What does EPM error mean on Lenze Inverter?
- JJamie GrantSep 6, 2025
If the Lenze Inverter displays 'EPM error', it means the EPM is either missing or defective. To fix this, power down the system and replace the EPM.
What does EPM error mean on Lenze Inverter?
If the Lenze Inverter displays 'EPM error', it means the EPM is either missing or defective. To fix this, power down the system and replace the EPM.
What causes single phase fault in Lenze DC Drives?
If your Lenze DC Drive is showing a single phase fault, it means a mains phase has been lost. Check the mains voltage.
How to troubleshoot Remote keypad fault on Lenze Inverter?
If the Lenze Inverter shows 'Remote keypad fault', it means the remote keypad is disconnected. To resolve this, check the remote keypad connections.
What does external error mean on Lenze Inverter?
If the Lenze Inverter displays 'External error', it means the digital input “TRIP set” is active. To resolve this, remove the external error.
What to do if Lenze SMD DC Drives output frequency is 0 Hz?
If the Lenze DC Drive's output frequency is 0 Hz and the outputs U, V, W are inhibited, the setpoint might be 0 Hz. In this case, you should select a new setpoint. Alternatively, a quick stop might be activated through a digital input. To solve this, deactivate the quick stop.
What causes faulty auto-TRIP reset on Lenze SMD DC Drives?
If your Lenze DC Drive displays 'Faulty auto-TRIP reset', it means there have been more than 8 errors in 10 minutes. The solution depends on the specific error.
What does external error mean on Lenze DC Drives?
If your Lenze DC Drive reports 'External error', it means the digital input “TRIP set” is active. You should remove the external error to resolve this.
How to fix stop error on Lenze SMD?
If the Lenze DC Drive displays 'Stop (outputs U, V, W inhibited)', it indicates a LOW signal at terminal 28. Set terminal 28 to HIGH to resolve this.
What causes motor overload in Lenze SMD DC Drives?
If your Lenze DC Drive reports 'Motor overload (I2t overload)', the motor may be thermally overloaded due to impermissible continuous current or frequent/long acceleration processes. Check the controller selection and the setting of c20.
What causes overvoltage on DC bus in Lenze SMD DC Drives?
If you see 'Overvoltage on DC bus' on your Lenze DC Drive, it could be due to the mains voltage being too high, so you should check the mains voltage. It could also be caused by an excessively short deceleration time or the motor operating in generator mode. To resolve this, increase the deceleration time or use a dynamic braking option. Another cause could be earth leakage on the motor side, so check the motor/motor cable, separating the motor from the controller.
