Warning)
Running
under
heavy load for a
long time
Re-consider the capacity of the motor,
monitor the U0-02 torque during
operation, whether it is in the value of
more than 100 for a long time, if yes,
please chose the large-capacity motor
or load reduction.
Excessive

temperature
(1) Enhance ventilation measures to
reduce ambient temperature;
(2) Check whether the fan rotates when
the servo is enabled; when the module

Motor code not
match
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.
UVW

error
Inspection of motor UVW wiring, need
to be connected in phase sequence.
Motor speed too
fast
(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.

Encoder fault
(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).
