10.4 Selecting the Inverter Rating Specification (HHD/HND)
10.4.1 Precautions in making the selection
FRENIC-MEGA has a double rating specification, and so by making changes to setting values, it is possible to
switch between the Heavy Duty application HHD specification and the Normal Duty application HND specification.
When selecting the inverter capacity, consider the capacity of the motor being used and the overload
characteristics of the load, and refer to the information on HHD/HND specifications in “10.4.2 Guideline for
selecting inverter specification and capacity”.
Heavy Duty applications (HHD specification): This applies to equipment where the inverter load current
during normal operation is less than the inverter rated
current, and the load current during overload operation is
less than 150% of the rated current for 1 minute, and 200%
for 3 seconds (applications requiring frequent acceleration
and deceleration such as conveyors and cranes).
Normal Duty applications (HND specification): This applies to equipment where the inverter load current
during normal operation is less than the inverter rated
current, and the load current during overload operation is
less than 120% of the rated current for 1 minute (fans,
pumps, centrifuges, etc.).
The HND specification is for use at FRN0032G2S-2G/FRN0018G2■-4G or above.
