Chapter 4 Synchronous Control

[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

Pr.436

Speed change ratio:

Numerator

Pr.437

Speed change ratio: Denominator

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.
