Unconnected encoder
cable or poor contact
Check whether the value of
U0-54 increases rapidly. If yes,
the encoder circuit is
disconnected.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 tank chains.

Check whether the value of
U0-79 and U0-54 increase. If yes,
the encoder is interfered. Encoder

voltage alarm
(can shield this
alarm)
Battery Voltage in
Battery Box of Encoder
cable is less than 2.75V
Please replace the battery while
keeping the power supply ON of
the servo driver in order to avoid
the error of encoder position
information. Battery
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 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
remembered when power off.
