You know, when you purchase a drive, it has pre-loaded parameters which are called factory settings, which manufacturer loads in allen bradley variable frequency drive (vfd). That is also mentioned in the manual of allen bradley variable frequency drive (vfd) alright that is called factory setting.

P101 – motor np voltage
Stop drive before changing this parameter.
Set to the motor nameplate rated voltage.

P102 – motor np hertz.
Stop drive before changing this parameter.
Set to the motor nameplate rated frequency.

P103 – motor ol current.
Set to the maximum allowable motor current.
