Functions of the Buttons on the Push-Button MTB Panel
Switch or Button Name = Default for Push-Button MTB Panel How It Works
CYCLE STOP The control stops part program execution, MDI execution, or program check when this button is
pressed. If pressed during the execution of a program block a cycle suspend state occurs.
SINGLE BLOCK The control executes or checks one block of a part program or MDI entry each time the
button is pressed when single block is active.
AXIS/DIRECTION These buttons are used for manual operations. They select an axis and direction when
is set for continuous, incremental, or home. If is set for
handwheel, these buttons select an axis only. Direction is then determined by handwheel rotation.
TRVRS Hold this button down while executing a continuous jog move to override the active feedrate and jog an
axis in rapid traverse.
F1 - F4 The functions for these buttons are assigned by the system installer. Refer to the documentation
prepared by the system installer for details.
JOG RETRACT Use jog retract to jog a cutting tool away from the workpiece during automatic or MDI program
execution. The control can retrace the jog moves and return the cutting tool automatically to the
workpiece by pressing . Refer to page 7-28 for more on this.
BLOCK RETRACE To retrace the tool path in a part program already executed (up to 15 blocks), press this button.
ON Turns on power to the control.
OFF Turns off power to the control.
Important: Many of the override switch settings may be disabled by
programming the correct M-code or setting a particular paramacro
parameter. Refer to their respective sections for details on these features.
The 9/Series control offers a software MTB panel that performs many of
the functions of an MTB panel. This feature uses softkeys instead of the
normal switches and buttons of a panel. If the control uses a push-button
MTB panel (described on page 2-10), or some other custom panel, the
requests for operations from the panel takes priority. This means that
requests of the software MTB panel are ignored if another request is sent
from a push-button MTB panel or a custom MTB panel.
The software MTB panel’s operation depends on PAL, especially if the
control uses a push-button MTB panel or a custom MTB panel. Refer to
documentation prepared by your system installer for details on using the
software MTB panel. Your system installer uses PAL to disable the

softkey.
Important: By using the PAL flags $SWF1 and $SWF2, you can enable
and disable features available on the software front panel. Refer to your
PAL reference manual for additional information.
