Motion in Controllogix using MDAC

[MrQ]

Hello All,

I am working on motion in Controllogix.

I am going to sync two axis and was thinking of using MDAC. I enter master axis and slave axis.

Do I need to use two MAM or only one for the Master axis?

How to set limits for lag error between the two axis and how to detect it?

Program yourself a couple of virtual axes and use a spare processor or the emulator to work out how to use the instruction

Command follows closer than actual so the "Lag" is now down to the response of the servo
