Auto-Tuning uses motor characteristics to automatically set drive parameters.

Refer to the motor nameplate or the motor test report for the necessary information for Auto-Tuning.

Figure 1. Motor Nameplate (Example)

This procedure shows how to do Rotational Auto-Tuning.

  1. Push [F2 Key] (Home) to show the HOME screen.
    Note:

    • When the drive is in HOME Mode, the screen shows [Home] in the upper right-hand corner of the screen.

    • If the screen does not show [Home] for [F2 Key], push [F1 Key] (Back), and then push [F2 Key] to show [Home].

  2. Push [F2 Key] (Menu).
  3. Push [Up arrow key] or [Down arrow key] to select [Auto-Tuning], then push [ENTER Key].
  4. Push [ENTER Key].
  5. Push [Up arrow key] or [Down arrow key] to select [Rotational Auto-Tuning], then push [ENTER Key].
  6. Follow the messages shown on the keypad to input the necessary Auto-Tuning data.

    Example: Push [LEFT Key] or [RIGHT Key] to select the specified digit, then push [Up arrow key] or [Down arrow key] to change the number. Push [ENTER Key] to save the change and move to the next entry field.

  7. Follow the messages shown on the keypad to do the next steps.
  8. When the keypad shows the Auto-Tuning start screen, push [RUN key].

    Auto-Tuning starts.

    When doing Rotational Auto-Tuning, the motor will stay stopped for approximately one minute with power energized and then the motor will start to rotate.

  9. When the keypad shows this screen after Auto-Tuning is complete for 1 or 2 minutes, push [ENTER Key] or [RIGHT Key].

    The keypad will show a list of the changed parameters as the result of Auto-Tuning.

  10. Push [Up arrow key] or [Down arrow key] in the parameter change confirmation screen to check the changed parameters, then select [Auto-Tuning Successful] at the bottom of the screen and push [ENTER Key].

    To change a parameter again, push [Up arrow key] or [Down arrow key] to select the parameter to change, then push [ENTER Key] to show the parameter setting screen.

Auto-Tuning is complete.

Note:

If the drive detects an error or you push [STOP key] before Auto-Tuning is complete, Auto-Tuning will stop and the keypad will show an error code. Endx identifies that Auto-Tuning was successful with calculation errors. Find and repair the cause of the error and do Auto-Tuning again, or set the motor parameters manually. You can use the drive in the application if you cannot find the cause of the Endx error. Er-xx identifies that Auto-Tuning was not successful. Find and repair the cause of the error and do Auto-Tuning again.
