Caution
• Switching of damping controls will be done on the rising edge of the command whose number of
pulses/0.125 ms has been changed from 0 while the positioning complete signal is being output.
When the damping frequency is increased or disabled, and positioning complete range is large, and
pulses are stored in the filter at that time (the area represented by the value of position command before
filter subtracted by the value of position command after filter and integrated with the time). Note that since
these pulses will be discharged at a higher rate upon switching to return back to the original position, the
motor may run at a speed higher than the command speed for a short time.
