HOW TO SPECIFY THE DBW TYPE:
DBW-01
WEG Braking Rated Output Current:
Module: 220 to 480 V:
DBW-01 0165 = 165 A
0240 = 240 A
0300 = 300 A
0210 = 210 A
DBW-02
0380 = 380 A
In the CFW-09 220-230 V or 380-480 V types with currents higher or equal to
180 A, dynamic braking uses the DBW-01 external braking module. For 500-
690 V and 660-690 V with currents higher or equal 100 A, dynamic braking
uses the DBW-02 external braking module.

Table 8.13 - Inverter and corresponding DBW
(1)The maximum current can be calculated by:
I = set value at P153 [V]/value of the resistor [ohms].
max
(2)The rms braking current can be calculated by:
I = I
rms max
actuation times during the most severe 5-minute cycle.
(3)The minimum resistor value of each shown model has been calculated so the
braking current does not exceed the maximum current specified in table 8.13.
For this, following parameters have been considered
- DBW-01: rated line voltage = 480 V.
- DBW-02: rated line voltage = 690 V.
- Factory Standard Value of P153.
