REGENERATIVE BRAKING OPERATION
When the CFW-11W is used in a drive as a regenerative converter (CFW-11W RB), consider the following
information:
Line 380-480 V:
Consider the same losses indicated in
Line 500-690 V:
The CFW-11W RB (line 500-690 V) has switching frequency of 2.5 kHz, instead of 2.0 kHz, as
presented in
Due to the higher switching frequency, the losses in this converter are also higher. Consider an increase
of 17% in the losses of the inverter.
All lines:
Use the same mechanical data presented in this addendum.
Data about control connections and electrical installation, refer to the CFW-11M RB user manual.
LCL filter for the converters, contact WEG.
