be considered improper
selection of the motor.)
Mechanisms are
impacted, suddenly
weighted and distorted.
Eliminate mechanical distortion.
Reduce load
Motor action when
motor brake is not
opened
Measure the voltage of the brake
terminal and decide to open the
brake.
It is suggested to use servo BK
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.
Wrong wiring of
encoder cable, power
cable or broken wire or
loose pin of connector
plug
Check the UVW connection of
power cable to see if there is any
phase sequence error.
The multimeter is used to measure
whether all the encoder cable are
on. Check whether the plug is loose,
for machine vibration, whether the
plug has shrinkage pin, virtual
welding, damage.
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.
