< Jitter compensation (Vibration control when motor is stopped.) >
The load inertia becomes much smaller than usual if the motor position enters the machine backlash when the
motor is stopped. Because this means that an extremely large VGN1 is set for the load inertia, vibration may occur.
Jitter compensation can suppress the vibration that occurs at the motor stop by ignoring the backlash amount of
speed feedback pulses when the speed feedback polarity changes.
Increase the number of ignored pulses by one pulse at a time, and set a value at which the vibration can be
suppressed. (Because the position feedback is controlled normally, there is no worry of positional deviation.)
When jitter compensation is set to an axis that is not vibrating is set, vibration could be induced, so take care.
