Emergency operation
During the processing, due to user programming, operation and product failures, certain
unexpected events may occur. At this moment, please stop the system immediately. This section
involves the treatment that the system can perform under emergency conditions. Please refer to the
instructions of machine tool for the treatment that the machine tool can perform under emergency
conditions.

Reset
When the system output or coordinates action is abnormal, press the Reset
key to reset the
system:
1. The motion of all axes stops;
2. M, S function output is invalid (it is possible to set whether disable main axis
positive/negative rotation, lubricant and cooling signals automatically after pressing the
Reset key
);
3. Automatic running stops, and mode function and state maintain.
2.5
Emergency stop
When the machine tool is running, press the Emergency stop button (when external emergency
stop signal is valid) if there is any danger or emergency, and the system will enter the emergency
stop state immediately. At this moment, the machine tool stops moving immediately, and all
outputs (e.g. rotation of main axis, cooling liquid, etc.) are off. Release the button to relieve the
alarm, and then the system enters reset state.
Note 1: Please make sure that the failure has been eliminated before relieving the alarm;
Note 2: Before turning on/off the machine, press the emergency stop button to reduce the electric
impact to the equipment;
Note 3: After relieving the alarm, please re-execute the mechanical reset operation to ensure the
accuracy of the coordinates (if the machine tool doesn’t have mechanical origin, do not perform this
operation);
The emergency stop function is controlled by system parameters ---- emergency stop function. The
function is valid only when the value is set to 1.
The level of emergency stop signal is controlled and set by system parameters ---- emergency stop
signal level.
