Search for reference switch In this reference travel method, the drive moves at first at
search speed in a negative or positive direction until it
reaches the limit switch. Then it moves back at creeping
speed: The reference position lies at the point at which the
reference switch becomes inactive again when the drive
moves back.

If the drive stands on the reference switch at the start of
reference travel, it will move in the opposite direction to the
reference switch. The drive then moves as usual to the axis
zero point.
