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.
Subfault: 28.13
Description: FCB 25 – Characteristic curve identification not possible
Response: Output stage inhibit
Cause Measure
Motor parameter measurement does not allow for
unique identification of the characteristic curve. Contact SEW-EURODRIVE Service.
Subfault: 28.14
Description: Modulo min. and max. swapped
Response: Emergency stop + output stage inhibit
Cause Measure
In active data set, value for "Modulo minimum" is
greater than value for "Modulo maximum", see
Monitoring functions\Limit values 1 or Monitoring
functions\Limit values 2. Swap the values for modulo minimum and mod-
ulo maximum.
