Operation
3. CNC power supply should be cut off firstly, and then the machine power supply is cut off.
Note: 1. Turn on the power, again after power off for 20 seconds.
2. About the operation of cutting the machine power supply, please refer to the user manual from the
machine manufacturer.
2.3 Overtravel Protection
To avoid the machine damage due to the each axis overtravel, the machine must be adopted the
overtravel protection measures.
The limit switches should be respectively installed on the maximum stroke position in the positive
and negative directions of each axis on the machine. When the overtravel occurs, the limit switch is
operated, the system decelerates till stops, and the overtravel alarm occurs.
During automatic running, when one axis is touched the limit switch, all axes along which the
tools are being moved should be decelerated and stopped, and the overtravel alarm occurs.
During manual operation, just the axis in which the tool touching the limit switch is decelerated
and stopped, the tool is still moved along other axis.
The method of clearing “the overtravel” is: In manual mode, the worktable is moved reversely
(like the positive overtravel, it is moved negatively, vise versa), and moved away from the limit switch.
The system resets and issues the alarm.
Note: The method of the releasing the machine overtravel is different with that introduced in the manual;
about the detailed operation, please refer to the user manual of the machine manufacturer.
2.4 Overtravel Protection of Stored Stroke
GSK988TA system provides three stored stroke check areas: The areas in which the tools can’t
enter can be specified as the stored stroke check 1, the stored stroke check 2 and the stored stroke
check 3, which is shown in Fig.2-3:
Fig.2-3
When the tool exceeds a stored stroke limit, an alarm is displayed and the tool is decelerated
and stopped. When the tool enters a forbidden area and an alarm is generated, the tool can be
