The AC gear of the multimeter
measures the input value of the
servo LN (R/S/T), which is 220V ±
10% of the normal value. If the
power supply voltage is more than
220V+10% (380V+10%), check the
power supply voltage; if the power
supply voltage is normal, then in
servo BB state, monitor U0-05, the
voltage measured by the multimeter
* 1.414 < U0-05 (within 10V error),
then the servo driver is faulty and
needs to be sent back for repair.

(1) When the absolute value motor
is powered off, the memory position
depends on the battery on the
encoder cable. Once the encoder
cable
and
the
motor
are
disconnected, the power supply can
not be carried out, which will lead
to the loss of the current position of
the motor, it will alarm 222.
Please set F0-00=1 to clear the
alarm, it can be used normally.
(2) The alarm can be shielded by
using F0-79. When P0-79 is set to
