Homing methods 5 and 6: Negative reference cam and zero pulse

Method 5: Start movement in direction of positive (right) hardware limit switch with zero pulse

• Start movement in direction of positive (right) hardware limit switch; at this time the reference cam is active.
• First zero pulse after falling cam edge corresponds to zero/reference point.
• The direction of movement reverses on an active reference cam edge.
• Start movement in direction of negative limit switch if reference cam is inactive.

Method 5: Start movement in direction of negative (left) hardware limit switch with zero pulse

• Start movement in direction of negative (left) hardware limit switch.
• The direction of movement reverses on an inactive reference cam edge.
• First zero pulse after rising cam edge corresponds to zero/reference point.
