    Each limit switch sends its signal to the controller on a dedicated line. The controller then interrupts the motion avoiding that the positioner moves until the hard stop and gets damaged. PI positioners have mechanical, noncontact optical or Hall effect limit switches. Load Capacity Maximum load in the vertical direction when the L-812.xx1400 is mounted horizontally.
