Safe operation
5.1
Emergency stop
Press the emergency stop button on the machine tool, which will stop immediately, and all outputs such as
spindle rotation and coolant are turned off. Rotate the button clockwise to cancel emergency stop, but all outputs
must be restarted.
0 Caution:
The power supply isn’t always cut off upon emergency stop. Please refer to the electrical configuration
description of the machine tool manufacturer for details;
Before releasing emergency stop, please eliminate the problems of the machine tool.
5.2
Hard limit over travel
The system alarms if the tool touches travel switch during operation. The axis in corresponding direction can’t
move, and only moves in reverse direction. Before the alarm is released, the system can’t enter automatic
operation normally. After investigating the alarm reason, press [Reset] to clear the alarm information.
5.3
Soft limit over travel
If the tool enters the restriction area regulated by the parameter (travel limit), the system alarms over travel, and
the tool decelerates and stops. At this moment, you can move the tool to safe direction in manual mode, and then
press [Reset] to release the alarm.
0 Caution:
During automatic operation, when the tool touches an axial travel switch, the tool decelerates and stops all axial
motions, and only displays one over travel alarm.
During manual operation, when the tool touches an axial travel switch, the tool only decelerates and stops
motion on current axis, and still moves along other axes.
When the tool is in safe position, press [Reset] to clear the alarm. Please refer to the manual of the machine tool
for details.
Both limit alarm and soft limit alarm have a deceleration stop, and therefore the sensing range of the limit should
have sufficient space, or else the limit protection will be disabled due to over travel.
