When the actual speed is larger than
P3-21/P3-22, it will alarm.

Position offset
too large
In position control,
the difference
between the given
position and the
actual position
exceeds the limit
value.
(1) Observe whether the motor is
blocked or not.
(2) Reducing the given speed of
position;
(3) Increase the deviation pulse limit
P0-23.
External UVW
Short Circuit
Discovered in
Self-Inspection
Check if the driver U3-00 is
identical with the motor code of the
motor label (the number after
MOTOR CODE), if not, please
change to the same one, then power
on again.
Inspection of motor UVW wiring,
need to be in phase sequence (brown
U, black V, blue W)
Driver UVW Output
Short Circuit or
Motor Failure
(1) Measure whether the UVW
phase resistance of the motor is
balanced. If the phase resistance is
unbalanced, replace the motor.
(2) Measure whether there is short
circuit between UVW and PE of the
motor. If there is short circuit,
replace the motor.
(3) Measure the driver side UVW
output through multimeter (diode
gear), black pen P+, red pen to
measure UVW; red pen P-, black
pen to measure UVW; if anyone is 0
in 6 groups of value, replace the
driver.
It is suggested that the motor should
be operated on an empty shaft to
eliminate the load problem.
High-speed
start-stop
instantaneous alarm
Increasing Acceleration and
Deceleration Time
(1) Check the encoder cable or
change a new one
(2) Set the servo driver to BB state
and the driver to U-10. Rotate the
motor shaft slowly by hand to see if
the value of U-10 changes normally,
increasing in one direction and
