If your Omron Inverter displays an LF Output Phase Loss, reset the fault after correcting its cause. Check the motor and Inverter capacity.
What does PF Input Phase Loss mean on my Omron CIMR-L7Z4011 and how to fix it?
If your Omron Inverter is showing a PF Input Phase Loss, tighten the input terminal screws. Also, check the power supply voltage.
What to do if Omron CIMR-L7Z4011 Inverter shows OH1 Heatsink Max Temp?
If your Omron Inverter displays an OH1 Heatsink Max Temp error, check for dirt build-up on the fans or heatsink. Reduce the ambient temperature around the drive. Replace the cooling fan(s) if necessary.
Why is my Omron Inverter displaying OL1 Motor Overload?
If your Omron Inverter is showing an OL1 Motor Overload, recheck the cycle time and the size of the load as well as the accel/decel times. Check the V/f characteristics and the setting of Motor Rated Current Setting.
What to do if Omron CIMR-L7Z4011 Inverter is not accelerating?
If your Omron Inverter is not accelerating as expected, try the following: Increase C1-01 (Acceleration Time 1). Increase L7-01 and L7-02 (Torque Limits) if they are low. Remove the ropes and repeat the tuning.
What to do if Omron CIMR-L7Z4011 shows OH Heatsink Over- temp?
If your Omron Inverter shows an OH Heatsink Over-temp error, check for dirt build-up on the fans or heatsink. Reduce the ambient temperature around the drive. If needed, replace the cooling fan(s).
How to troubleshoot GF Ground Fault in Omron CIMR-L7Z4011 Inverter?
To troubleshoot a GF Ground Fault in your Omron Inverter, try these steps: Remove the motor and run the Inverter without the motor. Check the motor for a phase to ground short. Verify the output current with a clampmeter to verify the DCCT reading. Also, check the control sequence for wrong motor contactor signals.
What causes OV DC Bus Overvolt on Omron CIMR-L7Z4011 and how to fix it?
If you are experiencing an OV DC Bus Overvolt error with your Omron Inverter, consider these solutions: Increase the deceleration time or connect a braking option. Check the power supply and decrease the voltage to meet the inverter’s specifications. Also, inspect the braking chopper/resistor.
