Fill End

Click Function

Double-click

address and

select from drop-

down menu

Used in tandem with Fill Area and Fill Start, the Fill End command designates the end of a Fill Area

command. The correct sequence of commands for a ﬁll area is: (1) Fill Start, (2) Fill Area, (3) Fill End.

NOTE: Line End can be used in place of Fill End.

Fill Start

Click Function

Double-click

address and

select from drop-

down menu

Used in tandem with Fill Area and Fill End, the Fill Start command designates the start of a Fill Area

command. The correct sequence of commands for a ﬁll area is: (1) Fill Start, (2) Fill Area, (3) Fill End.

NOTE: Line Start can be used in place of Fill Start.

Find Angle Mark

Click Function

Double-click

address and

select from

drop-down

Used in tandem with Fiducial Marks to cause the system to search for a change in the XY orientation of a

workpiece by searching in an angle-shaped area on the workpiece. If a change is found, the system adjusts the

dispense program accordingly.

EXAMPLE: If Start Angle = 0 and End Angle = 90, the system searches for marks within the speciﬁed angle-

shaped area. If a workpiece differs from the previous workpiece within that area, the system adjusts the dispense

program accordingly. If the system cannot ﬁnd the marks within the speciﬁed angle-shaped area, it skips the

workpiece.

Parameter Description

Start Angle The angle (in degrees) at which the systems starts searching.

End Angle The angle (in degrees) at which the system stops searching.

Find Mark

Click Function

Causes the system to search for the mark speciﬁed in the No. (number) ﬁeld of a Find Mark command. The

mark is then used by the Mark Adjust command to adjust the dispense program accordingly for any XY position

changes between workpieces.

NOTES:

• Only one Find Mark is required in a program for the system to perform this function correctly.

• A Find Mark is different from a Fiducial Mark. A Find Mark is used only to check the XY position of a workpiece

whereas a Fiducial Mark is used to check the orientation of a workpiece.

• Refer to “About Marks” on page28 for more information on marks.

Goto Address

Click Function

Causes the program to jump to the speciﬁed address.

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.
