I must be doing something wrong, but cant for the life of me see what. Any hints would be welcomed.
How the hell do I stop a rotary drive going backwards using RSLogix V11 and (for this example) a MAM instruction.
If at position 0.5 (and stationary) and request move to 0.25 I want the drive to travel +0.75 and not -0.25 revs. Surely not too much to ask.
The actual problem is I want to stop at a preferred position, depending on what speed and deceleration I have, and the phase I detect the request to stop the system may or may not go backward.
