The motor is short-circuited. Replace the motor.
(With the absolute position system,
the zero point must be established.)
6 Connect the cannon plug, and check
the insulation between the power
cable and FG.
There is no problem. Investigate item 7.

No abnormality is found in particular. Replace the drive unit. 7 Check for any abnormalities in the
motor's ambient environment.
(Ex.: Ambient temperature, cutting
water)
An abnormality was found in the
ambient environment.
Replace the motor and improve the
motor installation environment.

NC command error
The movement command data received from the NC was excessive.
Investigation details Investigation results Remedies SV SP
The rapid traverse rate is large. Check the rapid traverse rate limit. 1 Is the rapid traverse rate large for
using a sub-micron system or rotary
axis?
The rate is not especially large. Look for problems on the NC side,
such as not being able to follow up
the position FB.
