The software MTB panel can control these features:
Feature Description
Mode Select Select either Automatic, MDI, or Manual modes as the current operating mode of the control.
Rapid Traverse This feature replaces the feedrate when executing a continuous jog move with the rapid feedrate.
Feedrate Override Selects a feedrate override percentage for feedrates programmed with an F-word, in 10% increments within a
range of 0% to 150%. When set to 0%, the control is effectively in feedhold.
Rapid Feedrate Override Selects the override for rapid feedrates. Select from F1, 25%, 50%, and 100%, where F1 is a rapid feedrate
override setting established in AMP by the system installer.
Spindle Direction Selects spindle rotation, clockwise (CW), spindle stop (OFF), or counterclockwise (CCW). Is overridden by
any programmed spindle direction command.
Spindle Speed Override Selects the override for programmed spindle speeds in 5% increments within a range of 50% to 120%.
Dry Run Mode Places the control in Dry Run Mode. This replaces feedrates with the Dry Run feedrates. See chapter 7.
Block Delete Allows the activation of the block delete feature “/ or /1”(See chapter 7). Block delete 2 -- 9 are not available
with the {FRONT PANEL}.
M-Function Lock Allows select M-, S-, T-, and B-codes to be ignored. See chapter 7.
Optional Stop This enables or disables the M01 optional stop code. When this feature is “ON,”an M01 in a part program
stops automatic execution. When this feature is “OFF,”an M01 in a part program is ignored. See chapter 10
for details on M01.
Single Block The control executes or checks one block of a part program or MDI entry each time the
button is pressed when this feature is on.
Mirror Image Mirrors the axis commands in the part program around the selected axis. See chapter 14.
Axis Inhibit Prevents axis commands from being executed. The control simulates axis motion on inhibited axes by using
Acc/Dec and feedrates; however, no actual axis motion for the inhibited axes is generated. See chapter 7.
Jog the Axes Allows manual motions to be performed in any one of the jogging modes. See section 4.1. Multi-axis jogs
may not be performed by using the Software MTB feature.
Set Zero Change the tool’s current position in the work coordinate system to 0 for the selected axis. This is done by
shifting the work coordinate system. See chapter 11.
Block Retrace This allows up to 15 part program blocks to be retraced during program execution and allow the tool to
automatically re-execute these blocks. See chapter 7.
Jog Retract Allow the tool to be manually jogged away from the part and then automatically return the tool to the part by
retracing the jogged moves. Up to 15 jog moves can be remembered. See chapter 7.
Cycle Start The control begins or resumes part program execution, MDI program execution, or program check when you
press this button.
Cycle Stop The control stops part program execution, or program check when you press this button. If pressed during the
execution of a program block, a cycle suspend state occurs.
