2.3 Overtravel Protection
Overtravel protection should be used to prevent machine from being damaged due to the
overtravel of X, Y, or Z.
2.3.1 Hardware overtravel protection
The stroke switches are fixed at the positive and negative maximum travel of the machine X, Z, Y
axis respectively, they are connected by the following figure. And the BIT3 of bit parameter No.172
must be set to 0. If the overtravel occurs, the stroke switch acts to make GSK980TDc stop, and the
emergency alarm is issued.
When the hardware overtravel occurs, there will be an “emergency stop” alarm in GSK980TDc.
The steps to eliminate this alarm are: press the OVERTRAVEL button to switch to the ALARM page,
view the alarm message, and reset the alarm and move the table reversely to detach the stroke
switch (for positive overtravel, move negatively; vice versa) .
2.3.2 Software Overtravel Protection
When the Bit4 of bit parameter No.172 is set to 0, the software limit is active.
1. X, Z axis
The software strokes are set by data parameter No.045, No.046, they refer to the machine
coordinates. As follows figure shows, X, Z are the machine coordinate system axes; No.045 is for X
axis positive and negative strokes, No.046 is for Z axis positive and negative strokes, within the
broken line is the software stroke scope.
If the machine position (coordinate) exceeds the area within broken line, overtravel alarm will be
issued. The steps to eliminate this alarm are: press the overtravel alarm release key to clear the
