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
<CYCLE START>
button is pressed when single block is active.
AXIS/DIRECTION These buttons are used for manual operations. They select an axis and direction when
<JOG SELECT>
is set for continuous, incremental, or home. If <JOG SELECT> 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 <CYCLE START>. 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.
