Referencing the Z Pulse
This homing method uses the motor marker pulse (Z) to set the
HomingPosition. The marker pulse is on the motor encoder and occurs once
per motor rotation.

Homing Method - IO Mode Homing Method - Description
18
Look for Z pulse in forward direction and regard it as homing origin, Shows error
when encounter limit.
19
Look for Z pulse in forward direction and regard it as homing origin, Reverse
direction when encounter limit.
20
Look for Z pulse in reverse direction and regard it as homing origin, Shows error
when encounter limit.
21
Look for Z pulse in reverse direction and regard it as homing origin, Reverse
direction when encounter limit.
