Fault 9 Control mode
Subfault: 9.1
Description: Magnetization of motor not possible
Response: Output stage inhibit
Cause
Measure
The user-defined current limit or output stage mo-
nitoring have reduced the possible maximum cur-
rent to such a degree that the required magnetiz-
ing current cannot be set.
– Reduce the output stage utilization, e.g. by re-
ducing the PWM frequency or reducing the load.
– Increase the user-defined current limit.
Subfault: 9.2
Description: Requested operating mode not possible with active control mode
Response: Output stage inhibit
Cause
Measure
The current FCB activated an operating mode.
The active control mode does not support this op-
erating mode, for example "position control" or
"torque control" with U/f control mode.
– Use a control mode that supports the required
operating mode. Connect an encoder if neces-
sary.
– Select an operating mode that is supported by
the current control mode.
Subfault: 9.3
Description: Absolute rotor position not available
Response: Output stage inhibit
Cause
Measure
The current control mode requires an absolute ro-
tor position. The encoder selected for "Source of
actual speed" does not provide an absolute rotor
position.
Use an absolute encoder, or identify the rotor po-
sition using FCB 18.
Subfault: 9.4
Description: Correct current supply of motor not possible
Response: Output stage inhibit
Cause
Measure
Failed to set required current during premagnetiz-
ation.
Check the cabling, or disable the function "Cur-
rent monitoring during premagnetization".
Subfault: 9.5
Description: Maximum output frequency exceeded
Response: Output stage inhibit
Cause
Measure
Maximum output frequency exceeded.
Reduce the maximum speed.
