4-82 System Configuration and Setup
Table 4-13 Setup Vision Options
Command Description
Hardware
Vision System
: Indicates the type of Vision System installed on your dispensing
system. Click on the drop-down arrow to view the available options.
Video Mixer
: Indicates the type of video processing card installed on your
computer system. Click on the drop-down arrow to view the available options.
Calibrate
: Opens a Teach Window where you are prompted to perform a step-
by-step procedure for calibrating the number of pixels in the video display to the
number of X and Y motor steps it takes the dispensing head to travel the
equivalent distance.
NOTE If the camera is replaced or adjusted in any way, the Vision System
must be recalibrated.
Setup Reticles
: Opens a Teach Window for setting up the parameters for
reticles displayed in video display screens.
Version Info
: Opens a window displaying the version of the Vision System
hardware installed on your dispensing system.
Setup Light
: Opens a window for identifying, selecting, and configuring the
lighting on your system.
Graphics Level
: When using Corner Finder to locate fiducials, this feature allows
you to regulate the amount of graphic details (i.e., calipers, search window,
found edge points) shown in the video display window during runtime. Starting
with None (which displays none of the graphics), the amount of graphic details
displayed increases until you reach the High (default) setting where all details
are displayed. Lowering the graphics level can increase throughput by reducing
the time the system takes to “paint” the graphics on the screen.
NOTE When using Model Finder to located fiducials, High displays a
search window during runtime and the other settings do not.
Configuration
: Opens the Configuration window where you can set Vision
System performance settings (for Genie camera only). See Figure 4-72.
General
Use Antibacklash Move
: Enables the Antibacklash feature. This feature is
available on Automove machines (Century Series, M-600 Series) only.
Antibacklash is a method for double-checking the dispensing head position.
When the dispensing head moves to a commanded position, the Antibacklash
feature causes it to back off a certain distance, check the commanded position
coordinates, and then move back into position. To change Antibacklash
parameters, select Configuration > Setup Dispenser > Personality
Parameters in the Main Window.
Tolerances
Fid Location Tolerance
: Defines a parameter for accepting or rejecting a fiducial
based on its actual position in relation to its expected position. If the found
fiducial is not within the tolerance parameter, the operator receives a Fiducial
Error message. This feature can also be used to check for chip placement
accuracy.
Diagonal Distance Tolerance
: Checks to see if the fiducials are as far apart as
they are expected to be. This prevents the Vision System from choosing the
wrong fiducial. Generally, 0.1 inch is sufficient, depending on chip scribing
accuracy and chip size variations.
Orthogonality Tolerance
: This value is used with the Corner Finder method of
locating a fiducial. When a fiducial is found, FmXP checks the angle between the
two found edges to determine if the part is square. If the angle is 90 degrees
plus or minus the Orthogonality Tolerance, the part is considered to be square
and dispensing is performed. If the angle is outside of the Orthogonality
Tolerance, FmXP issues a Fiducial Error message.
