Diagnostic messages and fault clearance
0Dh
Over-current
Definable as:
F
/-/-
Diagnostic memory: always
Short circuit in the motor, lines or brake chopper.
Output stage defective.
Incorrect parameterisation of the current regulator.
Check parameterisation of the current regulator. An incorrectly parameterised current regulator
can generate currents up to the short-circuit limit; as a rule this is clearly noticeable through high
frequency whistling. Inspection with the trace function in FCT (active current actual value).
Error message immediately after connecting to the load supply: Short circuit in the output stage.
The device must be replaced immediately.
Error message only occurs when setting the output stage enable: Disconnect the motor plug dir
ectly at the controller; if the error still occurs, the controller must be replaced. If the error only
occurs when the motor cable is connected, check the motor and cable for short circuits, e.g. with
a multimeter.
– Resettable: Cannot be reset; software reset is necessary.
Definable error reaction(s): A
0Eh
I²t malfunction motor
Definable as:
F
/-/-
Diagnostic memory: always
The I²t limit for the motor is reached. The motor or the drive system may be insufficient for the re
quired task.
Check the layout of the drive system.
Check the mechanical system for sluggishness.
Reduce load/dynamic response, longer time delays.
– Resettable: Error can only be reset after the cause of the error has been eliminated.
Definable error response(s): B,
C
11h
Software limit positive
Definable as:
F
/-/-
Diagnostic memory: optional
The position setpoint has reached or exceeded the respective software end position.
Check target data.
Check positioning area.
This error can be reset immediately. Afterwards start a corresponding positioning record or move
the drive by using the jogging function. Movements in a positive direction are blocked.
– Resettable: Error can be reset immediately.
