maximum reverse
speed is P3-22.
Inspection of motor UVW wiring,
need to be connected in phase
sequence.
(1) The maximum speed limit value
P3-21/P3-22 was reduced.
(2) To confirm whether the external
force makes the motor rotate too
fast, whether the pulse input
frequency is too high, and whether
the electronic gear ratio is too large.
(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 decreasing in one
direction (0-9999 cycle display).
When the actual speed is greater
than the value of P3-21/P3-22, the
alarm will be given.

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 P0-33 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
