0000

(0000 - 9999)

This parameter can lock these parameter settings:

  • A1-01 [Access Level Selection]

  • A1-02 [Control Method Selection]

  • A1-03 [Initialize Parameters]

  • A1-06 [Application Preset]

  • A1-07 [DriveWorksEZ Function Selection]

  • A2-01 to A2-32 [User Parameter 1 to 32]

Note:

  • Usually, the keypad will not show A1-05. To show and set A1-05, show A1-04 [Password] and then push [STOP Key] and [Down Arrow Key] on the keypad at the same time.

  • After you set A1-05, the keypad will not show it again until you enter the correct password in A1-04. Make sure that you remember the A1-05 setting value. If you do not know the A1-05 setting value, contact Yaskawa or your nearest sales representative.

  • When A1-03 = 2220, 3330 [2-Wire Initialization, 3-Wire Initialization], the drive is initialized to A1-05 = 0000. Be sure to set the password again when a password is necessary for the application.

  • Change the setting value in A1-05 to change the password. The new setting value becomes the new password.

  • When you use the password to unlock and change a parameter, enter a value other than the password in A1-04 to lock the parameter again with the same password.

  • If A1-04 ≠ A1-05, MEMOBUS Communication cannot read or write A1-05.
