Speed change gear parameters
n: Axis No. - 1
[Pr.434] Speed change gear
Set the arrangement for the speed change 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.
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.

Setting value Details
0: No speed change gear Speed change is not processed, and the input value is transmitted as is.
1: Main shaft side Speed change is processed for input value after main shaft clutch based on the speed change ratio settings.
2: Auxiliary shaft side Speed change is processed for input value after auxiliary shaft clutch based on the speed change ratio settings.
3: After composite auxiliary shaft
gear
Speed change is processed for input value after composite auxiliary shaft gear based on the speed change ratio
settings.
Input value after change = Input value before change ×
