1.4 Adjusting the W-axis initial position
The W-axis initial position is the distance expressed as a minus value
between the conveyor rails when the W-axis is in the return-to-origin
position. To set the W-axis initial position, follow these steps.
1 Perform return-to-origin.
e
2 Press the emergency stop button and determine the initial
position.
Measure the conveyor width W (distance between the fixed rail and the
movable rail). Subtract 0.5mm from the width W as a clearance margin,
and then prefix a “minus” sign to this value. This value is the W-axis initial
position.

3 Open the software limit screen and enter the initial
position.
1. Select <3/3/B1 ADJUST TARGET> − ”Soft. Limit” and press the [ENTER]
key.
2. Use the arrow keys to line up the cursor with “Init.Pos” of the conveyor
whose width you measured in Step 2 (for example, W1).
3. Use the number keys to enter the initial position value obtained in Step
2.

1.5 Y-axis (A/B table) initial position
For smooth PCB transfer, the carry-in conveyor, A/B tables and carry-out
conveyor must be aligned straight. To ensure this, the initial position of the
Y-axis (A/B tables) is specified on the Soft Limit screen. If resetting
becomes necessary, use the following procedure.
1 Perform return-to-origin.
e
2 Press the emergency stop button.
3 Align the conveyor rails.
Move the A and B tables by hand to align them with the carry-in and
carry-out conveyors, so that the fixed conveyor rails are all lined up
straight.

4 Open the software limit screen.
Select <3/3/B1 ADJUST TARGET> - ”Soft. Limit” and press the [ENTER]
key.
5 Enter the Y-axis initial positions.
1. Use the arrow keys to line up the cursor with “Init.Pos” in the “Y1/A-
TBL” row.
2. Press the [F10] key and set the teaching conditions.
Select any teaching unit and speed in this case.
3. Press the [F10] key twice to enter the Y1-axis initial position.
4. Next, move the cursor to “Init.Pos” in the “Y1/B-TBL” row and press the
[F10] key twice to enter the Y2-axis initial position.
