Fuji Electric FRENIC-Ace series - Guideline for Selecting Inverter Drive Mode and Capacity

10.4 Selecting an Inverter Drive Mode (ND/HD/HND/HHD)
10-16
10.4.2 Guideline for selecting inverter drive mode and capacity
Table 10.4-1 lists the functional differences between ND, HD, HND, and HHD modes.
If the ND mode does not satisfy the requirements in your application in view of the overload capability and
functionality, you need to select the inverter one or two ranks higher in capacity (HD/HND/HHD mode) than that of
the motor rating.
To use the inverter under the ambient temperature or carrier frequency condition changed from the factory default,
the output current rating requires derating due to the ambient temperature or carrier frequency. It is, therefore,
necessary to select the inverter unit, referring to Figure 10.4-1 through Figure 10.4-4.
