Appendix A, Command Function Reference

(continued)

Stop Point

Click Function

Registers a Stop Point at the current XYZ location. When this command occurs, the dispensing tip moves to the

registered location and waits until the START or CONTINUE button is pressed.

Trig Mark

Click Function

Double-click

address and

select from

drop-down

This command is not used on GV Series systems.

Var

Click Function

Double-click

address and

select from drop-

down menu

Allows a numeric value to be assigned to a symbol or character; once assigned, the symbol or character

can be used in a program in place of the numeric value. A set command can also be used to cause the

system to increase or decrease a coordinate by the assigned numeric value. Var can be used with the Find

Mark and Fiducial Mark commands.

Parameter Description

Symbol Enter the symbol or character that will represent the assigned Value

Value Enter the numeric value that the symbol or character represents

Wait Point

Click Function

Registers a Wait Point to occur immediately after the previous command. When this command occurs, the

dispensing tip waits at the end point of the previous command for the speciﬁed Wait Time (in seconds).

Z Clearance Setup

Click Function

Speciﬁes the height to which the dispensing tip raises after each dispense command. The purpose of Z

Clearance is to raise the tip high enough so that it clears all obstacles as it moves from one point to another.

If there are no obstacles between any of the points, a small Z Clearance value, such as 5mm, can be used to

minimize the program cycle time.

Z Clearance is further deﬁned as an absolute value (0) or a relative value (1) . When speciﬁed as a relative value,

it is the distance the tip raises relative to the taught point location. When it is speciﬁed as an absolute value, it is

the distance from the Z axis zero position to which the tip raises regardless of the Z-axis value of the taught point

location.

Nordson EFD recommends inserting a Z Clearance command at the beginning of a program.

Parameter Description (see illustrations below)

Value The distance (in mm) the tip raises after dispensing.

0(Abs), 1(Rel) How the tip raises: 0(Abs) = absolute, 1(Rel) = relative.

Z Clearance = 10 mm relative Z Clearance = 10 mm absolute

AppendixB, Non-Wizard Setup Procedures

All setup and calibration procedures are guided by the Robot Initial Setup wizard, which should be used after any

system change, including tip change-out. However, the procedures in this appendix can be performed individually

and are provided here for your reference as needed.

Setting the Camera Scale

Click Step Reference Image

• Click the CAMERA tab.

• Jog the camera to a point of reference that

is located on the lower right corner of the

workpiece.

• Bring the image into focus. Refer to

“Camera” on page18 as needed for

instructions on focusing the camera.

• Click the CAMERA tab and then click

SCALE.

The Scale window opens.

NOTE: When the camera views an object, it

converts the pixels to a true measurement.

For the camera to make this conversion

accurately, you must “teach” the camera

what the size of an object is in comparison

to pixels per inch by setting the camera

scale.

• Choose a point of reference on the

workpiece and jog the camera so that the

reference point is located in the lower right

quadrant of the camera screen, then click

the point.

• Jog the camera again until the same

reference point is located in the upper left

quadrant of the camera screen, then click

the point.

The camera scale is now set.
