Possible Solutions

The drive is operating the motor (the drive is in Drive Mode).

Stop the drive and change to Programming Mode.

Parameter A1-01 = 0 [Access Level Selection = Operation Only].

Set A1-01 = 2 [Access Level Selection = Advanced Level] or A1-01 = 3 [Expert Level].

Parameter H1-xx = 1B [MFDI Function Select = Programming Lockout].

Activate the terminals to which H1-xx = 1B is set, and then change the parameters.

You entered an incorrect password in A1-04 [Password].

  • Enter the correct password to A1-04 again.

  • If you forgot the password, set the password again with A1-04 and A1-05 [Password Setting].

    Note:

    If you set the password, you cannot change these parameters until the password aligns:

    • 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 User Parameter 32]

The drive detected Uv [Undervoltage].

  • View U1-07 [DC Bus Voltage] to see the power supply voltage.

  • Examine the main circuit wiring.
