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]

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.

• 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.

A1-06: Application Preset
WARNING! Sudden Movement Hazard. 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.
