Step & Repeat Y

Click Function

Works exactly like Step & Repeat X except that priority is given to the Y axis instead of to the X axis, as shown

below.

Step & Repeat, X Axis Direction Step & Repeat, Y Axis Direction

Step & Repeat Z

Click Function

Double-click

drop-down

Enables the repeat of the dispensing pattern onto many identical workpieces that are mounted on a ﬁxture plate

and aligned in rows and columns.

Parameter Description

Z Offset

The distance (inmm) between each workpiece tier in the Z direction.

• A positive Z Offset value moves the tip away from the work surface.

• A negative Z Offset value moves the tip towards the work surface.

Range: 0.1–100 (mm)

Tier

The number of tiers (or levels) in the Z direction.

Range: 1–9999

Label The address where the Step & Repeat Z command begins.

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
