Gain Adjustment - Panasonic minas a4 series Instruction Manual

Gain Adjustment

Purpose
It is required for the servo driver to run the motor in least time delay and as faithful as possible against the
commands from the host controller. You can make a gain adjustment so that you can run the motor as
closely as possible to the commands and obtain the optimum performance of the machine.
