Use the Motion Axis Home (MAH) instruction to home an axis. Two different 
homing modes can be selected during axis configuration: Active or Passive. If an 
Active homing sequence is selected, the axis executes the configured Home 
Sequence Type and establishes an absolute axis position. If Passive homing is 
selected, however, no specific homing sequence is executed and the axis is left 
waiting for the next marker pulse to establish the home position.
