Lenze 8200 motec Drive Fault Codes:

Fault Code and MeaningCause and Remedy
nDEr (0)
No fault
Cause: –


Remedy: –
CCr (71)
System failure
Cause:

  • Strong interference injections on the control cables.

  • Earth loops in the wiring.


Remedy:

  • Shield control cable.
CE0 (61)
Communication error on AIF
Cause: Faulty transmission of control commands via AIF.


Remedy:

  • Insert the communication module properly into the diagnosis terminal.
CE1 (62)
Communication error on CAN-IN1 (sync control)
Cause: CAN-IN1 object receives faulty data or communication is interrupted.


Remedy:

  • Check plug connection of bus module ↔ FIF.

  • Check sender.

  • Increase monitoring time in C0357/1, if necessary.
CE4 (65)
BUS-OFF
Cause: Controller has received too many faulty telegrams via the system bus and has been disconnected.


Remedy:

  • Check whether bus termination is available.

  • Check shielding of the cables.

  • Check PE connection.

  • Check bus load, reduce the baud rate if necessary.
LP1 (32/182)
Error in motor phase
Cause:

  • Failure of one/several motor phases.

  • Motor current too low.


Remedy:

  • Check motor supply cables.

  • Check Umin boost.

  • Connect motor with a corresponding power or adapt motor with C0599.
LU (-)
DC bus undervoltage
Cause:

  • Mains voltage too low.

  • Voltage in DC-bus connection too low.

  • 400 V controller is connected to 240 V mains.


Remedy:

  • Check mains voltage.

  • Check power supply module.

  • Connect controller to correct mains voltage.
OC1 (11)
Short circuit
Cause:

  • Short circuit.

  • Capacitive charging current of the motor cable too high.


Remedy:

  • Search for cause of short circuit; check motor cable.

  • Check brake resistor and cable to brake resistor.

  • Use shorter/low-capacitance motor cable.
OH (50)
Heatsink temperature > +85 °C
Cause: Ambient temperature is too high.


Remedy:

  • Allow controller to cool and provide better ventilation.
OH4 (54)
Controller overtemperature
Cause: Controller too hot inside.


Remedy:

  • Reduce controller load.

  • Improve cooling.

  • Check fan in the controller.
Pr5 (79)
Internal fault
Cause: EEPROM is defective.


Remedy:

  • Contact Lenze.
Sd5 (85)
Open circuit – analog input 1
Cause: Current at analog input < 4 mA at setpoint range 4 ... 20 mA.


Remedy:

  • Close circuit at analog input.
