4. Adjustments (Preparation for the mounting adjustment)

After installing the machine and performing safety check, turn on the power and the air supply in

order to start up the machine.

This section describes the works and adjustments need to be done before performing mounting

adjustment (by ACP) after starting up the machine.

4.1. System data backup

Note:

The system data is basically backed up at the factory when the adjustment is performed after

assembling the machine. However, in case some changes of the settings are made before

shipment of the machine (ex. When you perform checking with the customer if the machine meets

the specifications.), the changes may not be saved. Please make a backup copy of the system

data before adjustment.

(* Please refer to the Operation manual for how to backup the data.)

4.2. Dual drive offset adjustmet for the Y-axis

Y-axes are driven by two motors. The “Return-to-origin” motion is performed with the Y1 axis, and

the pulse indicates the position of the Y2 axis when the Y1 is at the original position.

The Y2-axis moves in synchronization with the Y1 axis, and the deviation of the motion between

the two axes is monitored by pulse. The deviation due to the relocation of the machine can be

corrected by performing “Y-axis dual drive adjustment” in order to increase the accuracy of the

monitoring.

1. Click on the [Axis] button on the CalibSm main menu to display “Axis” screen, then select

“Dual drive offset” from the “Adjust Item”.

 After selecting “Dual Drive Offset”, fill in the current value of the “Dual Offset” on the check

sheet.

2. Click on the [Originize] button to check the measured value.

3. Check the dual drive offset value and save the data.

Make sure that the offset value of the Y2 axis (Pulse) falls within the specification, then save

the data.

 Fill in the current value (Current) and the measured value (Result) on the check sheet.

<Specification>: 63000 - 65000

Note:

Even though the value falls within specification, if the value (pulse) after adjustment is more than

1000 (pulse) larger or smaller compare to the value before adjustment, please renew the data.

If the variation is within 1000 (pulse), the adjustment does not need to be performed.

Figure 5

Caution:

- If the result does not fall within specification, please investigate the possible cause of the

problem. (Abnormal level of the base, deviation of the coupling, abnormal motor, and so on)

- When replacing the coupling or the motor, please adjust the pulse to 64000 +- 300.
