Here is a screenshot of the section of the Brain for that.
I am using a PLC so it says Mod ** In but if using normal inputs to Mach it would have them.
So basically it is looking at 4 inputs 23,24,25,26.
23 is the position for Velocity mode so it passes the signal to the end and outputs the MPG Mode 1 which is velocity mode.
24, 25 and 26 are passed through then through an Or and then to MPG Mode 3 which is multi step.
Also 24, 25 and 26 are looked at to set the Step size DRO, so first is a/100 so your step size would be 0.01mm, next a/10 so 0.1mm and lastly a/1 so 1mm.
