6. Select the Teach Tool.
7. Select (double click) on the necessary tool.
8. Set the Path Speed.
9. Set the Tool On to “Wait” or “Distance” and set the time or distance.
10. Set the Tool Off to “Wait” or “Distance” and set the time or distance.
11. Set the Line Spacing.
12. Select “Done” to save the changes, or “Cancel” to exit and not save changes.
Important Reminders
• To Insert Code – When PathMaster® programming functions are used to insert code,
the code is inserted above the current highlighted location on the screen. The
operator must make sure the new path is put in the correct position.
• To Insert Tool Functions – Commands to move the tools are NOT automatically
inserted into the path programs. If a tool must change position (up/down, rotary)
the correct function must be inserted manually with the Tool programming
function. Refer Section 2.9.
• To Download Files – The operator must activate the EMERGENCY STOP button when
downloading files to the controller.

Workcell Interaction
For PathMaster® to operate correctly it must work with the workcell. The workcell must be
in Manual mode to teach a path program online with PathMaster®. Refer to the workcell
manual for more information.
NOTE: Playback of a path is only possible if workcell is in Manual mode.
Teach Pendant
PVA workcells come with a teach pendant. Each teach pendant has a Trackball, Teach
button, Purge button, Axis selection button, and LED indicators for selected axes and
teach function.
Figure 69: Teach Pendant
LED’s – The X, Y, Z and W LED’s show the selected axis configuration. The Teach LED shows
a position was correctly recorded by PathMaster®. The light tower buzzer will “beep” when
the Teach LED illuminates.
NOTE: W-axis trackball control is locked if the Teach Tool is enabled, unless the PathMaster
Tool Offset window is open (Setup-> Machine Parameters-> “Tool Offsets”). This so the
operator does not teach an accidental theta position with the teach tool.

Fiducial Function
NOTE: When you work with fiducials, the workpiece is usually a PCB and will be referred to
as a PCB in this section and its sub sections (Section 9).
PathMaster® uses fiducials to make sure the part that is dispensed on is correctly installed
in the work area. A fiducial is an object in the field of view of the imaging system used as a
reference point. The shape and size of the fiducials must obey the SMEMA Fiducial Mark
Standard (Standard 3.1). You must have PVA Portal Vision Module 1.04 or higher, and
Firmware D220S36S or higher for the motion controller to use the fiducial functions in
PathMaster®.
The fiducial function will do an inspection of fiducial A or B to correct for the translational
(X and Y) and rotational offset (skew) of a product. To correct for skew, the product must
have an A and B fiducial mark and the skew must be within an acceptable tolerance. The A
and B fiducials should be located diagonally opposite one another.
The skew tolerance is set in the inspection program profile from the Portal Manual teach
window. The tolerance is a radius in millimeters from the center of the expected fiducial
location. The measured center of the fiducial must fall within this radius to pass the check.
Refer to the Portal Manual.
Program and run fiducial A before fiducial B.
Figure 70: Example Fiducial
Fiducial A
When fiducial A runs, X and Y offsets are cleared, and the tool moves to the taught
absolute gantry position. When the tool is in position, the programmed fiducial parameters
are run. A pass / fail status is shown. If the result is a pass, an XY offset is reported to the
controller.
NOTE: There is a box so the XY offsets are not cleared when fiducial A is run. Do not select
this box unless there is a reason.
