A.C10:
Servomotor Out
of Control
(Detected when
the servo is
turned ON.)
The order of phases
U, V, and W in the
motor wiring is not
correct.
Check the Servomotor
wiring.
Make sure that the Servo-
motor is correctly wired.
–
There is an error in the
setting of Pn080 =
n.X (Motor
Phase Sequence
Selection).
Check the setting of
Pn080 = n.X.
Set Pn080 = n.X to
an appropriate value.
