7.16.4 Derating of DC-bus Voltage
The drive can be used without derating up to 1025 V DC. For DC-bus voltages higher than 1025 V DC, current must be derated according
to the diagram.

7.17 Modulator Types
The following are the available modulator types for AFE, GC, and INU modules. For more detailed descriptions and instructions on
modulator type selection, see the iC7 series application guides.
Modulator types for AFE and GC
Modulator type 4 – CMRPWM
l The default modulator type for AFE. This modulator can be used in the AFE to minimize motor voltage spikes. The modulator cannot
be used when independent paralleling is used (when Paralleling sync. Mode is enabled).
