Subfault: 15.53
Description: Maximum frequency exceeded
Response: FS – warning
Cause
Measure
Maximum permitted signal frequency exceeded.
– Check the maximum input frequency.
– Check the wiring.
– Check interference sources.
– Apply the shield of the encoder cable over a
large area.
– Check the encoder.
Subfault: 15.54
Description: Cross comparison error
Response: FS – warning
Cause
Measure
Cross comparison error in encoder evaluation.
– Check the wiring.
– Check interference sources.
– Apply the shield of the encoder cable over a
large area.
– Check the encoder.
Subfault: 15.55
Description: Signal level monitoring
Response: FS – warning
Cause
Measure
Track signal level not within tolerance band.
– Check the wiring.
– Check interference sources.
– Apply the shield of the encoder cable over a
large area.
– Check the encoder.
Subfault: 15.56
Description: Maximum speed exceeded while encoder fault muting is active.
Response: FS – system error
Cause
Measure
Maximum permitted speed exceeded while en-
coder fault muting is active.
– Check the maximum speed of the application
while encoder fault muting is active and adjust if
necessary.
– Check the parameter setting of the safety card
and adjust if necessary.
