Subfault: 9.3
Description: Absolute rotor position not available
Response: Output stage inhibit
Cause Measure
The current control mode requires an absolute rotor position.
The encoder selected for "Source is actual speed" does not
provide an absolute rotor position.
Use an absolute encoder, or identify the rotor position 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 premagnetization. Check the cabling, or disable the function "current monitoring
during premagnetization".
Subfault: 9.5
Description: Maximum output frequency exceeded
Response: Output stage inhibit
Cause Measure
Maximum output frequency exceeded. Reduce maximum speed.
Subfault: 9.6
Description: Maximum model speed exceeded
Response: Output stage inhibit
Cause Measure
The speed of the drive calculated in ELSM
®
control mode is too
high for motor control.
If possible minimize the "Speed/position controller sampling
cycle", or reduce the speed.
Subfault: 9.8
Description: Flux model error
Response: Output stage inhibit
Cause Measure
The rotor flux calculated by the motor model is not plausible, or
the calculated internal voltage is too small.
– Check configuration data.
– Check motor data.
– Check machine: Idle state or too low speed.
– Contact the SEW-EURODRIVE Service.
Subfault: 9.9
Description: Parameter measurement not possible with active motor type
Response: Output stage inhibit
Cause Measure
Parameter measurement is only possible with "asynchronous"
and "synchronous" motor types. No magnetic reluctance and
LSPM motors.
Select the correct motor type.
Subfault: 9.10
Description: Rotor stall monitoring
Response: Output stage inhibit
Cause Measure
The current control cannot hold the load torque. The deviation
between stationary setpoint voltage and actual voltage is too
large.
Reduce the load torque (hoist) in the controlled system.
6.5.8 Fault 10 Data flexibilization layer
Subfault: 10.1
Description: Initialization
Response: Application stop + output stage inhibit
Cause Measure
Error during init task. The init task issued a return code != 0. Check the program.
