Detected
(Detected
when the
servomotor
power is
ON.)
The order of phases U, V,
and W in the servomotor
wiring is incorrect.
Check the servomotor
wiring. Confirm that the servomotor is
correctly wired.
An encoder fault occurred. --
If the alarm still occurs after turning
the power OFF and then ON again,
even though the servomotor is
correctly wired, the servomotor may
be faulty. Replace the servomotor.
