Lenze Drive Fault codes

Lenze drives are a range of variable frequency drives designed to control the speed and torque of electric motors in a variety of industrial applications. And today we will look at possible Lenze drive fault codes.

Common Lenze Drive Fault Codes and their Meanings

Lenze actuators are known for their reliability, but like any electronic device, they may experience malfunctions or errors during operation. Here are some common trouble codes.

• E01: overcurrent/overload error.
• E02: engine overheat error.
• E03: communication error.
• E04: drive overtemperature error.
• E05: undercurrent error.
• E06: motor overvoltage error.
• E07: motor undervoltage error.
• E08: drive overvoltage error.
• E09: drive undervoltage error.
• E10: error related to engine stop.

It is important to note that fault codes and their meanings may vary depending on the specific Lenze drive model and firmware version. Always refer to the product documentation, user manual, or Lenze technical support for accurate information and troubleshooting advice specific to your Lenze drive.

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.

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.
• 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.
