OPERATION
EMERGENCY S TOP S WITCH
The EMERGENCY STOP switch is normally closed. If the switch opens or is broken, power to the servos will
be removed instantly. This will also shut off the tool changer, spindle drive, and coolant pump. The EMER-
GENCY STOP switch will shut down motion even if the switch opens for as little 0.005 seconds.
Be careful of the fact that Parameter 57 contains a status switch that, if set, will cause the control to be
powered down when EMERGENCY STOP is pressed.
You should not normally stop a tool change with EMERGENCY STOP as this will leave the tool changer in an
abnormal position that takes special action to correct.
Note the tool changer alarms can be easily corrected by first correcting any mechanical problem, pressing
RESET until the alarms are clear, selecting ZERO RETURN mode, and selecting AUTO ALL AXES.
If the shuttle should become jammed, the control will automatically come to an alarm state. To correct this,
push the EMERGENCY STOP button and remove the cause of the jam. Push the RESET key to clear any
alarms. Push the ZERO RETURN and the AUTO ALL AXES keys to reset the Z-axis and tool changer. Never
put your hands near the tool changer when powered unless the EMERGENCY STOP button is pressed.
WORK B EACONS
The red and green work beacons located directly on top of the control arm allow the operator to monitor the
machine status.
While a program is running normally, the GREEN beacon will be on.
The beacon will flash GREEN if: - the operator selects FEEDHOLD or SINGLE BLOCK stop.
- the control is in a M00, M01, M02, M30. It will stop flashing when
RESET is pressed. If the control is in an M02 or M30, and door
hold overide is not on, the beacon will stop flashing when the door
is opened.
The beacon will flash RED if: - the control encounters an alarm, such as when EMERGENCY
STOP is pressed. It will stop flashing when RESET is pressed
to clear all alarms.
