Cause Remedy
A The setting of the Multi-turn Limit
Setting (Pn205) parameter in the
SERVOPACK is incorrect. Change parameter Pn205.
B The multi-turn limit has not been set
in the encoder. Check to be sure the Multi-turn
Limit Setting (Pn205) parameter in
the SERVOPACK is correct, create a
Multi-turn Limit Disagreement
Alarm (A.CC), and then execute the
encoder multi-turn limit setting
change (Fn013).
