8. HOW TO USE INDEXER

8.5.2 Digital override

Setting [Pr. PT38] to "_ _ 1 _" enables the digital override function.
The actual servo motor speed is obtained by multiplying the command speed by the digital override value
selected by bits 3 to 6 (C_OV0 to C_OV3) of Control DI8 (2D08h). This is enabled with all the operation
modes.
