Software Position Range Limit
The Software Position Range Limit defines a Positive Position Limit and a Negative Position Limit, which act as
hardware limit switches.
The Software Position Range Limit is activated when Axis Type (0x3360) is linear.

3.2.3.4 - Homing Mode
When the feedback sensor does not give the absolute position, the homing mode is the right way to set up the
motor to a known position. This position can be detected by using several signals such as positive or negative
limit switch, home switch, index pulse or mechanical limit. The choice of the homing method depends on those
signals and on the direction of the starting movement.
The drive generates the trajectory according to the homing method. This is the reason why the position loop of the
drive is used.
