7.2 Gain switching function
You can switch gains with the function. You can switch gains during rotation and during stop, and can use
an input device to switch gains during operation.
7.2.1 Applications
T The following shows when you use the function.
(1) You want to increase the gains during servo-lock but decrease the gains to reduce noise during
rotation.
(2) You want to increase the gains during settling to shorten the stop settling time.
(3) You want to change the gains using an input device to ensure stability of the servo system since the
load to motor inertia ratio varies greatly during a stop (e.g. a large load is mounted on a carrier).
