Mode −2: Positive limit stop with zero pulse evaluation
With this mode, the drive traverses in positive direction until reaching the limit stop. The
931E 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 negative direction from the limit stop.

Mode −17: Homing to the negative limit stop
With this mode, the drive traverses in negative direction until reaching the limit stop. The
931E 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 directly refers to the limit stop.
