    Why Kinco Inverter Drive settings of parameters cannot be changed?
    • K
      Katie AndersonAug 10, 2025
      The inability to change parameters on your Kinco Inverter Drive could stem from several reasons: * Parameters are not allowed to be changed during operation: Change the parameters at STOP status. * b4.02 is set to 1 or 2: Set b4.02 to 0. * A user password is required: Input the correct user’s password. * Parameters are actually detected, not allowed changing: Do not try to change these parameters, users are not allowed to change these.
