6.5.12 Fault 14 Encoder 2
Subfault: 14.1
Description: Position comparison check
Response: Encoder 2 – latest critical fault
Cause Measure
Faulty comparison between raw position and track counter of
absolute encoders
– Check the track signal wiring.
– Check interference source (e.g. from EMC).
– Replace encoder.
– Replace card.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 14.2
Description: Unknown encoder type
Response: Encoder 2 – latest critical fault
Cause Measure
Encoder type not known and not supported by inverter. – Check encoder type.
– Contact the SEW-EURODRIVE Service.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 14.3
Description: Invalid data
Response: Encoder 2 – latest critical fault
Cause Measure
Invalid encoder nameplate data (measuring steps/pulses per
revolution/multi-turn)
– Check startup parameters.
– Replace encoder.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 14.4
Description: Track measurement error
Response: Encoder 2 – latest critical fault
Cause Measure
Error during track measurement Switch the device off and on again.
– Check wiring.
– Check interference source (e.g. from EMC).
– Check encoder. Replace if necessary.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 14.5
Description: Internal warning
Response: Encoder – warning
Cause Measure
Encoder signaled warning – Check wiring.
– Check interference source (light beam interrupted, reflector,
data cable, etc.).
– Clean sensor.
Subfault: 14.6
Description: Signal level too low
Response: Encoder 2 – latest critical fault
Cause Measure
Vector below permitted limit during signal level monitoring – Check wiring.
– Check interference source (e.g. from EMC).
– Check encoder.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
