Calibrating a Tool Through the STa6000 or STpad

Connecting the STa6000/STpad

The STa6000/STpad can be connected to the controller in two ways:

  • Connecting the STa6000

Connection

Remarks

COM port

Connect the Atlas Copco USB to Serial adapter to the controller's USB port using the ACTA Serial cable. Connect the STa6000 to the Serial Adapter using a USB cable.

Ethernet port

Connect the ethernet cable between the STa6000 and the controller's Factory Ethernet port, or the factory network.

  • Connecting the STpad

Connection

Remarks

COM port

Connect the STpad to the Controller's COM port using the ACTA Serial cable.

Ethernet port

Connect the ethernet cable between the STa6000 and the controller's Factory Ethernet port, or the factory network.

Performing the QA Calibration through the STa6000 or STpad

  1. Make sure the tool is connected and assigned to a virtual station on the controller.

    Single tightening programs cannot be used for calibration purposes. Make sure a batch program is selected.

  2. On the home view, go to the Tool tab and select QA Calibration on the left pane. Then, set QA Calibration to On.

  3. Select the virtual station the tool to be calibrated is connected to, and select the connection type to be used (TCP of COM port).

    Note that the default port for communication is 4561

  4. Connect the STa6000/STpad to the controller, and select the correct virtual station.

  5. Start the calibration from the STa6000/STpad.

    The STa6000/STpad requests controller information, including tool information and tightening program.

  6. Execute the tightening. When the calibration device detects a tightening, it requests the tightening result from the controller.

  7. Repeat the above step until all tightenings in the batch have been executed.

    Once completed, the STa6000/STpad creates a report, as well as calculate a new calibration value for the tool.

  8. Select Store in the STa6000/STpad to send the new calibration value to the controller, which in turn writes it to the tool.

During calibration, if the tightening program is changed, or the sequence/batch is updated, the calibration is terminated.

There is no limit in the batch size used for calibration purposes. However, the STa6000 can only display two digits as batch size. Thus, the counter on the Sta6000 reads 00 for 100.

After calibration is completed, perform a tightening to verify that the new values are correct.
