[Pr.434] Speed change gear
Set the arrangement for the speed change gear.
0: No speed change gear ........................... Speed change is not processed, and the input
1: Main shaft side ....................................... Speed change is processed for input value
2: Auxiliary shaft side .................................. Speed change is processed for input value
3: After composite auxiliary shaft gear ....... Speed change is processed for input value
[Pr.435] Speed change gear smoothing time constant
Set the averaging time to execute a smoothing process for the speed change for the speed
change gear.
The input response is delayed depending on the time set in the speed change gear
smoothing time constant.
Speed is changed directly when "0" is set.
