Chapter 8 Motion Control Function
8.3.2 Auxiliary Function of Control
1. Hardware high/low limit
(1) It is used to make a sudden stop of servo drive before reaching lower limit/upper limit of the machine side by
installing high/low limit switch in the inside of the high/low limit, the physical operating range of the machine side. In this
case, the range is out of the upper limit, error ‘0x1200’ occurs, and lower limit, error ‘0x1201’.
(2) Input of hardware high/low limit switch is connected to each servo drive, and operation is stopped by servo drive at the
time of high/low limit detection, and module immediately terminates the motion which is currently being operated.
(3) In case of the stop due to the detection of hardware high/low limit signals, it is required to move inside the controllable
range of motion control module with jog operation of the opposite direction of the detected signals.
(4) Hardware high/low limit motions are as follows.
