4.2.3 Nozzle/Parts Statistical Information

The “statistical information” operation setting described above permits the display of

nozzle/parts error status data which can be checked during automatic operation.

To view this data during automatic operation, select [Noz/parts stats] at the [Automatic]

screen.

[Data display list]

Error rates display for the 5 nozzles and slots with the highest error rates. (Error rates for

other nozzles and slots can be viewed by using the scroll bar to scroll down.)

The list shows the No., the error rate, the error count, and the total number of pickups.

[Manually reset statistical data]

Press to reset (clear) the statistical data for the selected nozzles/slots.

This button is disabled during automatic operation.

Nozzle & Slot Display [Machine Info Screen]

Error rates display when the nozzle and slot display is clicked at the [Machine info]

screen. If a parts-out slot is clicked, information displays for the slot which was clicked

at the “Parts-out info” list.

Nozzles and slots display in yellow when the statistical information indicates a

caution condition.

Statistical Processing

Data collection processing

When a pickup and placement cycle (hereafter referred to as 1 cycle) is completed, the

number of errors (non-placement count) and the number of pickups are processed by the

statistical processing counter. The counter collects data from the last 10,000 cycles for

each nozzle and slot.

The status is refreshed following the count operation. (Refresh processing also occurs

when returning to the automatic operation screen after making an operation conditions

change at the [Operation Settings] screen when operation is not in progress.)

Mode

Error stop

Auto recovery

The number of errors (non-placement count) and pickups are counted after

each cycle.

Prior to count processing which is performed after 1 cycle, operation varies,

depending on whether or not a recover operation is to occur.

When recovery is executed:

During the recovery operation, the number of pickup errors is counted and

saved for each nozzle and feeder by the dedicated counter.

When recovery is not executed:

• [Parts-out] ⇒ Dedicated recovery counter is reset.

• [Other error] ⇒ The dedicated counter data (error count, pickup count)

is saved at the statistical processing counter.

If placement has occurred:

The number of pickups is counted.

The dedicated counter data (error count, pickup count) is saved at the

statistical processing counter.

Data Reset Conditions

Auto reset: Reset occurs automatically during automatic operation preparation after

switching production programs or editing data. Nozzle and slot data

where changes occurred are initialized at that time. (Changed data are

initialized when the automatic operation screen is opened.)

Manual reset: Reset is possible by pressing the [Data Clear] button at the [Statistical

info] screen.

Caution Processing

1. The signal tower lights.

2. Relevant nozzles and slots display in yellow at the [M/C stat info] screen.

3. Relevant data displays in red at the [Statistical info] screen.

Count processing does not occur, however, when the following conditions apply:

• When in the Idle mode.

• When in the Pass mode.

• When in the Error Pass mode.

Cycle Stop Processing

At caution processing operations, the following occurs in addition to items 1~3 above.

(The same applies under “no-check” conditions.) The following message displays at the

status bar, and a cycle stop occurs: “Please correct the cycle stop cause detected by

statistical processing.”

Signal Tower Processing

• When a warning condition occurs, the signal tower lights in accordance with its

settings.

• The warning status remains in effect until a reset occurs.

• If the warning status is cleared, the signal tower lamp remains on if other

statistical warning causes remain uncorrected.
