Gain switching function
You can switch gains with the function. You can switch gains during rotation and during stop, and can use a control command
from a controller to switch gains during operation.
Applications
The following shows when you use the function.
• You want to increase the gains during servo-lock but decrease the gains to reduce noise during rotation.
• You want to increase the gains during settling to shorten the stop settling time.
• You want to change the gains using a control command from a controller 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).
