WEG CFW-11W, Addendum, Page: 8 / 42

General Information
CFW11W | 1-5
NOTE
!
In order to assemble the complete drive, several additional items are needed, such as: input
rectifier, fuses on the DC power supply for each UP11, external pre-charge circuit and input
reactance with minimum input impedance of 3% when it is a 6-pulse rectifier.
NOTE
!
It is not necessary to add the ground fault CT to the drive, since the UP11s have their own
protection.
1.3. HOW TO SPECIFY THE MODEL
In order to specify the model of the CFW-11W, replace the smart code values with the desired rated supply
voltage and rated output current in the respective fields, for operation under normal duty cycle (ND), as shown in
the example:
Table 1.1: Smart Code
Inverter Model Option Items Available
Refer to the model list of the CFW-11W
series in chapter 5, which also contains
the technical specifications of the
inverters.
Refer to chapter 7 of the CFW11M user manual
for further details on the option items.

(*)This field (voltage) represents the three-phase input voltage on the rectifier that feeds DC voltage to the CFW-11W. The rectifier is not part
of the
CFW11W.
NOTE
!
For the other fields of the code, refer to the CFW-11M user manual.
E.g.: CFW11W0640T6SZ corresponds to a standard CFW-11W inverter with 640-A three-phase output and
input supply voltage of 500 - 690 V. The options for the inverter rated current under normal duty (ND) cycle are
available in Table 1.2 below:
