NOTE: EDIT and LIST PROGRAM can also act as display keys, where you can access program editors and the device manager without changing the machine mode. For example, while the machine runs a program, you can use the device manager (LIST PROGRAM) or background editor (EDIT) without stopping the program.

Name Key Function

Override Keys

Overrides let you temporarily adjust the speeds and feeds in your program. For example, you can slow down rapids while you prove out a program, or adjust the feedrate to experiment with its effect on part finish, etc.

You can use Settings 19, 20, and 21 to disable the feedrate, spindle, and rapid overrides, respectively.

FEED HOLD acts as an override that stops rapid and feed moves when you press it. FEED HOLD also stops tool changes and part timers, but not tapping cycles or dwell timers.

Press CYCLE START to continue after a FEED HOLD. When the Setup Mode key is unlocked, the door switch on the enclosure also has a similar result but displays Door Hold when the door is opened. When the door is closed, the control is in Feed Hold and CYCLE START must be pressed to continue. Door Hold and FEED HOLD do not stop any auxiliary axes.

You can override the standard coolant setting by pressing COOLANT. The coolant pump remains either on or off until the next M-code or operator action (see Setting 32).

Use Settings 83, 87, and 88 to have M30 and M06 commands, or RESET, respectively, change overridden values back to their defaults.

Name Key Function
-10% Feedrate [-10% FEEDRATE] Decreases the current feedrate by 10%.
100% Feedrate [100% FEEDRATE] Sets an overridden feedrate back to the programmed feed rate.
+10% Feedrate [+10% FEEDRATE] Increases the current feedrate by 10%.
Handle Control Feed Rate [HANDLE FEED] Lets you use the jog handle to adjust the feedrate in 1% increments.
-10% Spindle [-10% SPINDLE] Decreases the current spindle speed by 10%
100% Spindle [100% SPINDLE] Sets the overridden spindle speed back to the programmed speed.
+10% Spindle [+10% SPINDLE] Increases the current spindle speed by 10%.
Handle Spindle [HANDLE SPINDLE] Lets you use the jog handle to adjust the spindle speed in 1% increments.
Forward [FWD] Starts the spindle in the clockwise direction.
Stop [STOP] Stops the spindle.
Reverse [REV] Starts the spindle in the counterclockwise direction.
Rapids [5% RAPID]/ [25% RAPID]/ [50% RAPID] / [100% RAPID] Limits machine rapids to the value on the key.
