BACKUP PLATE UP/DOWN

This is the offset data for the origin position of the backup

plate up/down axis which ascends or descends during P.C.B.

positioning.

A plus (+) value decreases the ascending stroke during P.C.B.

positioning.

CONVEYOR WIDTH

This is the offset data to adjust the absolute value for the con-

veyor width. Enter the difference between the actually mea-

sured width and the data width caused when the conveyor width

is set up to the width specified by a parameter.

When the actually measured width is narrower than the width

specified by a parameter, a plus value must be entered.

TEACHING PLATE X, Y

The set offset parameters are used to adjust the positional de-

viations based on the design dimensions of the teaching plate

(the glass jig used for automatic teaching operation of various

offset data) stock position. The values based on the PL-XY

coordinate system must be entered in the data boxes.

Note: The teaching plate section differs according to the ref-

erence position of the machine.

Ref.: The manual alignment teaching operation is possible.

When offset parameters are entered with “+” (plus) signs for

“X (mm)” and “Y (mm)”, the X/Y head moves in the (+) di-

rection in the PL-XY coordinate system.

TEACHING PLATE L

The set offset parameter is used to adjust the vertical (height

direction) deviation based on the design dimension of the teach-

ing plate (the glass jig used for automatic teaching operation

of various offset data) stock position.

When the teaching plate is installed lower than the design value,

a plus value must be entered.

Ref.: When the “X”, the “Y”, or the “L” data box of the

label “TEACHING PLATE” is selected, the [TEACH-

ING] key appears at *1.

When this key is pressed, the “UNIT MANUAL ALIGN-

MENT TEACH” display appears on the screen.

FEEDER (A) OFFSET X (mm) and Y (mm)

The feeder (A) offset data is used to adjust the positional de-

viation based on the design dimensions representing the com-

ponent pick-up position for each individual feeder slot Nos.

(FDR. NO.).

The values based on the PL-XY coordinate system must be

entered in the data boxes.

These parameters must be measured, using the master jig and

set as the data for positional alignment with each feeder’s com-

ponent pick-up position.

Ref.: The manual alignment teaching operation is possible.

• The feeder (A) offset data is used independently for the machine and repre-

sents the feeder’s component pick-up position indicated by each individual

feeder slot Nos. (FDR. NO.).

• The feeder (B) offset data is used to correct the variation in each feeder to be

installed.

When the [FEEDER (A) OFFSET] key is pressed at the “OFFSET DATA”

display, the following display appears on the screen.

When offset parameters are set with a plus (+) sign, the com-

ponent pick-up directions (position) are changed to “X (+)”

and “Y (+)” shown in the above figure.

Note: Both rear (Slot Nos. 101 to 139) and front (Slot Nos.

201 to 239) feeders are not based on the feeders them-

selves. They are based on the coordinate system of the

machine.

Ref.: When the [TEACHING] key *1 is pressed, the “UNIT

MANUAL ALIGNMENT TEACH” display appears

on the screen.

Refer to “6.8.2 Feeder (A) Offset of Section 3 in Volume

4” for details.

FEEDER (A) OFFSET L (mm)

The set parameters are used to adjust the deviation of the

feeder’s component pick-up height based on the design dimen-

sions for each individual feeder slot Nos. (FDR. NO.).

These parameters are reflected on the descending stroke of the

head required to pick up a component.

Fig. 5.12

When a value is entered with a plus (+) sign, the pick-up height

is changed to “L (+)” shown in the figure above, concluding

that the descending stroke has increased.
