Homing methods 1 and 2: Limit switch and zero pulse
Method 1: Negative limit switch and zero pulse
- Start movement left; at this time the hardware limit switch is inactive.
- The direction of movement reverses on an active hardware limit switch edge.
- First zero pulse after falling limit switch edge corresponds to zero/reference point.

Method 2: Positive limit switch and zero pulse
- Start movement right; at this time the hardware limit switch is inactive.
- The direction of movement reverses on an active hardware limit switch edge.
- First zero pulse after falling limit switch edge corresponds to zero/reference point.
