dropped. The absolute position data is retained.
A cooling fan built in the drive unit stopped.
The designated position shift amount of turret indexing is outside the
setting range.
As an orientation feedback error occurred, the retrial has been
conducted.
Over-regeneration detection level exceeded 80%.
Overload detection level exceeded 80%.
The motor was continuously rotated at a speed exceeding the rated
speed.
Deviation between the absolute and relative position data was
detected.
A parameter setting was outside the setting range.
Control axis detachment was commanded.
Emergency stop was input from the CNC.
Regeneration that are beyond the power supply limitation has
frequently occurred.
