Gain Switching Function - Mitsubishi MR-JE-10A Instruction Manual

7. SPECIAL ADJUSTMENT FUNCTIONS
(2) Parameter
Set [Pr. PB45 Command notch filter] as shown below. For the command notch filter setting frequency,
set the closest value to the vibration frequency [Hz] at the load side.

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
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).
