4.3 Emergency Stop and Limit
The system is with the software limit function. For safety, the hardware limit measure should be
adopted meanwhile, and the limit switches of each axis in positive and negative directions should be
installed.
About GSK980TC3 integration system, the user can monitor and check the state of the
emergency stop input signal through checking NO ： 009#4 （
*
ESP ） on 【 X signal 】 software interface
of the <diagnosis> interface. After pressing the emergency stop button, all the air switches of the
system must be OFF.
In JOG or MPG mode, each coordinate axis is moved slowly to testify the validity of each axis
overrun limit switch, the overrun release button and the correctness of alarm display. The system
alarms when the overrun occurs or the emergency stop button is pressed; while press the overrun
release button and the axis moves oppositely, the system can release the alarm.

It’s required to correctly display the alarm “some axis (the 1
st
axis or the 2
nd
or the 3
rd
axis) in
some direction (positive or negative) when the servo axis overruns. And it guarantees that after the
overrun is released, the axis can’t move in the overtravel direction when some axis overruns and the
alarm occurs. Therefore, GSK980TC3 system provides two connection methods of overrun limit
switches to satisfy the customers’ requirements.
A. The situations of two limit switches:
(One limit switch of some axis in the positive direction, the other is in the negative)
