(2) Digital override
Setting [Pr. PT38] to "_ _ 1 _" enables the digital override function.
Actual servo motor speed is the value multiplying the command speed by the digital override selected
with OV0 (Digital override selection 1) to OV3 (Digital override selection 4). This is enabled with all the
operation modes.
