Relationship between the Waiting and Switching Times for Gain Switching
In this example, the "positioning completed signal (/COIN) ON" condition is set as condition A for automatic
gain switching. The position loop gain is switched from the value in Pn102 (position loop gain) to the value in
Pn106 (2nd position loop gain). When the /COIN signal goes ON, the switching operation begins after the
waiting time set in Pn135. The switching operation changes the position loop gain linearly from Pn102 to
Pn106 within the switching time set in Pn131.
Position Loop Gain
Note: Automatic gain switching is available in the PI and I-P controls (Pn10B).
