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.
Information: 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 the encoder.
Information: In "emergency mode" manual mode,
you can move the drive using the motor encoder
even if the external position encoder is faulty.
Subfault: 13.4
Description: Track measurement error
Response: Encoder 1 – latest critical fault
Cause
Measure
Error during track measurement.
– Switch the device off and on again.
– Check the wiring.
– Check interference sources (e.g. from EMC).
– Check the encoder. Replace if necessary.
Information: In "emergency mode" manual mode,
you can move the drive using the motor encoder
even if the external position encoder is faulty.
Subfault: 13.5
Description: Internal warning
Response: Encoder – warning
Cause
Measure
Encoder signaled warning.
– Check the wiring.
– Check interference sources (light beam inter-
rupted, reflector, data cables, etc.).
– Clean the sensor.
