Step 9. Create program to run ECAM mode
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: A = 1000 and
B = 500. This implies that B must be driven to that point to avoid a jump.
This is done with the program:
