Home to Sensor

The Home to Sensor profile acts much like the Home to Marker profile, but instead of using the Encoder Marker as a
reference, an external sensor mounted to the machine is used as the reference. In a Home to Sensor routine, the motor
accelerates to the Home Velocity. The motor continues at the Home Velocity until the external sensor activates. Once this
sensor activates, the motor immediately decelerates to a stop, or continues for a specified offset distance before stopping.
Figures 38 and 39 show examples of the Home to Sensor profile, with calculated offset and specified offset respectively.
