Fault 15 Encoder 3
Subfault: 15.1
Description: Position comparison check
Response: FS – warning
Cause
Measure
Fault detected when comparing raw position and
track counter of absolute encoder.
– Check the track signal wiring.
– Check interference sources (e.g. from the area
of EMC).
– Replace the encoder.
– Replace the card.
INFORMATION
In "Emergency mode" manual mode, you can
move the drive using the motor encoder even if
the external position encoder is faulty.
Subfault: 15.10
Description: Position tolerance range exceeded
Response: FS – warning
Cause
Measure
Position outside tolerance range.
– Check the startup parameters.
– Check the wiring.
– Check interference sources (light beam inter-
rupted, reflector, signal cables, etc.).
– 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: 15.11
Description: Encoder data timeout
Response: FS – warning
Cause
Measure
Encoder process data triggered timeout state.
– Check interference sources (e.g. from the area
of EMC).
– Check the startup parameters.
INFORMATION
In "Emergency mode" manual mode, you can
move the drive using the motor encoder even if
the external position encoder is faulty.
