What causes faulty auto-TRIP reset in Lenze DC Drives?
- S
  Stephanie FitzgeraldAug 25, 2025
  If you have a faulty auto-TRIP reset on your Lenze DC Drives, it could be due to more than 8 fault messages in 10 minutes. The solution depends on the specific fault message.

Why Lenze Inverter motor does not rotate?
- C
  Carlos RichardsAug 26, 2025
  If the Lenze Inverter motor isn't rotating, it could be due to several reasons: * The DC-bus voltage might be too low, in this case check the mains voltage. * The controller might be inhibited, so check the operating module. * The setpoint might be zero, so set a proper setpoint. * DC braking or the quick-stop function could be active, so disable them. * If a JOG setpoint is activated but the JOG frequency is zero, set the JOG frequency. * A fault might be indicated (refer to chapter 8.3 for fault details). * The mechanical motor brake might not be released, so release it.

What to do if Lenze Inverter shows OOV overvoltage error?
- L
  Lori JonesAug 27, 2025
  If your Lenze Inverter displays an OOV (Overvoltage) error, it could be due to: * Mains voltage being too high, check the voltage supply. * Feedback or braking operation issues. Try increasing deceleration times. If using brake choppers, check the selection and connection of the brake resistor and increase the deceleration times. * Earth leakage on the motor side. Inspect the motor cable and motor for earth faults, disconnecting the motor from the inverter to do so.

What to do if parameter transfer is faulty in Lenze 8203 DC Drives?
- M
  mhoffmanSep 23, 2025
  If you experience faulty parameter transfer via the operating module in Lenze DC Drives, and PAR1 and PAR2 are defective, it is absolutely necessary to repeat the data transfer or load the factory setting before enabling the controller.

What causes I x t overload in Lenze 8203?
- M
  mclaughlinamandaSep 13, 2025
  If you are experiencing I x t overload with your Lenze DC Drives, it might be due to frequent and too long acceleration processes with overcurrent. In this case, check drive dimensioning.

What causes overload during deceleration in Lenze 8203?
- D
  Dr. Michael Leon Jr.Sep 12, 2025
  If the Lenze DC Drives controller overloads during deceleration, the deceleration time might be too short. Increase the deceleration time. Also check the selection of the brake resistor or connect the brake chopper.

What causes overload during acceleration in Lenze 8203?
- D
  David MorrisonSep 12, 2025
  If the Lenze DC Drives inverter overloads during acceleration or experiences a short circuit, the acceleration time might be too short. Increase the acceleration time. Also, check the wiring for defective motor cable. Check the motor for an interturn fault.

What to do if Lenze DC Drives motor does not rotate?
- G
  Greg LeSep 4, 2025
  If your Lenze DC Drives motor isn't rotating, several factors could be at play. The DC-bus voltage might be too low, so you should check the mains voltage. The controller might be inhibited; in that case, check the display of the operating module for OFF, STOP, or AS_LC. Also, the setpoint could be zero, requiring you to modify it. DC braking or the Quick-stop function might be active, so deactivate them. If a JOG setpoint is activated with a JOG frequency of 0, set the JOG frequency to a non-zero value. Also, check the mechanical motor brake to ensure it is released.

What does EEr external fault mean on Lenze Inverter?
- C
  Christine BurkeSep 2, 2025
  If your Lenze Inverter displays an EE|External fault (TRIP-Set) error, it means a digital input assigned to the TRIP-Set function has been activated. Check the external encoder.
