Figure 11: Homing to the negative limit switch
Method 18: Homing to the positive limit switch
If this method is used, the drive moves in the positive direction at search speed until it reaches the
positive limit switch. In Figure 12 this is represented by the rising edge. Then the drives moves back at
crawl speed and tries to find the exact position of the limit switch. The zero position refers the falling
edge of the positive limit switch.

Methods 33 and 34: Homing to the index pulse
In the case of method 33 and method 34 the direction of the homing run is negative or positive. The
zero position refers to the first index pulse of the angle encoder in search direction.

Method -1: Negative stop with index pulse evaluation
If this method is used, the drive moves in the negative direction until is reaches the stop. The
DUET_FL servo positioning controller needs at least 1 second to recognize the stop. The mechanical
design of the stop must be such that it cannot be damaged at the parameterized maximum current.
The zero position refers the first index pulse of the angle encoder in the positive direction from the
stop.
