Make sure that these protective covers are on the product before use. Consult your OMRON representative when using the product after a long period of storage.

! WARNING ! WARNING

Do not touch the inside of the Inverter. Doing so may result in electrical shock. Operation, maintenance, or inspection must be performed after turning OFF the power supply, confirming that the CHARGE indicator (or status indicators) are OFF, and after waiting for the time specified on the front cover. Not doing so may result in electrical shock. Do not damage, pull on, apply stress to, place heavy objects on, or pinch the cables. Doing so may result in electrical shock. Do not touch the rotating parts of the motor under operation. Doing so may result in injury. Do not modify the product. Doing so may result in injury or damage to the product. Do not store, install, or operate the product in the following places. Doing so may result in electrical shock, fire or damage to the product. S Locations subject to direct sunlight. S Locations subject to temperatures or humidity outside the range specified in the specifications. S Locations subject to condensation as the result of severe changes in temperature. S Locations subject to corrosive or flammable gases. S Locations subject to exposure to combustibles. S Locations subject to dust (especially iron dust) or salts. S Locations subject to exposure to water, oil, or chemicals. S Locations subject to shock or vibration.

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.
Provide a separate holding brake when necessary. Not doing so may result in injury.
Do not perform a signal check during operation. Doing so may result in injury or damage to the product.
Do not carelessly change settings. Doing so may result in injury or damage to the product.
Maintenance and Inspection Precautions

Do not touch the Inverter terminals while the power is being supplied.
Maintenance or inspection must be performed only after turning OFF the power supply, confirming that the CHARGE indicator (or status indicators) is turned OFF, and after waiting for the time specified on the front cover. Not doing so may result in electrical shock.
Maintenance, inspection, or parts replacement must be performed by authorized personnel. Not doing so may result in electrical shock or injury.
Do not attempt to take the Unit apart or repair. Doing either of these may result in electrical shock or injury.
Carefully handle the Inverter because it uses semiconductor elements. Careless handling may result in malfunction.
Do not change wiring, disconnect connectors, the Operator, or optional items, or replace fans while power is being supplied. Doing so may result in injury, damage 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 (100-V-class Units). Take measures against overcurrent, overload, and overheating by using the Motor Protection Settings.
CAUTION Use 75C copper wires or equivalent. Low voltage wires shall be wired with Class I Wiring.
H Motor Protection Settings 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.

4-1-1 Fault Detection (Fatal Error)
The Inverter will detect the following faults if the Inverter or motor burns or the internal circuitry of the Inverter malfunctions. When the Inverter detects a fault, the fault code will be displayed on the Digital Operator, the fault contact output will operate, and the Inverter output will be shut off causing the motor to coast to a stop. The stopping method can be selected for some faults, and the selected stopping method will be used with these faults. If a fault has occurred, refer to the following table to identify and correct the cause of the fault. Use one of the following methods to reset the fault after restarting the Inverter. If the operation command is being input, however, the reset signal will be ignored. Therefore, be sure to reset the fault with the operation command turned off. S Turn on the fault reset signal. A multi-function input (n36 to n39) must be set to 5 (Fault Reset). S Press the STOP/RESET Key on the Digital Operator. S Turn the main circuit power supply off and then on again.

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.
Provide a separate holding brake when necessary. Not doing so may result in injury.
Do not perform a signal check during operation. Doing so may result in injury or damage to the product.
Do not carelessly change settings. Doing so may result in injury or damage to the product.
Maintenance and Inspection Precautions
Do not touch the Inverter terminals while the power is being supplied.
Maintenance or inspection must be performed only after turning OFF the power supply, confirming that the CHARGE indicator (or status indicators) is turned OFF, and after waiting for the time specified on the front cover. Not doing so may result in electrical shock.
Maintenance, inspection, or parts replacement must be performed by authorized personnel. Not doing so may result in electrical shock or injury.
Do not attempt to take the Unit apart or repair. Doing either of these may result in electrical shock or injury.
Carefully handle the Inverter because it uses semiconductor elements. Careless handling may result in malfunction.
Do not change wiring, disconnect connectors, the Operator, or optional items, or replace fans while power is being supplied. Doing so may result in injury, damage to the product, or malfunction.
Warnings for UL/cUL Marking

n34 Setting range Motor Protection Time 1 to 60 (min) Unit of setting 1 min Changes during operation Default setting No 8
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.

H Fault Displays and Processing
Fault display %c Fault name and meaning Overcurrent (OC) The Inverter output current is as high as or higher than 200% of the rated output current. Probable cause and remedy A short-circuit or ground fault has occurred and at the Inverter output. Check and correct the motor power cable. The V/f setting is incorrect. Reduce the V/f set voltage. The motor capacity is too large for the Inverter. Reduce the motor capacity to the maximum permissible motor capacity. The magnetic contactor on the output side of the Inverter has been opened and closed. Rearrange the sequence so that the magnetic contactor will not open or close while the Inverter has current output. The output circuit of the Inverter is damaged. %U Replace the Inverter. Overvoltage (OV) The deceleration time is too short. The main circuit DC voltage Increase the deceleration time. has reached the overvoltage The power supply voltage is too high. detection level (100-V models: Decrease the voltage so it will be within specifications. 410 V DC min.).

Power supply to the Inverter has phase loss, power input terminal screws are loose, or the power cable is disconnected. Check the above and take necessary countermeasures. Incorrect power supply voltage Make sure that the power supply voltage is within specifications. Momentary power interruption has occurred. Use the momentary power interruption compensation (Set n47 so that the Inverter restarts after power is restored) Improve the power supply. The internal circuitry of the Inverter is damaged.
Radiation fin overheated (OH) The temperature of the radiation fins of the Inverter has reached 110_C 10_C.
Change the Inverter. The ambient temperature is too high. Ventilate the Inverter or install a cooling unit. The load is excessive. Reduce the load. Decrease the Inverter capacity. The V/f setting is incorrect. Reduce the V/f set voltage. The acceleration/deceleration time is too short. Increase the acceleration/deceleration time. The ventilation is obstructed. Change the location of the Inverter to meet the installation conditions. The cooling fan of the Inverter does not work. Replace the cooling fan.
Fault display %l1 Fault name and meaning Motor overload (OL1) The electric thermal relay actuated the motor overload protective function. Probable cause and remedy The load is excessive. Reduce the load. Decrease the Inverter capacity. The V/f setting is incorrect.

Maintenance Operations 4-2 Inspection and Maintenance

H Daily Inspection

Check the following items while the system is operating. No abnormal noise or vibration in the motor No abnormal heat generation Output current monitor display is not a higher value than normal Cooling fan installed in Inverter is operating normally (models with fans only)

H Periodic Inspection

Check the following items when performing periodic maintenance. Always wait at least one minute after the power supply has been turned OFF and all the LED indicators have turned OFF before performing maintenance. Touching the terminals immediately after the power is turned OFF may result in electric shock. No looseness in terminal screws No electroconductive dust or oil mist attached to terminal block or the Inverters internal parts No looseness in Inverter mounting screws No accumulation of dirt or dust on cooling fin (heat sink) No dust accumulated in the ventilation holes No abnormality in external appearance Cooling fan in control panel is operating normally (Check that there is no abnormal noise or vibration, and that the total ON time has not exceeded the specified value.)
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.
