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.

Disconnect the power supply of the
driver, check the connection of the
encoder cable, if there is cable
loosening, it is recommended to use
the multimeter to test the
conduction condition; after
eliminating errors, power on again
Hot plugging is strictly prohibited,
and special cables are required for

Please replace the battery while
keeping the power supply ON of the
servo driver in order to avoid the

No.5 battery, 3.6V (model

Power on alarm for
new machine
(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
1, it will be used as a single-loop
absolute value motor, and the
current position will not be
