M-Series Operator’s Manual 4/9/15 2-3
Cycle Cancel
Press CYCLE CANCEL to abort the currently running program. The control will stop movement immediately, clear
all M-functions, and return to the Main Screen. It is recommended that you press FEED HOLD first before CYCLE
CANCEL. If you press CYCLE CANCEL, program execution will stop; if you wish to restart the program you must
rerun the entire program or use the search function. See search function operation in Chapter 3 or Chapter 6.
Emergency Stop
EMERGENCY STOP releases the power to all the axes and cancels the current job immediately upon being pressed.
EMERGENCY STOP also resets certain faults if the fault condition has been fixed or cleared.
WARNING
On some machines, vertical axes (such as Z and/or W) may start to move due to
gravity pulling it down when motor power is cut due to EMERGENCY STOP
being pressed.
Spindle CW/CCW
The SPINDLE CLOCKWISE/COUNTERCLOCKWISE keys determine the direction the spindle will turn if it is
started manually. If the spindle is started automatically, the direction keys are ignored and the spindle runs according
to the program. The default direction is CW.
Spindle Speed +
Pressing this key will increase the spindle speed by 10% of the commanded speed in Auto spindle mode, limited by the
maximum speed or 200% of commanded speed, whichever is less. For manual spindle mode, the spindle speed is
increased by 5% of the maximum spindle speed (up to the maximum speed). The LED is on if the spindle speed is set
above the 100% point.
Spindle Speed 100%
Pressing this key will set the spindle speed at the 100% point, which is defined as the commanded speed in Auto
spindle mode, or ½ the maximum spindle speed in manual mode. The LED will be on when the spindle is at the 100%
point.
Spindle Speed -
Pressing this key will decrease the spindle speed by 10% of the commanded speed in Auto spindle mode, limited to
10% of commanded speed. For manual spindle mode, the spindle speed is decreased by 5% of the maximum spindle
speed down to 5% of maximum. The LED is on if the spindle speed is set below the 100% point.
Spindle (Auto/Man)
This key selects whether the spindle will operate under program control (automatic) or under operator control
(manual). When the LED is lit, the spindle is under automatic control. If the LED is off, the spindle is under manual
control. Pressing the SPINDLE (AUTO/MAN) key will toggle it from AUTO to MAN and back again. The default
is AUTO mode.
