2. Changing the Position of the Back-up Pins

Point

Change the position of the back-up pins (vacuum or solid) to support a panel during

production. For panels where upward warping is a problem, vacuum back-up pins

should be used to maintain the flatness of the mounting surface.

Procedure

1. Lower the panel lifter if it is raised.

2. Adjust the conveyor width to the maximum width.

3. Remove the MFU from the machine.

4. Pull the back-up plate sideways slightly, then lift it up to remove it.

Precautions when mounting/demounting the back-up plate:

• Use care to avoid interference between the plate and the sensor. Such interference

could break the sensor.

• Because the procedure is performed from the MFU side, use care to avoid

interference with the camera.

5. Detach the back-up pins by loosening their fastening bolt, and reposition them as

necessary.

6. When the back-up pins are in place, slide the back-up plate back onto the lifter. Be

sure to push it into the back-up plate until it contacts the block (refer to the

diagram above).

7. Before raising the lifter, make sure that the back-up pins do not interfere with the

adjustable side of the conveyor. If there is interference, reposition the back-up

pins.

3. Using the Maintenance Key

Point

Maintenance and adjustment sometimes require operation of the servo motors with the

safety doors open. Special maintenance commands and a maintenance key are used in

such cases, allowing the servo system power to remain on while the safety doors are

open.

Features of the Special Maintenance Commands

• The servo system power supply is maintained for operation with the safety doors

open.

• The servo system power supply is maintained without having to clamp the MFUs.

• The maximum speed of the servo motors has been reduced during use of the

Special Maintenance commands.

• The servo motors stop immediately when the inching keys at the [JOG] screen are

released.

• The main operable parts are the servo motors, conveyor motors, the strobe lighting

and each I/O.

Procedure

1. From the [Main] screen of the control panel, select [Maintenance C] [Custom

Maintenance] to open the [JOG] screen.

2. When the message "Turn the Maintenance Switch ON." displays, press the

EMERGENCY STOP button and open the safety door.

3. Insert the maintenance key into the maintenance switch inside the machine, and

switch the key to ON.
