(2) Digital override
Setting [Pr. PT38] to "_ _ 1 _" enables the digital override function.
Actual servo motor speed will be 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.
Example) [Pr. PT42]: 50, [Pr. PT43]: 5
100 [%] of parameter setting speed
50 [%] of parameter setting speed
55 [%] of parameter setting speed
60 [%] of parameter setting speed
110 [%] of parameter setting speed
115 [%] of parameter setting speed
0 [%] of parameter setting speed
(a) When [Pr. PT42] is set to 50 and [Pr. PT43] to 5 in the automatic operation mode 1 (Rotation
direction specifying indexer), the chart will be as follows.
