Correction
Perform the following corrections
accordingly.
• Increase the set value of the
acceleration/deceleration time
and the stop time.
• Lighten the load.
• Adjust the gain or inertia ratio.
• If torque waveforms oscillate
excessively, adjust the system
by the tuning so that the oscilla-
tion does not occur.
• Set the appropriate brake timing.
• Increase the capacities of the
Servo Drive and the motor.
• Connect the motor cable as
shown in the wiring diagram. If
the cable is broken, replace it.
Or, connect the motor cable and
encoder cable that are used
together to the same motor.
• Measure the voltage at the
brake terminal. If the brake is
applied, release it.
Check machine conditions and
remove the cause of the friction.

Prevention
Check the items given for correc-
tions in advance and take counter-
measures as required.
Connect the motor cable as shown
in the wiring diagram. Connect the
motor cable and encoder
cable/external encoder cable that
are used together to the same
motor.
Take countermeasures so that
machine distortion is not gener-
ated.
