A1-05 Password Setting
(0105)
This parameter locks these parameters:
• A1-01 [Access Level Selection]
• A1-03 [Initialize Parameters]
• A1-06 [Application Preset]
• 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
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 [2-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.

Check the I/O signals and the external sequences for the drive before you set the Application
Preset function.
When you set the Application Preset function (A1-06 ≠ 0), it changes the I/O terminal functions for the drive and it
can cause equipment to operate unusually. This can cause serious injury or death.
