HOME AXIS

Definition

This block locates the home position within the positioning range. This block moves the
servo in search of the home input at a motion profile as specified by the properties of this
block. The home input can be either physical or virtual, meaning the home input can be
forced on by using a bit type variable. This is useful when homing only to the “C”
channel is required. If a timeout value is specified, the program counter advances to the
block connected to the false port if the home routine has not been completed or the
timeout value has elapsed.
