Setting Up Inputs / Outputs

If you connected inputs / outputs, follow this procedure to test input / output connections.

NOTE: All automated dispensing systems provide 8 standard inputs and 8 standard outputs. A kit to expand to

16inputs and 16 outputs is available. Refer to “Accessories” on page89.

PREREQUISITES

 The system is properly installed and set up. Refer to “Installation” on page19 and “Setup” on page44.

 Input / output wiring is properly connected. Refer to “I/O Port” on page95 for wiring diagrams.

Click Step

• Click SYSTEM SETUP > IO.

• Click the outputs you want turn ON or OFF, then click the X to close the

window.

NOTES:

• Inputs ﬂash red when they are turned ON.

• Use only inputs / outputs 1 through 8. The remaining I/Os are reserved for the

system.

Configuring Input / Outputs for a Special Purpose

The IO Pin Function feature provides a set of user-conﬁgurable conditions that affect the operation of the robot.

Refer to “AppendixG, I/O Pin Function Setup” on page146.

Item Function

Absent Speciﬁes how the system responds when it is unable to recognize a mark.

NOTE: You can assign a speciﬁc Absent selection to any saved image in the Mark Library.

Parameter Description

Skip The robot skips to the next program address.

Stop The robot stops.

Pause The robot pauses.

Ask The system asks if you want to: Find Again, Find Next, Stop Find, or use the

Manual mode.

Manual The system asks you to jog the camera to the center of the mark yourself, then to

select CONTINUE to continue the program.

Score Speciﬁes how accurately the camera ﬁnds a mark based on a value from 0.1 to 1. A higher value

results in more precise matching. A lower value results in less precise matching.

NOTE: You can assign a speciﬁc Score value to any saved image in the Mark Library.

Delay(s) Sets how the long system delays (in seconds) searching for a mark when it reaches the mark area.

Sense Speciﬁes how accurately the camera aligns with the pixels of a mark based on a value from 1 to

200. When the Sense value is low, the camera is slower to align with the mark because it repeatedly

checks the position of the mark to achieve high accuracy. When the Sense value is higher, the

camera aligns with the mark faster, but with less accuracy. For example, a Sense value of 1 means

the deviation cannot be more than one pixel. When the Sense value is 200, the deviation can be up

to 200 pixels.

NOTE: For a slower ﬁnd speed but better accuracy, enter higher Score and lower Sense values; for

a faster ﬁnd speed but less accuracy, enter lower Score and higher Sense values.

Circle Size Sets the size of the yellow and green circles on the Camera screen. A higher value results in a

larger circle.

Fast Match If this box is checked, the camera searches for mark more quickly but with less accuracy.

Detail

Sets the area within which the camera searches for a mark. If Search Detail is NOT checked, the

camera looks only within the speciﬁed range (set under Range). If Search Detail is checked, the

camera overrides the range settings and performs a full-screen search for the mark. This increases

the chances of ﬁnding the mark, but is slower.

Setting How the System Finds Marks (Optional)

Use the ﬁelds under CAMERA > SETUP > MATCH to adjust how the system functions when it searches for marks.

Setting How the System Captures Z Height Values (Optional)

By default, the system does not capture the Z-height value as you move the camera over the work

surface. This is a safeguard to prevent the dispensing tip from being damaged when a workpiece

surface is uneven.

Use the Set Z to Focus checkbox in the Expert window to set the system to automatically capture

Z-height values.

# Click Step Reference Image

• Click SYSTEM SETUP > OPEN.

CAUTION

When SET Z TO FOCUS is NOT

checked, the tip can collide with

obstacles on uneven workpieces,

causing damage.

• Select or deselect the SET Z TO

FOCUS checkbox.

When SET Z TO FOCUS is checked,

the system captures Z-height values.

• Click EXIT to close, then reopen the

DispenseMotion software for the

change to take effect.
