Operation
When hardware overtravel appears, “Emergency stop” alarm of GSK980MDc occurs. Releasing
“Emergency stop” alarm: press the overtravel release button, move the worktable reversely (when the
positive overtravel occurs, the worktable is moved negatively, and vice verse.) to break away from the
travel switch.
2.3.2 Software overtravel protection
When No. 0172 MOT is set to 0, the software limit function is valid;
Software travel range is set by
№
045
~
№
046, and is taken machine coordinates as reference values.
No.045 is max. positive travel of X, Y, Z, 4
th
, 5
th
axis, and No. 046 is max. negative travel of X, Y, Z, 4
th
, 5
th
axis.
When the machine position(machine coordinates) exceeds the set range, the overtravel alarm occurs.
Releasing overtravel alarm: press the reset key, clear the alarm display, and move reversely the worktable
(when the positive overtravel occurs, the worktable is moved negatively, and vice verse.)
2.4 Emergence Operation
During the processing, due to the user programming, operation and the product default, etc, some
unexpected situations may occur, then, GSK980MDc should stop working immediately. In this chapter, it
mainly introduces the measures taken in emergency. About the machine in emergency, refer to the relative
introduction of the machine manufacturer.
2.4.1
Reset
When GSK980MDc output and the coordinate axis moves abnormally,
is pressed to reset
GSK980MDc:
1. All axes movement stops;
2. Function of M and S output invalid(
The parameter sets whether the system automatically closes the spindle
CW/CCW, the lubricating, the cooling signal after
is pressed
);
3. Auto running completes, mode function and state hold.
2.4.2 Emergency stop
During the machine running, in the dangerous or the emergency situation, press the emergency stop
button and the external emergency stop signal is valid, and then CNC works in the emergency situation and
the machine stops moving at once, all output is off, such as the revolving of the spindle and the cooling fluid.
After releasing the emergency stop button, the alarm is released, CNC resets. The circuit connection
method is referred to Section 2.2.1.
Note 1: Before releasing the emergency stop alarm, confirm the trouble is resolved;
Note 2: Before power on and off, press the emergence stop button to reduce the electric shock of the equipment;
Note 3: After releasing the emergence stop alarm, return to the reference position again to ensure the precision of
the coordinate position(when the machine zero is not installed on the machine, the machine zero return
cannot be executed);
Note 4: When No.0172 MESP is set to 0, the external emergence stop is valid.
2.4.3 Feed hold
During the machine running, press
to stop the running, temporarily. Pay attention to that during
the thread cutting or the cycle command running, even press the button, the running can’t stop immediately.
