Lenze 8200 vector Drive

Lenze 8200 vector Drive Fault Codes:

Fault Code and MeaningCause and Remedy
ccr
System fault
(PC: 71)
Cause: Strong interference injections on the control cables; Earth loops in the wiring.


Remedy:

  • Shield control cables.
ce0
Communication error on AIF
(PC: 61)
Cause: Faulty transmission of control commands via AIF.


Remedy:

  • Insert the communication module firmly into the diagnosis terminal.
ce1 / ce2 / ce3
Communication error on CAN-IN
(PC: 62, 63, 64)
Cause: CAN-IN object receives faulty data, or communication is interrupted.


Remedy:

  • Check plug connection bus module / FIF.

  • Check transmitter.

  • Increase monitoring time in C0357, if necessary.
ce4
BUS-OFF
(PC: 65)
Cause: Controller has received too many faulty telegrams via the system bus and has been disconnected.


Remedy:

  • Check bus termination.

  • Check shield connection of the cables.

  • Check PE connection.

  • Check bus load, reduce the baud rate if necessary.
ce5
CAN time-out
(PC: 66)
Cause: Remote parameterization slave does not respond; Parameter set change-over incorrectly parameterised; Internal error.


Remedy:

  • Check wiring of the system bus.

  • Check system bus configuration.

  • Ensure “parameter set change-over” signal (C0410/13/14) is connected to the same source in all sets.

  • Contact Lenze (if internal error).
FAn1
Fan failure
(PC: 95)
Cause: Fan is defective or not connected.


Remedy:

  • Replace fan.

  • Connect fan.

  • Check wiring.
LP1
Motor phase error
(PC: 32 / 182)
Cause: Failure of motor phases; Motor current is too low.


Remedy:

  • Check motor supply cables.

  • Check Vmin boost.

  • Connect motor with corresponding power or adapt with C0599.
LU
DC-bus undervoltage
Cause: Mains voltage too low; 400V controller connected to 240V mains.


Remedy:

  • Check mains voltage.

  • Check power supply module.

  • Connect controller to correct mains voltage.
OC1
Short circuit
(PC: 11)
Cause: Short circuit; Capacitive charging current of motor cable too high.


Remedy:

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

  • Check brake resistor and cable.

  • Use shorter/low-capacitance motor cable.
OC5
Controller overload
(PC: 15)
Cause: Frequent and too long overload periods during steady-state operation.


Remedy:

  • Check drive dimensioning.
OH
Heatsink temperature > 85 °C
(PC: 50)
Cause: Ambient temperature too high; Heatsink very dirty.


Remedy:

  • Allow controller to cool; provide better ventilation.

  • Clean heatsink.
OH4
Controller overtemperature
(PC: 54)
Cause: Controller is too hot inside.


Remedy:

  • Reduce controller load.

  • Improve cooling.

  • Check fan in the controller.
OU
DC-bus overvoltage
Cause: Mains voltage too high; Braking operation (deceleration too fast).


Remedy:

  • Check supply voltage.

  • Increase deceleration times.

  • Check dimensioning of external brake resistor.
Pr
Faulty parameter transfer
(PC: 75)
Cause: All parameter sets are defective.


Remedy:

  • Repeat data transfer or load Lenze setting before enabling controller.
sd5 / sd7
Wire breakage, analog input
(PC: 85 / 87)
Cause: Current on analog input < 4 mA for setpoint range 4...20 mA.


Remedy:

  • Close the circuit at the analog input.
rSt
Error during Auto-TRIP reset
(PC: 76)
Cause: More than 8 error messages within 10 minutes.


Remedy:

  • Dependent on the specific error message causing the trips.
