Modes 33 and 34: Homing to zero pulse
With modes 33 and 34, the direction of homing is negative or positive. The zero position
refers to the first zero pulse of the angle encoder in search direction.

Mode −1: Negative limit stop with zero pulse evaluation
With this mode, the drive traverses in negative direction until reaching the limit stop. The
931E/K servo positioning controller needs at least 1 second to detect the limit stop. When
selecting the limit stop, ensure that it will not be damaged when the maximum current
parameterised will be applied. The zero position refers to the first zero pulse of the angle
encoder in positive direction from the limit stop.
