0, 1 Analog Monitor Output Unit of setting 1 Changes during operation Default setting 0 No
Value n45 Setting range 0.00 to 2.00 Description Output frequency (Reference: 10 V at max. frequency) Output current (Reference: 10 V with rated output current) Analog Monitor Output Gain Unit of setting 0.01 Changes during operation Default setting Yes 1.00
1. Set the multiplication ratio based on the set value in n44. For example, if an output of 5 V is desired at maximum frequency (with n44 set to 0), set n45 to 0.50. 2. The maximum output voltage of the analog monitor output terminals are 10 V.

Setting the Carrier Frequency
This chapter provides information on the use of advanced functions of the Inverter for operation. Refer to this chapter to use the various advanced functions, such as stall prevention, carrier frequency setting, overtorque detection, torque compensation, and slip compensation.
The carrier frequency of the J7AZ can be fixed or varied in proportion to the output frequency.

Carrier Frequency Selection Unit of setting 1
DC Injection Braking Function
The DC injection braking function applies DC on the induction motor for braking control. Startup DC Injection Braking: This braking is used for stopping and starting the motor rotating by inertia with no regenerative processing. DC Injection Braking to Stop: Adjust the stop DC injection braking time if the motor rotating does not decelerate to a stop in normal operation due to inertia from a heavy load. By increasing the DC injection braking time or DC injection braking current, the time required for stopping the motor is reduced.

Set the DC injection braking current as percentage based on the rated current of the Inverter as 100%. After the startup DC injection braking time is set, the Inverter starts up at minimum frequency on completion of the startup DC injection braking control of the Inverter. After the speed is reduced, the Inverter is switched to DC injection braking at minimum output frequency.

Stall Prevention Function
A stall will occur if the motor cannot keep up with the rotating magnetic field on the motor stator side when a large load is applied to the motor or a sudden acceleration/deceleration is performed. In the J7AZ, stall prevention functions can be set independently for accelerating, running, and decelerating conditions.
n55 Setting range 0, 1
Stall Prevention Level during Deceleration Unit of setting 1
Value Stall prevention during deceleration Stall prevention during deceleration Description
If 1 is set, the motor will be decelerated according to the set deceleration time. If the deceleration time is too short, the main circuit may result in overvoltage. If 0 is set, the deceleration time will be automatically lengthened to prevent overvoltage.
The function code is a command giving instructions of the details of processing to the Inverter. The following three functions codes are available.
Function code 03 Hex 08 Hex 10 Hex
Command name Data read Loop-back test Data write
Description Reads the data of the specified register number. Consecutive data of a maximum of 16 words (32 bytes) can be read. The DSR message is returned as a response. This command is used for checking the status of communications. The attached data in the format is written to the specified register number. Consecutive data of a maximum of 16 words (32 bytes) can be written.
1. Do not use any code other than the above, otherwise the Inverter will detect a communications error and return an error message. 2. The Inverter uses the same function code for the response. If an error occurs, however, the MSB of the function code will be set to 1. For example, if an error occurs in a DSR message with function code 03, the function code of the response will be 83.
Communications data is attached to the command. The contents and its arrangement of communications data vary with the function code. For details, refer to 7-4 DSR Message and Response.
Message Communications Basic Format Error Check
The CRC-16 check code is the remainder (16 bits) when all of the message blocks from the Slave address to the final communications data are connected in series, as shown in the following diagram, and this data is divided by a fixed 17-digit binary number (0101).
8 bits The LSB of the Slave address is handled as the MSB in CRC-16 calculation.
Start of communications data
End of communications data
DSR Message and Response
The following description provides information on how to set DSR messages and what details are returned as responses. Each DSR message or response is divided into 8-bit blocks. Therefore, data must be set in 8-bit blocks for communications.
Data Read (Function Code: 03 Hex)
Due to parameter setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system is started up. If that should occur, use this section as a reference and apply the appropriate measures. Refer to 8-1 Protective and Diagnostic Functions, if the contents of the fault are displayed.
Parameters Fail Set
This occurs when n01 for parameter write-prohibit selection/parameter initialization is set to 0. Set n01 to an appropriate value according to the parameter to be set. There are some parameters that cannot be set during operation. Refer to the list of parameters. Turn the Inverter off and then make the settings. Turn the Inverter off and on. If the Digital Operator still does not display anything, the internal circuitry of the Inverter must have failed. Replace the Inverter.
The display does not change when the Increment or Decrement Key is pressed.
Parameter write-prohibit is input. The Inverter is operating.
The Digital Operator does not display anything.
Motor Fails to Operate
The motor does not operate with input through the control circuit terminals even though the frequency reference is correct.
The operation method setting is incorrect. If parameter n02 for operation mode selection is not set to 1 to enable the control circuit terminals, the RUN command cannot be executed through the control circuit terminals. Check and correct the setting in n02. Input in 2-wire sequence while 3-wire sequence is in effect and vice-versa. The Inverter will operate in 3-wire sequence according to the RUN, stop, and forward/stop commands if n37 for multi-function input 2 is set to 0. At that time, the Inverter will not operate if input in 2-wire sequence is ON. On the other hand, the Inverter in 2-wire sequence will only rotate in the reverse direction if input in 3-wire sequence is ON. Check and correct the setting in n37 or change the input method of the RUN command. The Inverter is not in RUN mode. When the PRGM or LO/RE indicator (red indicator) of the Digital Operator is lit, the Inverter does not start. Cancel the RUN command, press the Mode Key to change the mode of the Inverter, and restart the Inverter with the green indicator lit. The frequency reference is too low. If the frequency reference is set below the minimum output frequency set in n14, the Inverter will not operate. Raise the frequency reference to at least the minimum output frequency. The Inverter is in local mode. The Inverter in local mode starts with the RUN command given with the RUN Key pressed. Check the LO/RE indicator. If the display is Lo, the Inverter is in local mode. Press the Increment Key and set the Inverter to remote mode with rE displayed. If the above operation is not possible, a multi-function input is set to local/ remote selection. In that case, the mode can be changed with the multifunction input only. Turn the corresponding input terminal OFF so that the Inverter will be set to remote mode.
There may be resonance between the characteristic frequency of the mechanical system and the carrier frequency. If the motor is running with no problems and the machinery system is vibrating with a high-pitched whine, it may indicate that this is occurring. To prevent this type of resonance, adjust the carrier frequency value in n46. There may be resonance between the characteristic frequency of a machine and the output frequency of the Inverter. To prevent this from occurring, use the frequency jump function with the constants set in n49 through n51 to change the output frequency or install vibration-proof rubber on the motor base to prevent the resonance of the mechanical system.
Mechanical system makes unusual noise.
Resonance between the characteristic frequency of the mechanical system and the carrier frequency.
Resonance between the characteristic frequency of a machine and the output frequency of the Inverter.
Vibration and hunting are occurring.
Influence by the slip compensation function. The slip compensation function of the Inverter may influence the characteristic frequency of the mechanical system to cause vibration or hunting. In that case, increase the time constant in n67 for slip compensation. The larger this time constant is, however, the slower the response speed of the slip compensation function will be.
Motor vibrates excessively and does not rotate normally.
Motor Phase Interruption If one or two of the three phases of the motor are open, the motor will vibrate excessively and will not rotate. Check that the motor is wired correctly without any disconnection. The same phenomenon will occur if the output transistor of the Inverter is open and damaged. Check the balance of the Inverters output voltage as well.
8-2-10 Motor Rotates after Output of Inverter is Turned Off
Insufficient DC Control If the motor continues operating at low speed, without completely stopping, and after a deceleration stop has been executed, it means that the DC braking is not decelerating enough. In such cases, adjust the DC control as described below. Increase the parameter in n52 for DC control current. Increase the parameter in n53 for interruption DC control time.
8-2-11 Detects OV when Motor Starts and Motor Stalls
Insufficient DC control at startup Generation of OV and stalling can occur if the motor is turning when it is started. This can be prevented by slowing the rotation of the motor by DC braking before starting the motor. Increase the parameter in n54 for startup DC control time.
8-2-12 Output Frequency Does Not Reach Frequency Reference
The frequency reference is within the jump frequency range. If the jump function is used, the output frequency stays within the jump frequency range. Make sure that the jump width settings in n49 through n50 for jump frequencies 1 and 2 and jump width in n51 are appropriate. The upper-limit frequency can be obtained from the following formula. Maximum frequency in n09 frequency reference upper limit in n30/100 Make sure that the parameters in n09 and n30 are correct.

Checking the Name Plate
Example of 3-phase, 200VAC, 0.1kW (0.13HP)
Lift the cabinet by the heatsink. When moving the Inverter, never lift it by the plastic case or the terminal covers. Otherwise, the main unit may fall and be damaged. Mount the Inverter on nonflammable material (i.e., metal). Failure to observe this caution may result in a fire. When mounting Inverters in an enclosure, install a fan or other cooling device to keep the intake air temperature below 122F (50C) for IP20 (open chassis type), or below 105F(40C) for NEMA1 (TYPE1). Overheating may cause a fire or damage the Inverter. The VS mini generates heat. For effective cooling, mount it vertically. Refer to the figure in Mounting Dimensions on section 3.
Only begin wiring after verifying that the power supply is turned OFF. Failure to observe this warning may result in an electric shock or a fire. Wiring should be performed only by qualified personnel. Failure to observe this warning may result in an electric shock or a fire. When wiring the emergency stop circuit, check the wiring thoroughly before operation. Failure to observe this warning may result in injury. Always ground the ground terminal according to the local grounding code. Failure to observe this warning may result in an electric shock or a fire. For 400V class, make sure to ground the supply neutral. Failure to observe this warning may result in an electric shock or a fire. If the power supply is turned ON during the FWD(or REV) RUN command is given, the motor will start automatically. Turn the power supply ON after verifying that the RUN signal is OFF. Failure to observe this warning may result in injury. When the 3-wire sequence is set, do not make the wiring unless the multi-function input terminal parameter is set. Failure to observe this warning may result in injury.
Verify that the Inverter rated voltage coincides with the AC power supply voltage. Failure to observe this caution may result in personal injury or a fire. Do not perform a withstand voltage test on the Inverter. Performing withstand voltage tests may damage semiconductor elements. To connect a Braking Resistor, Braking Resistor Unit, or Braking Unit, follow the Procedure described in this manual. Improper connection may cause a fire. Always tighten terminal screws of the main circuit and the control circuits. Failure to observe this caution may result in a malfunction, damage or a fire. Never connect the AC main circuit power supply to output terminals U/T1, V/T2 or W/T3. The Inverter will be damaged and the guarantee will be voided. Do not connect or disconnect wires or connectors while power is applied to the circuits. Failure to observe this caution may result in injury. Do not perform signal checks during operation. The machine or the Inverter may be damaged.
Preautions for wiring
Wiring the control circuit terminals Screwdriver blade width
Insert the wire into the lower part of the terminal block and connect it tightly with a screwdriver.
Wire sheath strip length must be 5.5mm (0.22in).
Only turn ON the input power supply after confirming the Digital Operator or blank cover(optional) are in place. Do not remove the Digital Operator or the covers while current is flowing. Failure to observe this warning may result in an electric shock. Never operate the Digital Operator or DIP the switches with wet hands. Failure to observe this warning may result in an electric shock. Never touch the terminals while current is flowing, even if the Inverter is stopping. Failure to observe this warning may result in an electric shock. When the fault retry function is selected, stand clear of the Inverter or the load. The Inverter may restart suddenly after stopping. (Construct the system to ensure safety, even if the Inverter should restart.) Failure to observe this warning may result in injury. When continuous operation after power recovery is selected, stand clear of the Inverter or the load. The Inverter may restart suddenly after stopping. (Construct the system to ensure safety, even if the Inverter should restart.) Failure to observe this warning may result in injury. The Digital Operator stop button can be disabled by a setting in the Inverter. Install a separate emergency stop switch. Failure to observe this warning may result in injury.
If an alarm is reset with the operation signal ON, the Inverter will restart automatically. Reset an alarm only after verifying that the operation signal is OFF. Failure to observe this warning may result in injury. When the 3-wire sequence is set, do not make the wiring unless the multi-function input terminal parameter is set. Failure to observe this warning may result in injury.
Never touch the heatsinks, which can be extremely hot. Failure to observe this caution may result in harmful burns to the body. It is easy to change operation speed from low to high. Verify the safe working range of the motor and machine before operation. Failure to observe this caution may result in injury and machine damage. Install a holding brake separately if necessary. Failure to observe this caution may result in injury. If using an Inverter with an elevator, take safety measures on the elevator to prevent the elevator from dropping. Failure to observe this caution may result in injury. Do not perform signal checks during operation. The machine or the Inverter may be damaged. All the constants set in the Inverter have been preset at the factory. Do not change the settings unnecessarily. The Inverter may be damaged.
Maintenance and Inspection
Never touch high-voltage terminals on the Inverter. Failure to observe this warning may result in an electrical shock. Disconnect all power before performing maintenance or inspection, and then wait at least one minute after the power supply is disconnected. Confirm that all indicators are OFF before proceeding. If the indicators are not OFF, the capacitors are still charged and can be dangerous. Do not perform withstand voltage test on any part of the VS mini. The Inverter is an electronic device that uses semiconductors, and is thus vulnerable to high voltage. Only authorized personnel should be permitted to perform maintenance, inspections, or parts replacement. (Remove all metal objects (watches, bracelets, etc.) before starting work.) Failure to observe these warnings may result in an electric shock.
The control PCB board employs CMOS ICs. Do not touch the CMOS elements. They are easily damaged by static electricity. Do not connect or disconnect wires, connectors, or the cooling fan while power is applied to the circuit. Failure to observe this caution may result in injury.

Data display Indicators (Setting/Monitor item indicators)
Name Data display
Function Displays relevant data items, such as frequency reference, output frequency and parameter set values. Sets the frequency reference within a range between OHz and the maximum frequency.
FREF indicator FOUT indicator IOUT indicator MNTR indicator F/R idicator
The frequency reference can b& monitored or set while this indicator is lit. The output frequency of the Inverter can be monitored or set while this indicator is lit. The output current of the inverter this indicator is lit. The values set in U01 through U10 are monitored while this indicator is lit. The direction of rotation can be selected while this indicator is lit when operating the Inverter with the RUN Key.
Name LO/RE indicator
Function The operation of the Inverter through the Digital Operator or according to the sot parameteres is selectable while this indicator is lit. Note: The status of this indicator can be only monitored while the Inverter is in operation. Any RUN command input is ignored while this indicator is lit. The parameter in n01 through to n79 can be set or monitored while this indicator is lit. Note: While the Inverter is in operation, the paramete can be only monitored and only some parameti can be changed. Any RUN command input is ignored while this indicator is lit. Switches the setting and monitor item indicators in sequence. Parameter being set will be cancelled if this key is pressed before entering the setting. Increases multi-function monitor numbers, parameter num-bers and parameter set values. Decreases multi-function monitor numbers, parametei numbers and parameter sel values. Enters multi-function monitor numbers, parameter numl and internal data values after they are set or changed. Starts the Inverter running when the 3G3JV is in operation with the Digital Operator. Stops the Inverter unless parameter nO6 is not set to disable the STOP Key.
The following seven steps describe the recommended minimum operations to allow the J7 to control a connected motor in typical configuration, to allow simple operation in the quickest time: Step 1 initial checks
1-1 Checkpoints before connecting the power supply. Check that the power supply is as of the correct voltage. CIMR-J7AZ2@@@: Three phase 200 to 230VAC CIMR-J7AZB@@@: Single phase 200 to 240VAC (Wire R/L1 and S/L2) CIMR-J7AZ4@@@: Three phase 380 to 460VAC 1-2 Make sure that the motor output terminals (U/T1, V/T2, W/T3) are connected to the motor. 1-3 Ensure that the control circuit terminals and the control device are wired correctly. 1-4 Make sure that all control terminals are turned off. 1-5 Set the motor to no-load status (i.e. not connected to the mechanical system)
Step 2 Connecting the power supply and check the display status
2-1 After conducting the checks in step-1, connect the power supply. 2-2 If the display is normal when the power is connected it will read as follows;
RUN indicator: flashes ALARM indicator: off Setting/monitor indicators: FREF, FOUT or IOUT is lit. Data display: displays the corresponding data for the indicator that is lit. When fault has occurred, the details of the fault will be displayed. In that case, refer to users manual and take necessary action.
Step 3 Initializing parameters
To initialize the drive parameters to factory defaults, set parameter n01 = 8. This will set the J7 to accept start/stop commands in what in termed 2-wire control, i.e. 1 wire for a motor forward/stop command, and 1 wire for a motor reverse/stop command.
Key Sequence Indicator Display example Explanation Power On Press the Mode Key repeatedly until the PRGM indicator is lit.
Press the Enter Key. The data of n01 will be displayed.
Use the Increment or Decrement Key to set n01 to 8. The display will flash. Press the Enter Key so that the set value will be entered and the data display will be lit. In approximately 1s. The parameter number will be displayed.
Step 4 Set the motor rated current
This parameter is used for the electronic thermal function for motor overload detection (OL1). By correctly setting this, the J7 will protect an overloaded motor from burning out. Read the rated current (in amps) on the motor nameplate, and enter this into parameter n32. The example to the below shows entering a value of 1.8Amps.
Key Sequence Indicator Display example Explanation Displays the parameter number Use the Increment or Decrement Key until n32 is displayed.
Press the Enter Key. The data of n32 will be displayed. Use the Increment or Decrement Key to set the rated motor current. The display will flash. Press the Enter Key so that the set value will be entered and the data display will be lit. In approximately1s. The parameter number will be displayed.
Step 5 Set the motor rated frequency
This is the maximum frequency the motor can run and allows the J7 to properly control the motor. Read the rated frequency (in Hz) on the motor nameplate, and enter this into parameters n09 and n11.
Step 6 Set the operation command
This is the method for motor run and stop commands (i.e. how the inverter will start and stop the motor). The two basic operations are for the RUN and STOP/RESET keys on the Digital Operator, or for one of multi-function inputs through the control circuit terminals. To set the operation command, enter the appropriate value into parameter n02: 0 = RUN and STOP/RESET keys on the Digital Operator are enabled. 1 = Multi-function inputs through the control circuit terminals. The diagram to the below shows how to connect a switch to start/stop the motor in the forward direction in 2-wire control. Set parameter n02=1. To enable a separate switch for reverse rotation on control terminal S2, set parameter n36=2 (this is actually the factory default setting for n36).
FWD RUN/STOP REV RUN/STOP
Step 7 Set the frequency reference
This is the method for selecting the source for the motor speed command. The factory default is for the potentiometer on the digital Operator (FREF adjuster), in which case no setting is required. Frequency reference can also come from an external potentiometer, an analog output from a PLC, or up to 8 pre-programmed speeds held in the inverter and selected via the multi-function inputs. For example, to accept frequency reference from an external potentiometer, or a 0-10V analog out from a PLC, set parameter n03=2.
