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 the 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".
Subfault: 28.10
Description: FCB 25 – Unbalanced motor phases
Response: Output stage inhibit
Cause
Measure
Significantly different values determined in the
three phases while measuring stator resistances.
– Check whether the motor is connected cor-
rectly.
– Check all contact points on the motor and in-
verter.
– Check the motor and motor cable for damage.
Subfault: 28.11
Description: FCB 25 – At least one phase with high resistance
Response: Output stage inhibit
Cause
Measure
At least one motor phase could not be measured
during motor parameter measurement.
– Check whether the motor is connected cor-
rectly.
– Check all contact points on the motor and in-
verter.
– Check the motor and motor cable for damage.
Subfault: 28.12
Description: FCB 25 – Timeout during stator resistance measurement
Response: Output stage inhibit
Cause
Measure
Motor parameter measurement activated while
motor is turning.
– Stop the motor.
– Start motor parameter measurement when the
motor is at standstill.
