Goto Label

Click Function

Causes the program to jump to the address in the program that has the speciﬁed label.

Height Sensor

Click Function

Double-click

address and

select from

drop-down

Measures the height of an object on a workpiece where a dispense dot is to be placed; the measured data is

then used to adjust dispensing accordingly for any height changes between workpieces.

NOTE: For this functionality, the optional height sensor must be installed and set up. Refer to”AppendixF,

Height Sensor Setup and Use” on page142 for all information related to the height sensor.

Initialize

Click Function

Causes the robot to perform an initialization. The dispensing tip moves to the home position (0, 0, 0) and the

robot relocates the home position using the home position sensors.

Input

Click Function

Causes the program to check for an input signal at the speciﬁed port and to turn the input ON or OFF.

Parameter Description

Port(1~8) Sets the input port number.

0 Off, 1 On Turns the input OFF or ON.

Address or

Label

Causes the program to check the input at the speciﬁed address or label. Click Change to toggle

between Address and Label.

Input Ready

Click Function

Double-click

address and

select from drop-

down menu

Used to communicate with external devices: If Input Ready is ON, the system checks the assigned port and

acts accordingly; if Input Ready is OFF, the system does not check the assigned port and moves on to the

next command.

Parameter Description

Port(1~8) Sets the input port number for the system to check.

0 Off, 1 On Turns Input Ready OFF or ON.

Jet Step

Click Function

Double-click

address and

select from

drop-down

Used in tandem with a Line Start and a Line End command to cause the system to dispense a stitched series

of dots between the commands at the speciﬁed length (Jet Step) and for the speciﬁed amount of time (Pulse

Width). This command is useful for jetting applications in which extremely quick dispensing is required.

NOTE: For PICO jet dispensing, this command can be used with Line Start and Line End commands to create a

stitched pattern. An example program and resulting pattern are shown below.

Parameter Description

Jet Step The distance (inmm) between the stitched dots.

Pulse Width How long the dispenser stays open (in ms) for each deposited dot.

Adjust Offset value (in mm) that the system applies to each coordinate value in the program. This

setting can be used to compensate when a dispensing program is slightly off from the desired

pattern.

Example of a stitching program using the Jet Step command for a PICO jet valve

Label

Click Function

Registers a numeric label that can be used as a reference in the Goto Address, Goto Label, Loop Address, Step

& RepeatX, Step & Repeat Y, and Call Subroutine commands. Using a Label is a good alternative to using an

address number because a Label does not change when commands are inserted or removed. A maximum of 64

labels is allowed per program; each label can have up to 8 numbers.

Light

Click Function

Double-click

address and

select from

drop-down

Sets the luminance of the light source at a speciﬁed point in the program between 0 (no luminance) and 255

(brightest).

NOTE: This command is present only if an optional light accessory is installed.

Line Dispense Setup

Click Function

Sets how the system dispenses a line of ﬂuid. When dispensing high-viscosity ﬂuids, there is often a delay

between when the dispenser opens and when ﬂuid begins to ﬂow. Use the Line Dispense Setup parameters to

compensate for this delay.

Parameter Description

Pre-move

Delay

The time the dispenser stays open at the start of a line before moving. This delay time prevents

the tip from moving along the line until ﬂuid is ﬂowing.

Settling

Distance

The distance the robot moves from the beginning of a Line Start before the dispenser turns on.

This distance allows the robot sufﬁcient time to build speed and is used primarily to eliminate the

deposit of too much ﬂuid at the beginning of a line.

Dwell Time Delay time that occurs at the end of a line after the dispenser closes to allow the pressure to

equalize before the tip moves to the next point.

Node Time Delay time that occurs only for a Line Passing command. The dispensing tip passes through

the Line Passing point and waits at the Line Passing point, with the dispenser activated, for the

speciﬁed time period.

Shutoff

Distance

The distance before the end of a line when the dispenser closes to prevent excess ﬂuid from

being deposited at the end of the line, as shown in the illustration below.

Shutoff

Delay

The time the dispenser stays open after it stops at the end of a line.

Shutoff Distance

Tip continues moving to the end of the lineDispenser turns off here

Illustration of the Shutoff Distance parameter

Line End

Click Function

Registers the current XYZ location as a Line End point.

NOTE: The correct sequence of commands for a line is as follows: (1) Line Start, (2) Line Passing, (3) Line End.

Line Passing

Click Function

Registers the current XYZ location as a Line Passing point. This is a location on a line where the dispensing tip

changes direction, such as at the corner of a rectangle.

NOTES:

• The correct sequence of commands for a line is as follows: (1) Line Start, (2) Line Passing, (3) Line End.

• Also use a Line Passing point before and after an Arc Point command.
