Why is my Lenze ESMD371L2YXA Inverter showing overvoltage on DC bus?
- R
  Robert NixonAug 30, 2025
  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 to do if Lenze Inverter shows short-circuit or overload?
- C
  Cody ClayAug 29, 2025
  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.

What to do if Lenze DC Drives have a communication error?
- J
  jareddavisAug 28, 2025
  If Lenze DC Drives have a communication error, it may be because the serial timer has timed out. Check the serial link connections.

What to do if Lenze DC Drives have a single phase fault?
- B
  Brooke FrederickAug 27, 2025
  If Lenze DC Drives have a single phase fault, it means a mains phase has been lost. Check the mains voltage.

How to resolve dynamic braking fault in Lenze DC Drives?
- A
  Abigail WhiteAug 27, 2025
  A dynamic braking fault in Lenze DC Drives typically means that the dynamic braking resistors are overheating. To resolve this, increase the deceleration time.

What to do if Lenze DC Drives show undervoltage on DC bus?
- S
  Steven BlackwellAug 27, 2025
  If Lenze DC Drives show undervoltage on the DC bus, it could be because the mains voltage is too low. Check the mains voltage.

What to do if Lenze DC Drives have controller overtemperature?
- T
  Tracy BoydAug 26, 2025
  If the controller has an overtemperature, it means the controller is too hot inside. To resolve this, reduce the controller load and improve cooling.

Why Lenze DC Drives show earth fault?
- M
  Melissa SimonAug 25, 2025
  An earth fault in Lenze DC Drives can occur if a motor phase is grounded, so you should check the motor and motor cable. It can also be due to excessive capacitive charging current of the motor cable, in this case use shorter motor cables with lower charging current.
