Now suppose that the slave axis is engaged with a start signal, input 1, but that both the engagement and
disengagement points must be done at the center of the cycle: X = 1000 and Y = 500. This implies that Y must be
driven to that point to avoid a jump.
disengagement points must be done at the center of the cycle: X = 1000 and Y = 500. This implies that Y must be
driven to that point to avoid a jump.
This is done with the program:
