Speed change gear parameters

Symbol Setting item Setting details
Pr.434 Speed change Set the arrangement for the
gear 1 speed change gear 1.
Pr.435 Speed change Set the smoothing time
gear 1 smoothing constant for the speed
time constant change gear 1.
Pr.436 Speed change Set the numerator for the
ratio 1: speed change ratio 1.
Numerator
Pr.437 Speed change Set the denominator for the
ratio 1: speed change ratio 1.
Denominator
Pr.490 Speed change Set the arrangement for the
gear 2 speed change gear 2.
Pr.491 Speed change Set the smoothing time
gear 2 smoothing constant for the speed
time constant change gear 2.
Pr.492 Speed change Set the numerator for the
ratio 2: speed change ratio 2.
Numerator
Pr.493 Speed change Set the denominator for the
ratio 2: speed change ratio 2.
Denominator
[Pr.434] Speed change gear 1 (R: D42686+160n/Q: D15046+150n)
Set the arrangement for the speed change gear 1. The speed change gear 1 and speed change gear 2 cannot be set in the
same arrangement. If they are set in the same arrangement, the minor error (error code: 1C08H) occurs and the synchronous
control cannot be started.
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 1 smoothing time constant (R: D42687+160n/Q:
D15047+150n)
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 corresponding the speed change gear smoothing time constant.
Speed is changed directly when "0" is set.
Setting value
0: No speed change gear
1: Main shaft side
2: Auxiliary shaft side
3: After composite auxiliary

Description
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.
