4.4 Speed change gear module

4.4.1 Overview of speed change gear module

A speed change gear module is used to change the input speed from the main shaft/auxiliary
shaft/composite auxiliary shaft gear during operation. When not using a speed change gear
module, set "0: No speed change gear" in "[Pr.434] Speed change gear".
With speed change from a speed change gear module, operation is executed with linear
acceleration/deceleration based on the setting for the speed change gear smoothing time
constant.
