9.4 DSP 402 Homing Methods
The following sub-sections describe the details of how each homing mode functions. The
Elmo drives support each of these methods.
9.4.1 Method 1: Homing on the negative limit switch and
index pulse
Using this method, the initial direction of movement is leftward if the negative limit
switch is inactive (here shown as low). The home position is at the first index pulse to the
right of the position where the negative limit switch becomes inactive.

9.4.2 Method 2: Homing on the positive limit switch and
index pulse
Using this method, the initial direction of movement is rightward if the positive limit
switch is inactive (here shown as low). The position of home is at the first index pulse to
the left of the position where the positive limit switch becomes inactive.
