To enable the digital override function, set [Pr. PT38] to "_ _ 1 _".
This signal is for multiplying a command speed by the digital override
(multiplying factor).
A command speed multiplied by the digital override value selected with this
signal will be an actual servo motor speed.
If the servo motor speed multiplied by the digital override value exceeds
the servo motor maximum speed, the speed will be limited at the maximum
speed.
The following table shows an example of setting "50" to [Pr. PT42] and "5"
to [Pr. PT43].
