(A02_07) Placement Level [mm]

Set the nozzle descent level for component placement, based on the

component placement surface.

Unit: mm

Data Input Range: −9.99 to +9.99

(a) The nozzle descent level for component placement is controlled ac-

cording to the parameter set in the "t" (component thickness) text box

of the label "Mold Size" in "Shape Data". However, it can be changed

deliberately by setting a parameter in this text box.

In normal cases, a value with "+" sign must be entered to avoid the

warpage (sagging) of a PCB.

(b) Enter a plus (+) value to set the nozzle descent level lower than the

component placement surface for component placement.

due to the control of the machine.

(A02_08) Focus Adjustment [mm]

Set the focus level when a component is recognized.

Unit: mm

Data Input Range: −99.99 to +99.99

(a) Actual operation range may be regulated (differ from the set values)

due to the control of the machine.

(b) In normal cases, the height level for component recognition is deter-

mined according to the parameter set in the "t" data box of the label

"Mold size". However, when a spot regarded as a target to be recog-

nized deviates from the focus point due to the shape of a component,

the set parameter can be used to correct the deviation.

in the figure, enter the dimension (A) with "+" sign in the data box.

When a value with "+" sign is entered, the head will descend further

(as much as the set value) than the normal stroke and the photo-

image of the component is taken for component recognition. When

the parameter set in the "t" data box of the label "Mold size" can be

used as the level for component recognition, "0" (zero) must be set in

this data box.

(A02_09) Error Process 1

When no component can be picked up (Missing components), the

machine stops in an error condition according to the number of errors.

Set a parameter in this data box to designate the number of continu-

ous component missing errors to be counted in order to stop the ma-

chine in an error condition.

Data Input Range: 1 to 9

1 : The machine stops in an error condition after no component (rec-

ognition error) is detected once.

2 : The machine stops in an error condition after no component (rec-

ognition error) is detected continuously twice on the same feeder.

n : The machine stops in an error condition after no component (rec-

ognition error) is detected continuously "n" times on the same

feeder.

(a) Recommended Data

Components packaged in 8 mm Tape : 2

Components packaged in 12 mm or Wider Tape : 1

Components packaged in Tray or Stick Feeder : 1

Pick-up error on the tape of width 12 mm or more in the component

(tray or vibration stick component) might cause malfunction. There-

fore, we recommend stopping the machine when the error is first de-

tected.

(b) When the alternate function is activated, the set parameter becomes

one of the requirements for alternate operation start.
