OPERATION
STOPPING A UTOMATIC O PERATION
There are several ways a program can be stopped. They include both normal stops and abnormal, or alarm
caused, stops. The normal stops are:
1) Normal completion at M00, M01, M02, or M30.
2) A FEED HOLD stop by the operator. The program is continued by pressing CYCLE START again.
3) A SINGLE BLOCK stop when operator selected. The program is continued by pressing CYCLE
START again.
4) Door Hold stop caused by operator opening the enclosure doors. The program continues when the
doors are closed.
The abnormal stops are:
1) Operator Reset
This stops all axesîš’ motion, stops the tool changer, turns off the spindle, and turns off the coolant
pump. Program operation cannot be continued from the stopping point. If Setting 31 is On, the
program pointer is reset to the beginning.
2) Emergency Stop
This stops all axesîš’ motion, disables the servos, stops the tool changer, turns off the spindle, and
turns off the coolant pump. Program operation cannot be continued from the stopping point. This
will also stop any auxiliary axesîš’ motion. RESET must be used at least twice to remove the alarms
and start again.
3) Alarm condition
This can occur any time an alarm comes on during program operation. Since a program cannot be
restarted until RESET is pressed, a program execution cannot be continued from the stopping
point. Alarms can be caused by programming errors or machine faults. Use the Graphics simula-
tion mode to test your program first for errors.
4) Power-off
This will stop all motors within one second but does not guarantee any conditions when the
machine is powered-on again.
