(4) Press the pertinent “FDR.” key or the [ALL CLEAR] key E to select the
objective parameters.
In the case of tray feeders (option), press each “BLK.” key.
• Select the feeder base where the data to be cleared belong by pressing
the [BASE #1], the [BASE #2], the [BASE #3], or the [BASE #4] key
D.
Ref.: The desired feeder base can be selected in the selection B at
the “FEEDER (B) OFFSET” display.
• Press the [ALL CLEAR] key to clear all the data.
When the [ALL CLEAR] key is pressed, it turns red and the “FDR.”
keys G turn blue.
• To clear each data individually, select the pertinent “FDR.” key G. The
selected “FDR.” key turns blue.
• To cancel the all data clear mode, press the [ALL CLEAR] key again
before the [CLEAR] key.
(The [ALL CLEAR] key in red turns normal.)
(5) Press the [CLEAR] key F. The offset data of the selected feeder is cleared
to “0” (zero).
Ref.: When the [TEACHING] key C is pressed, another “FEEDER (B) OFF-
SET” display appears on the screen for teaching operations.
Note: Never modify the parameters set at the “FEEDER (A) OFFSET” dis-
play described in “3. FEEDER (A) OFFSET and FEEDER (B) OFF-
SET Displays of Section 5 in Volume 2”.
This data is used independently for the machine. If the data is modified
carelessly, components may not be picked up from the feeders.

5.3 Pattern Program Checking for Production Model
5.3.1 Setting and Checking of P.C.B. Recognition
P.E.C. Recognition Function
The P.E.C. camera checks the coordinates of fiducial marks (2 or 3 places) on
the P.C.B. and determines the deviation from theoretical coordinates.
Furthermore, this function is used in the actual production, the positional de-
viations of the placed components are automatically corrected.
Refer to “2.3.2 Operation Data (P.E.C. Recognition) of Section 2 in Volume 2”
for details.
When “ON” is set in the “P.E.C. RECOGNITION” data box at the “OPERA-
TION DATA” display, follow the procedure below to prepare for automatic
operation.
Operation Procedure
(1) Turn on the “P.E.C. RECOG LIGHT” switch on the console panel and
then turn off the “LIGHT” switch.
(2) Prepare a P.C.B. to be used for actual production and make a P.E.C. rec-
ognition test to verify each set parameters.
Refer to “7.1 P.E.C. RECOG TEST Display of Section 3 in Volume 4” for
details on the P.E.C. recognition test.
(2.1) Whenever the parameters set in the “MARK TYPE”, “MARK
SIZE”, “WINDOW SIZE”, “RECOGNITION ALGORITHM”,
“MARK IMAGE”, and “MARK LEVEL” data boxes are
changed, be sure to modify the original pattern program data.
Refer to “4. PATTERN PROGRAM Display of Section 2 in
Volume 2” for details on how to modify the pattern program data.
(2.2) Determine the gain and level data of Camera #3 (for P.E.C.
recognition). The determined gain and level must be entered in
the offset data.
Refer to “10. P.E.C. RECOG CAMERA OFFSET Display of
Section 5 in Volume 2” for details on the offset data.
5.3.2 Confirmation of Placement Position
Perform an X/Y beam test to verify that the component placement position is
correct.
Refer to “7.3 X/Y BEAM TEST Display of Section 3 in Volume 4” for details.

5. Preparation and Confirmation before Operation
5.3.3 Confirmation of Components
(1) Verification of Component Library Data
A component recognition test must be performed to verify that the cre-
ated component library data is normal.
Refer to “7.2 COMPONENT RECOG. TEST Display of Section 3 in
Volume 4” for details.
(2) Confirmation of Pick-Up Position
If the component pick-up position deviates greatly from the center of the
nozzle, it will cause a pick-up error. To avoid such an error, the compo-
nent pick-up position must be taught in the following cases.
• When the center of the picked component deviates from the center of
the nozzle, perform the teaching operation (teaching operation for pick-
up position) on the feeder (B) offset data.
• When the component has a limited surface to be picked up or cannot
be picked up because it has a hole or a protrusion at its center, use the
[TEACH ECC. PICKUP POS [PICKUP LOC. ADJ] key to perform
the teaching operation on the eccentric pick-up position.
CAUTION
Only an well-trained personnel shall perform
teaching operations.
Otherwise, the pick-up rate may deteriorate be-
cause teaching operations are performed to ad-
ditionally modify the component library data and
the pattern program data.
Refer to “6.9 PICK-UP LOCATION Display of Section 3 in Volume 4”
for details.
5.3.4 Placement Verification
Place actual components on a P.C.B. and verify that the component can be
placed without any hindrance.
Refer to “6. Starting, Emergency Stop, and Temporary Stop (Pause) Opera-
tions for Automatic Operation (“PLACE” Mode) of Section 2” for the proce-
dures.
5.4 Setting of Operation Mode
Follow Steps (1) through (4) below before starting the automatic operation
(“PLACE” Mode).
(1) Automatic Feeder Axis Adjustment Mode
Refer to “5.1 AUTOMATIC FEEDER AXIS ADJUSTMENT MODE
Display of Section 3” for details.
(2) Overall Tact-Time Reduction
Refer to “5.2 OVERALL TACT-TIME REDUCTION Display of Sec-
tion 3” for details.
(3) Recognition Monitor Display Mode
Refer to “5.3 RECOG MONITOR DISPLAY MODE Display of Section
3 ” for details.
(4) P.E.C. Manual Alignment Mode
Refer to “5.4 P.E.C. MANUAL ALIGNMENT MODE Display of Sec-
tion 3” for details.
