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
tank chains.

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

specification: No.5 battery, 3.6V (model
CP-B-BATT, CPT-B-BATT)
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
P0-79. 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
remembered when power off.
