How to fix stop error on Lenze SMD?
- KKimberly MartinezAug 26, 2025
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.
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.
What to do if Lenze Inverter shows short-circuit or overload?
If the Lenze Inverter experiences a short-circuit or overload, there are several potential causes: * A short-circuit itself: Investigate the cause and inspect the motor cable. * Excessive capacitive charging current: Use shorter motor cables. * Acceleration time is too short: Increase the acceleration time and check the controller selection. * Defective motor cable: Check the wiring. * Internal fault in the motor: Check the motor. * Frequent and long overload: Check controller selection.
Why is my Lenze Inverter showing overvoltage on DC bus?
If your Lenze Inverter is experiencing an overvoltage on the DC bus, it could be due to several reasons: * The mains voltage might be too high: Verify the mains voltage. * The deceleration time might be excessively short, or the motor might be in generator mode: Increase the deceleration time or consider using a dynamic braking option. * Earth leakage on the motor side: Check the motor and motor cable, separating the motor from the controller to diagnose.
What causes motor overload on Lenze Inverter?
If the Lenze Inverter displays a motor overload (I2t overload), it means the motor is thermally overloaded. This can be due to: * Impermissible continuous current. * Frequent or excessively long acceleration processes. To resolve this: * Check the controller selection. * Check the setting of c20.
