Operational Overview
Figure 51: Back Off Sensor Example
Figure 52: Back Off Sensor
In the figure on the previous page, the motor has restricted travel. In order to find the rising edge of the Home Sensor input,
the motor must back away from the sensor until the Home Sensor Input Function deactivates, then move forward looking for
the rising edge of the sensor. When backing-off of the sensor, the motor will move in the opposite direction of the Home
Velocity.
