Speed Change Gear Module

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 gear1 (R: D42686+160n/Q: D15046+150n)" and "[Pr.490] Speed change gear2 (R: D42692+160n/Q:
D15052+150n)".
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.
