Solutions for Common Lenze Drive Fault Codes

Here are a few solutions for common trouble codes you may encounter with Lenze drives.

Overcurrent/overload error (E01)

  • Check the load connected to the drive. Make sure it is within the rated capacitance of the drive.
  • Make sure the engine is mechanically sound and not experiencing any mechanical problems or obstructions.
  • Inspect the wiring connections to make sure they are secure and up to date.
  • If the fault persists, consider using a higher-specification drive or contact Lenze technical support for further assistance.

Engine overheat error (E02)

  • Check the engine cooling system such as fans or ventilation and make sure they are working properly.
  • Check that the ambient temperature around the drive and motor is within acceptable limits.
  • Check for any obstructions or restrictions on airflow around the motor and drive.
  • If necessary, consider adding additional cooling means such as external fans or heatsinks.Lenze i550 fault codes

Communication error (E03)

  • Inspect communication cables and connectors for damage or lose connections. Make sure they are securely connected.
  • Check the communication settings and protocols between the drive and the control system.
  • Check for sources of interference or electrical interference that may affect communication signals.
  • Reset the communication interface on both the drive and the control system and try to establish communication again.

Drive overheat error (E04)

  • Ensure proper ventilation and cooling of the drive. Remove any dust or debris that may obstruct airflow.
  • Check that the cooling fans or heatsinks are working properly. Replace defective fans if necessary.
  • Ensure that the ambient temperature around the drive is within the specified limits.
  • Consider moving the disk or taking additional cooling measures if necessary.

Undercurrent fault (E05)

  • Check motor wiring and connections for loose or damaged wires. Repair or replace as needed.
  • Make sure that the load connected to the drive is not experiencing any mechanical problems or obstructions.
  • Check the motor parameters and, if necessary, adjust them according to the technical data of the connected motor.
  • If the problem persists, contact Lenze Technical Support for assistance.

Motor overvoltage error (E06)

  • Check the supply voltage to make sure it is within the specified range for the drive.
  • Check the wiring connections and make sure they are the correct size and securely connected.
  • If power surges are caused by power quality issues, consider installing surge protectors or voltage regulators.

Engine undervoltage error (E07)

  • Check the supply voltage and make sure it meets the minimum requirements of the drive.Lenze 8400 fault codes
  • Make sure the wiring connections are secure and up to date.
  • Repair any voltage fluctuations or power problems in the electrical system.

Drive overvoltage error (E08)

  • Check the supply voltage and make sure it is within the specified range for the drive.
  • Inspect the wiring connections to make sure they are secure and the correct size.
  • Install surge protectors or voltage stabilizers to mitigate power surges.

Drive undervoltage error (E09)

  • Check the voltage of the power supply and make sure it meets the minimum requirements of the drive.
  • Check electrical connections for loose or damaged wires and repair or replace them if necessary.
  • Repair any voltage fluctuations or power problems in the electrical system.

Engine stop error (E10)

  • Check for any mechanical obstruction or binding in the load or motor.
  • Make sure the motor parameters are set correctly and match the specifications of the connected motor.
  • Adjust the acceleration and deceleration parameters of the drive to ensure smooth motor operation.
