Error 13 encoder 1 fault
Subfault: 13.1
Description: Position comparison check
Response: Encoder 1 – latest critical fault
Cause
Measure
Faulty comparison between raw position and
track counter of absolute encoders.
– Check the track signal wiring.
– Check interference sources (e.g. from the area
of EMC).
– Replace encoder.
– Replace the card.
Note: In "Emergency mode" manual mode, you
can move the drive using the motor encoder even
if the external position encoder is faulty.
Subfault: 13.2
Description: Unknown encoder type
Response: Encoder 1 – latest critical fault
Cause
Measure
Encoder type not known and not supported by in-
verter.
– Check the encoder type.
– Contact SEW-EURODRIVE Service.
Note: In "Emergency mode" manual mode, you
can move the drive using the motor encoder even
if the external position encoder is faulty.
Subfault: 13.3
Description: Invalid data
Response: Encoder 1 – latest critical fault
Cause
Measure
Invalid encoder nameplate data (measuring
steps/pulses per revolution/multi-turn).
– Check the startup parameters.
– Replace encoder.
Note: In "Emergency mode" manual mode, you
can move the drive using the motor encoder even
if the external position encoder is faulty.
