Numerator
[Pr.437] • Set the denominator for the speed change
Speed change ratio: ratio.
Denominator Fetch cycle: Operation cycle
[Pr.434] Speed change gear
Set the arrangement for the speed change gear.
Setting value
0: No speed change gear
1: Main shaft side
2: Auxiliary shaft side
3: After composite auxiliary shaft
gear
[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.
[Pr.436] Speed change ratio: Numerator, [Pr.437] Speed change ratio: Denominator
Set the numerator and the denominator for the speed change ratio.
"[Pr.436] Speed change ratio: Numerator" and "[Pr.437] Speed change ratio: Denominator" can be changed during
synchronous control.
Input values for speed change are processed as follows.
Input value after change = Input value before change X
The input speed can be reversed by setting a negative value in " [Pr.436] Speed change ratio: Numerator".
"[Pr.437] Speed change ratio: Denominator" is set within the range from 1 to 2147483647.

Details
Speed change is not processed, and the input value is transmitted as is.
Speed change is processed for input value after main shaft clutch based on the speed change ratio settings.
Speed change is processed for input value after auxiliary shaft clutch based on the speed change ratio settings.
Speed change is processed for input value after composite auxiliary shaft gear based on the speed change ratio
settings.
