General Mach Discussion / Closed loop control using encoders?
« on: September 09, 2010, 03:45:22 PM »
I have read quite a bit and from what I understand Mach 3 uses encoders to update its DRO's.  But these encoder DRO's are seperate from the internal DRO's mach3 calculates from sending motor step pulses.  If Mach3 sees there is an error between the encoder DRO and the internal step pulse DRO it will feedhold and allow you to use the encoder DRO to update the step pulse DRO.  Is this correct?

Is there a way for Mach3 to use the encoder DRO only for positioning so it would be true closed loop control?
