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).

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 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.
