13. Set the operation mode. In either [AUTO] or [STEP], press the [MODE] command to access the following three modes of operation. • F1 : Product Carries out normal production of boards. • F2 : Simulate The XY-table and …

5. Transmit status data to the machine.

Status data is retained in the machine’s memory even after the machine’s power is

turned off. Thus, once status data has been transmitted to the machine, this step need

not be repeated. However, it is necessary to transmit status data to the machine after

performing the reset-start procedure. Status data can be modified either directly at

the machine, or indirectly using an host computer. When status data is modified

using the host computer, it must be transmitted to the machine before operation.

6. Transmit Proper data to the machine.

Proper data is retained in the machine’s memory even after the machine’s power is

turned off. Once Proper data has been transmitted to the machine, this step need not

be repeated. However, it is necessary to transmit Proper data to the machine after

performing the reset-start procedure. When Proper data is modified at the host

computer, the modified Proper data must then be transmitted to the machine before

operation. It is also possible to change a part of Proper data at the machine. If the

Proper data is transmitted to the host computer once the change is made at the

machine, then that Proper data will be saved at the host computer.

7. Transmit programs to the machine.

Programs are retained in the machine’s memory even after the machine’s power is

turned off. Once a program has been transmitted to the machine, this step need not

be repeated. However, it is necessary to transmit programs to the machine after

performing the reset-start procedure. New programs can be created using the host

computer. These must be transmitted to the machine before they can be used in

production.

8. EMERGENCY STOP button cancel

Release the EMERGENCY STOP button, then press the RESET button.

9. Select the production program.

Using either host computer or the machine [PROGRAM] command function, select

the production program.

10. Select the quantity of the production run.

Press the [PROGRAM], [QTY SET] command function keys and set the number of

boards to be produced. A setting of zero will make the machine run indefinitely.

Note: Scheduled production quantity can be set in the program. Enter the production quantity

into the Production_qty. field (in the Production_mode section at MCS), and transmit to

the machine. When the production run is complete the machine will stop and the

operator will be informed. (This function is used only in MCS systems. F4G systems

do not have this function.)

11. Zero-setting

The START button flashes and a “Machine Not Zero Set” message displays on-

screen. Press START to begin the zero-setting operation.

12. Commands

The F1 to F6 function keys can be used to execute commands.

Note: Some of these commands are disabled during vision processing (when a “Vision

System Booting...” message displays). In such cases, wait until vision processing is

completed before using those commands.

13. Set the operation mode.

In either [AUTO] or [STEP], press the [MODE] command to access the following

three modes of operation.

• F1 : Product

Carries out normal production of boards.

• F2 : Simulate

The XY-table and the device tables operate as they do during production, however

boards are not loaded.

• F3 : Idle

Machine carries out all functions except vision processing and fiducial mark reading.

The loader is inoperative at this time, and boards are not exchanged.

• F4 : Idle 2

In addition to the previous “Idle” function, IN/OUT carrier operation and board transfer

operation between the XY-table and the carriers are performed. Board exchanges do not

occur.

Caution: The operation mode “Product” is automatically selected when the power supply is turned

on. Operation modes “Simulate,” “Idle” and “Idle 2” are not for assembly.

1.2.2 Zero-Setting the Machine

This chapter describes the zero-setting procedure.

Servo motors control the position of each of the machine’s axes. The position of these

axes, however, are lost from the machine’s memory whenever the power is turned off.

Therefore, each time the power is turned on, all axes must be returned to their servo

origin (pulse 0) positions. The procedure used to do this is known as zero-setting.

The method of zero-setting an axis is described below, using the X-axis as an example.

1. If the X-axis deceleration-point sensor input is ON, the axis initially moves in the

negative (-X) direction until this input turns OFF.

2. The X-axis moves in the positive (+X) direction and decelerates when the

X-axis deceleration-point sensor turns ON.

3. After deceleration, the X-axis inches in the positive (+X) direction.

4. The X-axis stops moving when the encoder outputs the Z signal. (The Z signal is

output only once per motor revolution.) This X-axis position becomes the zero

position.
