What causes undervoltage on DC bus in Lenze Inverter?
If the Lenze Inverter shows 'Undervoltage on DC bus', the mains voltage might be too low. Check the mains voltage to ensure it is within the required range.
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.
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.
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 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.
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 to do if Lenze SMD have overvoltage on DC bus?
Overvoltage on the DC bus in Lenze DC Drives may be due to several reasons. It can be caused by mains voltage being too high (check mains voltage), an excessively short deceleration time or the motor operating in generator mode (increase deceleration time or use dynamic braking option), or earth leakage on the motor side (check motor/motor cable, separating the motor from the controller).
What causes Lenze SMD DC Drives to have earth fault?
An earth fault in Lenze DC Drives may be caused by a grounded motor phase (check motor/motor cable) or excessive capacitive charging current of the motor cable (use shorter motor cables).
What to do if Lenze DC Drives show external error?
If your Lenze DC Drive shows an external error, it means the digital input “TRIP set” is active. Remove the external error to resolve this.
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.
