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 the SEW‑EURODRIVE Service.
Subfault: 28.14
Description: Modulo min. and max. swapped
Response: Emergency stop + output stage inhibit
Cause
Measure
In the active data set, the value for "Modulo min-
imum" is greater than the value for "Modulo maxi-
mum"; see Monitoring functions\Limit values 1 or
