Fault Cause
1. The Y servo board program is the
old version
2. Poor contact or broken wire of
the servo encoder
Motor overload
1. The wiring of the cable and en-
coder cable is wrong
2. The pulse frequency output by
the controller is too large
3. The electronic gear ratio is too
large
4. The servo gain setting is too
large
1. Y servo board program is an old
version
2. Mechanical stuck
1. Poor motor wiring
2. The motor is damaged
3. The Y servo board is damaged
Incorrect wiring phase sequence
Battery exhausted
Motor model does not match
– 50 –
Solution
1. Look at the screen "Internal Drive" -
"Y "Version Number", 1 means the
old version needs to be returned to
the factory to update the program
2. Check the encoder cable

Error Handling Method
Spare alarm
1. Whether the wiring of the servo motor
power cable and encoder cable is
correct and damaged
2. The pulse frequency output by the
controller is too large
3. Reduce electronic gear ratio
4. Try to adjust the servo gain manually
or automatically again
1. See "Internal Driver" - "Y Servo" on
the screen No version number indi-
cates that the old version needs to be
returned to the factory to update the
program.
2. Check the machinery
1. Check the motor wiring
2. Replace the motor
3. Replace the Y servo board
Wiring in the correct phase sequence
