Data format [19] Amperage value Decimal data (positive ):

Min. unit 0.01 inverter capacity is not more than 30HP/CT, 40HP/VT.

Min unit 0.01 for not less than 40HP/CT, 50HP/CT.

Example: F11 (electronics thermal overload relay 1 level) 107.0A (40HP) 107.0 X 10=1070=042E

F11 (electronics thermal overload relay 1 level) =3.60A (1HP) 3.60 X 100=360=0168
