Error defined in par. 32-67.
Causes:
Mechanically blocked or overloaded drive,
par. 32-67 Max. Tolerated Position Error too
small,
commanded speed greater than FC 300 para-
meters 4-13
Motor Speed High Limit and 3-03
Maximum Reference ,
commanded acceleration too great,
par. 32-60 Proportional Factor too small, or
FC 300 not enabled.
