4.8 Gains switching
Through internal condition or external signals carry on gains switching to achieve the
following goals:
 When the servomotor is in stop condition (servo driver is locking),make a switching for low
gain in order to suppress the vibration and the incisive noise;
 When the servomotor is in stop condition, make a switching for high gain in order to enlarge
the rigidity of the servo system;
 When the servomotor is in running condition, make a switching for high gain in order to
obtain the better tracking performance and the small positioning time;
 According to the load situation, switching different gain achieves the optimizing control.
Showing below there are the first group and the second group of gain. Each group has four
parameters. The first group will switch to the second group or vice versa.
