5-4-6 Gain Adjustment  
z  The table below shows the parameters for adjusting the position loop. 
z  Two position loop gains can be selected from input contact terminals according to 
table below. 
z  For selection methods refer to section. 5-3-11.

Diagram below shows the position controller. Adjust a higher gain value can reduse 
response time.  
Position Feed-Forward Gain can also be used to shorten the positioning time.
