in injury, damage , Doing so may result to the product, or malfunction.
Warnings for UL/cUL Marking
Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON. The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent electrical shock, disconnect all power before servicing the Inverter. Then wait at least one minute after the power supply is disconnected and all indicators are OFF. Do not perform a withstand voltage test on any part of the Inverter. This electronic equipment uses semiconductors and is vulnerable to high voltage. Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF. Never touch the printed control board (PCB) while the power supply is turned ON. The Inverter is not suitable for use on a circuit capable of delivering more than 5.000 RMS symmetrical amperes, 250 volts maximum (200V-class Units) or 18.000 RMS symmetrical amperes, 480 V maximum (400-V-class Units).
CAUTION Use 75C copper wires or equivalent. Low voltage wires shall be wired with Class I Wiring.

I Motor Protection Settings 3G3JV Rated motor current (n32)
Set the rated motor current (n32) in order to prevent the motor from burning due to overloading. Check the rated current on the motor nameplate and set the parameter. This parameter is used for the electronic thermal function for motor overload detection (OL1). By setting the correct parameter, the overloaded motor will be protected from burning. n32 Setting range Rated Motor Current 0.0% to 120% (A) of rated output current of Inverter Unit of setting 0.1 A Changes during operation Default setting No (see note 1)
Note 1. The standard rated current of the maximum applicable moter is the default rated motor current. Note 2. Motor overload detection (OL1) is disabled by setting the parameter to 0.0.
Motor Protection Characteristics (n33 and n34)
This parameter setting is for motor overload detection (OL1). n33 Setting range Motor Protection Characteristic Selection 0 to 2 Unit of 1 setting Changes during operation Default setting No 0
Set Values Value 2 Description Protection characteristics for general-purpose induction motors Protection characteristics for Inverter-dedicated motors No protection
This parameter is used to set the electric thermal characteristics of the motor to be connected. Set the parameter according to the motor. If a single Inverter is connected to more than one motor, set the parameter to 2 for no protection. The parameter is also disabled by setting n32 for rated motor current to 0.0. n34 Setting range Motor Protection Time 1 to 60 (min) Unit of setting 1 min Changes during operation Default setting No 8
I Motor Protection Settings 3G3MV Rated motor current (n36)
Check the motor nameplate and set this parameter to the rated current. This parameter is used as a vector control constant. Be sure to set the parameter correctly. This set value is also used for determining the electronic thermal characteristics to protect the motor from overheating. The correct set value protects the motor from burning that may result form overloading. n036 Setting range Rated Motor Current 0.0% to 150% (A) of rated output current of the Inverter Register Unit of setting 0124 Hex 0.1 A Changes during No operation Default setting See note

Note The default setting for this parameter is the standard rated current of the maximum applicable motor.
Motor Protection Functions (n037 and n038)
This parameter setting is for motor overload detection (OL1). n037 Setting range Motor Protection Characteristics 0 to 2 Register Unit of setting 0125 Hex 1 Changes during operation Default setting No 0
Note The default setting for this parameter is the standard rated current of the maximum applicable motor. Set Values Value 2 Description Protection characteristics for general-purpose induction motors Protection characteristics for Inverter-dedicated motors No protection
This parameter is used to set the electric thermal characteristics of the motor to be connected. Set the parameter according to the motor. If a single Inverter is connected to more than one motor, set the parameter to 2 for no protection. The parameter is also disabled by setting n36 for rated motor current to 0.0.

Set values This parameter is used to set the electronic thermal protection constant of motor overload detection OL1. The default setting does not need any changes in normal operation. To set the parameter according to the characteristics of the motor, confirm the thermal time constant with the motor manufacturer and set the parameter with some margin. In other words, set the value a little shorter than the thermal time constant. To detect motor overloading more quickly, reduce the set value, provided that it does not cause any application problems.

! WARNING ! Caution

Do not touch the Inverter radiator, regenerative resistor, or Servomotor while the power is being supplied or soon after the power is turned OFF. Doing so may result in a skin burn due to the hot surface. Do not conduct a dielectric strength test on any part of the Inverter. Doing so may result in damage to the product or malfunction. Take appropriate and sufficient countermeasures when installing systems in the following locations. Not doing so may result in equipment damage. S Locations subject to static electricity or other forms of noise. S Locations subject to strong electromagnetic fields and magnetic fields. S Locations subject to possible exposure to radioactivity. S Locations close to power supplies.
Transportation Precautions
Do not hold by front cover or panel, instead, hold by the radiation fin (heat sink) while transporting the product. Doing so may result in injury. Do not pull on the cables. Doing so may result in damage to the product or malfunction. Use the eye-bolts only for transporting the Inverter. Using them for transporting the machinery may result in injury or malfunction.

Installation Precautions

Provide an appropriate stopping device on the machine side to secure safety. (A holding brake is not a stopping device for securing safety.) Not doing so may result in injury. Provide an external emergency stopping device that allows an instantaneous stop of operation and power interruption. Not doing so may result in injury. Be sure to install the product in the correct direction and provide specified clearances between the Inverter and control panel or with other devices. Not doing so may result in fire or malfunction. Do not allow foreign objects to enter inside the product. Doing so may result in fire or malfunction. Do not apply any strong impact. Doing so may result in damage to the product or malfunction.

Wiring Precautions

Wiring must be performed only after confirming that the power supply has been turned OFF. Not doing so may result in electrical shock. Wiring must be performed by authorized personnel. Not doing so may result in electrical shock or fire. Be sure to confirm operation only after wiring the emergency stop circuit. Not doing so may result in injury. Always connect the ground terminals to a ground of 100 or less. Not connecting to a proper ground may result in electrical shock.

Install external breakers and take other safety measures against short-circuiting in external wiring. Not doing so may result in fire. Confirm that the rated input voltage of the Inverter is the same as the AC power supply voltage. An incorrect power supply may result in fire, injury, or malfunction. Connect the Braking Resistor and Braking Resistor Unit as specified in the manual. Not doing so may result in fire. Be sure to wire correctly and securely. Not doing so may result in injury or damage to the product. Be sure to firmly tighten the screws on the terminal block. Not doing so may result in fire, injury, or damage to the product. Do not connect an AC power to the U, V, or W output. Doing so may result in damage to the product or malfunction. Set the multi-function contact input parameter for NC contact terminals (e.g., 3-wire sequence) before wiring them. If the parameters default setting is used, the motor may start running when the input terminal S2 is turned ON.
Operation and Adjustment Precautions
Turn ON the input power supply only after mounting the front cover, terminal covers, bottom cover, Operator, and optional items. Not doing so may result in electrical shock. Do not remove the front cover, terminal covers, bottom cover, Operator, or optional items while the power is being supplied. Doing so may result in electrical shock or damage to the product. Do not operate the Operator or switches with wet hands. Doing so may result in electrical shock. Do not touch the inside of the Inverter. Doing so may result in electrical shock. Do not come close to the machine when using the error retry function because the machine may abruptly start when stopped by an alarm. Doing so may result in injury. Do not come close to the machine immediately after resetting momentary power interruption to avoid an unexpected restart (if operation is set to be continued in the processing selection function after momentary power interruption is reset). Doing so may result in injury.
Provide a separate emergency stop switch because the STOP Key on the Operator is valid only when function settings are performed. Not doing so may result in injury.
Be sure to confirm that the RUN signal is turned OFF before turning ON the power supply, resetting the alarm, or switching the LOCAL/REMOTE selector. Doing so while the RUN signal is turned ON may result in injury.
Be sure to confirm permissible ranges of motors and machines before operation because the Inverter speed can be easily changed from low to high. Not doing so may result in damage to the product.

RUN Key STOP/RESET Key

Note For safetys reasons, the reset will not work while a RUN command (forward or reverse) is in effect. Wait until the RUN command is OFF before resetting the Inverter.
2-1-2 Accepting Operation Commands While Changing Parameters
With the default settings, the Inverter will not accept operation commands when parameter settings are being changed. This functions as a safety measure to prevent the motor from rotating if the operation command is mistakenly set to ON when changing parameters. Depending on the operating conditions, however, the user may want to have operation commands accepted even while parameters are being changed. In that case, change the following settings.
H Using the Indicators to Determine When Operation Commands Can Be Accepted
The indicators on the Digital Operator can be used to determine if operation commands will be accepted or not while changing parameters. Green: Operation commands will be accepted if the indicator lights green. Red: Operation commands will not be accepted after the Inverter stops if an indicator lights red. Therefore, if the indicator lights red when changing parameters or when switching between local and remote operation, operation will continue, but once the Inverter stops, the Inverter will not operate even if the operation command is set to ON again. The FREF indicator will light when the power supply is turned ON.
Indicator Color Name Acceptance of operation commands During Stopped operation Yes Yes
FREF FOUT IOUT MNTR F/R LO/RE PRGM
Green Green Green Green Green Red Red
Frequency Reference/Monitor Output Frequency Monitor Output Current Monitor Multifunction Monitor Operator RUN command forward/reverse operation selection Local/Remote Selection Parameter Number/Setting

No ( (See note.) )

Note Perform the settings given in the following description to have operation commands accepted while the red indicator is lit (i.e., while changing parameters or switching between local and remote.) Set n01 (Parameter writeprohibit selection/parameter initialization) to 5. S The default value for n01 is 1. S Operation commands will not be accepted when n01 itself is being changed. S Some parameters cannot be changed during operation. Those parameters cannot be changed during operation even if the setting for n01 is changed. S When n01 is changed to 5, an operation command will be accepted even when changing parameters, such as during trial operation. Thoroughly check safety before changing any setting.

H Periodic Maintenance of Components
The Inverter is constructed from many components, the normal operation of which is required for the essential functionality of the Inverter. Maintenance is required for some of the electronic components depending on the operating conditions. To enable the Inverter to operate normally for a long time, periodic inspection and component replacement must be performed to suit the service life of these components. (Source: Instructions for Periodic Inspection of General Purpose Inverter (JEMA)) The guidelines for periodic inspection depend on the Inverters installation environment and operating conditions. The maintenance periods for the Inverter are listed below. Use this to determine when periodic maintenance is required. The guidelines for periodic maintenance are as follows: Cooling fan: 2 to 3 years Electrolytic capacitor: 10 years Fuse: 10 years These guidelines are applicable for an operating environment in which the ambient temperature is 40C, the load rate is 80%, the operating time is 8 hours per day, and the product is installed according to the instructions in the manual.
To extend the maintenance period, it is recommended to lower the ambient temperature and shorten the ON time as much as possible. Note Contact your OMRON sales representative for details on maintenance methods.
