Subfault: 28.6
Description: FCB 11/12 – Limit switch/reference cam not flush/overlapping with fixed stop
Response: Emergency stop + output stage inhibit
Cause Measure
Hardware limit switch or reference cam that has
not been selected was hit during reference travel
to fixed stop. Check whether the parameters set for reference
travel are correct.
During reference travel to fixed stop with selected
hardware limit switch or reference cam, the fixed
stop has been reached without hitting the hard-
ware limit switch or reference cam. Check whether the parameters set for reference
travel are correct.
Subfault: 28.7
Description: FCB 21 – Test torque greater than maximum torque at motor shaft
Response: Output stage inhibit
Cause Measure
The required test torque for the brake test is
higher than the maximum torque. It cannot be
generated by the motor/inverter combination. Reduce the test torque.
Subfault: 28.8
Description: FCB 21 – Test torque not reached
Response: Output stage inhibit
Cause Measure
Test torque required for brake test exceeds valid
limit values. – Reduce the test torque.
– Check the limit values.
Subfault: 28.9
Description: FCB 18 – Rotor position identification not possible
Response: Output stage inhibit
Cause Measure
Rotor position identification started with incre-
mental encoder but aborted prematurely. – Restart the rotor position identification.
– Check whether the encoder is connected cor-
rectly.
– Check whether encoder is defective.
Result of rotor position identification cannot be
stored in encoder. Select "inverter" as storage location.
Combination of "Automatic" mode and "Encoder"
storage location not permitted. Set the operating mode to "Manual" or the stor-
age location to "Inverter".
