• With the 2nd gain switching function enabled, you can provide
phased switching time only for position loop gain when gain is
switched.
• Switching time is only provided when a small position loop gain is
switched to a large position loop gain (Kp1 → Kp2) (in order to
alleviate impact to the machine due to abrupt change in gain).
• Set a value that is smaller than a difference between Kp2 and Kp1.
