12h) Click Inspection.

12i) Verify that X = 0, Y = 0 and A = 20.

NOTE: If X or Y is more than ±5, then the vacuum cup nozzle is not

correctly positioned. Repeat Step 1 and Step 2 on page 3-21 to

reposition the vacuum cup nozzle.

12j) On the Vision System window, click Exit.

This completes the process of teaching a reference vision file.

Teach the Package File

The package file contains information about the location of all programmers,

all available input media, and the shuttle transfer (if installed). During Task

creation, you copied the PackageTemplate.txt file and renamed it to the

adapter used in the Job (see TaskLink online Help). This renamed package

file contains the Package Template values. Now it is necessary to teach the

package file for the particular device being programmed.

NOTE: If an error button appears on the Gantry window while

teaching the package file, see “Errors” on page 3-45.

To teach the package file:

Teach Programmer Locations

1. Prepare the system—

1a) From TaskLink, select and load the newly created Job.

1b) From the AH500 Setup window, select the Options tab.

1c) For main Input and Output media, select Trays.

1d) For Reject 1, select Reject Tray.

1e) By hand, open the socket on Programmer 1 and insert a device.

NOTE: If Programmer 1 contains more than one socket, insert

devices in the first and last sockets.

1f) On the AH500 Setup window, click System.

1g) On the System window, click Gantry to display a graphic representa-

tion of the work surface, including yellow position labels for all loca-

tions in the work envelope. The Gantry window also includes Y-axis

and X-axis adjustment arrows. See Figure 3-47.

WARNING: Stay clear of the operating envelope while teaching

PNP head locations. The PNP head can move without notice

when operating in this mode.

1h) Click P1. The gantry moves the PNP head to the location specified, and

a white box appears on the graphic relative to the PNP head’s physical

location. The position label flashes RED then YELLOW indicating the

position of the PNP head.

2. Adjust location of the probe tip—

2a) Adjust the location of the probe tip so that it is centered on the device.

Use the up/down arrows for Y-axis adjustments and the left/right

arrows for X-axis adjustments. From the inside working outward, the

arrow buttons adjust the position ±0.001, 0.010, and 0.100 inches

respectively. See Figure 3-47.

2b) Click Save.

NOTE: When saved, these settings are kept in the appropriate

package file (.txt) in the directory C:\AH400_32\Package on

the Handler Computer.

3. Z AutoFind—

3a) Click Z AutoFind. The PNP head lowers and the probe tip touches the

device.

3b) Click Ye s to save the new values.

The Z-axis reference position is now set. From the Z-axis reference, the

drop and pick offsets are added.

For example, if Z-axis reference = -1.000, then:

Zdrop = -0.910 and Zpick = -1.025

See Figure 3-48.

4. Adjust Socket Actuator (if required)—

NOTE: Adjust the Socket Actuator only if the socket fails to open or

if devices are dropped. It is necessary to adjust the Socket Actuator

only once while teaching a package file.

4a) Click Socket ON. This lowers the Socket Actuator and opens the

socket.

4b) On the input panel, push the main air valve down to the OFF position.
