In
multiple
mechanical
wirings,
incorrect
connection
of motor cable to
other shafts leads to
incorrect wiring.
Detection of servo wiring, the
motor cable, encoder cable are
correctly
connected
to
the
corresponding shaft.
Poor gain adjustment
results
in
motor
vibration, back and
forth
swing
and
abnormal noise.
Readjustment of gain parameters
Driver
or
motor
hardware failure;
There are servo cross test or motor
empty shaft on site, F1-01 trial
operation, F1-00 jog run can not
rotate uniformly;
Replace the new driver or motor
and send the malfunction machine
back to the manufacturer for repair.

(1)
Eliminate
the
factors
of
mechanical distortion. Reduce load
(2) Measure the voltage of the brake
terminal and determine the opening
of the brake;
It is suggested to use servo BK
brake signal to control the brake
lock. If it is not servo control,
attention must be paid to the timing
of brake opening and motor action.
(3) Monitor the actual output torque
range of U0-02 and check whether
the setting of P3-28/29 torque limit
is reasonable. (After version 3760,
the output torque limit setting
parameters of anti locked rotor
alarm are P3-38 and P3-39

The value of servo DC + DC -
incoming line is measured by DC
gear of multimeter, and the normal
value is 48V. If the power supply
voltage is normal, monitor U0-05 in
servo bb state, the voltage measured
by multimeter ˃ U0-05, the servo
driver is faulty and needs to be sent
back for maintenance.
