Operation
2.5 Emergency Operation
During machining, some unexpected consequence may occur due to the user programming,
operation and the product fault, GSK988TA operation must stop immediately. In this chapter, the
measures are taken by GSK988TA in emergency; about the measures taken by the CNC machine
tool, please refer to the user manual from the machine builder.
2.5.1 Reset
When GSK988TA is abnormally output and the coordinate axis is abnormally operated, pressing
key makSe GSK988TA in resetting status;
1. All axis movement is decelerated and stopped;
2. M and S function output is invalid;
3. Automatic running stops and modal function remains.
Note: After
is pressed,
whether automatically switch off the signals of the spindle
CW/CCW rotation, the lubrication and the cooling, etc. is set by the parameters.
2.5.2 Emergency Stop
During the machine running, the emergency stop button (the external emergency stop signal is
valid) is pressed in the dangerous or in the emergency situation, CNC takes the emergency stop
measures, and the machine movement is stopped immediately, all output (such as the spindle
revolution and the coolant, etc) are all switched off. The emergency stop alarm is released after
releasing the emergency stop button, CNC enters the resetting status.
Note 1: Please confirm the trouble has been removed before the emergency stop alarm is released;
Note 2: The electric shock can be reduced when the emergency stop button is pressed before power-on/off.
Note 3: After the emergency stop alarm is released, the reference position return should be executed, again to
guarantee the correctness of the coordinate position.
2.5.3 Feed hold
During the machine running, the feeding can be hold after pressing key. Please pay
attention that the function can’t stop the feeding immediately during thread cutting and the cycle code
executing.
2.5.4 Cutting off the Power Supply
During the machine running, in danger or in the emergency situation, the machine power supply
must be cut off immediately to avoid the accident. Please pay attention that the reference position
return should be executed, again if the coordinate displayed by CNC doesn’t comply with the actual
position after power off.
