Fuji Electric FRENIC MEGA G2 Series - 4.5 Switching the Applicable Motor Rating (HHD;HND Specifications)

4.5 Switching the Applicable Motor Rating (HHD/HND Specifications)
4-6
4.5 Switching the Applicable Motor Rating (HHD/HND Specifications)
By switching from the factory default HHD specification to the HND specification on three-phase 200V series and
three-phase 400V series inverters, they can be used with a motor reference rated current of one to two ranks
higher. However, the overload capability will drop.
Double key operation ( key + / keys) is required to change function code F80 data.

 Some models are incompatible with the HND specification depending on the inverter rated voltage and
capacity. Please refer to Chapter 12 “SPECIFICATIONS”.
HHD/HND specification inverters are subject to restrictions on the function code data setting range and internal
processing as listed below.

Switching between the drive modes does not automatically change the motor rated capacity (P02*) to the one
suitable for the rank-changed motor, so configure the P02* data to match the applied motor rating as required.
