- Inverter and corresponding DBW
(1)
The maximum current can be calculated by:
I
max
= set value at P153 [V]/value of the resistor [ohms].
(2)
The rms braking current can be calculated by:
I
rms
= I
max
.
t
br
[min]
where t
br
corresponds to the sum of the braking
5
actuation times during the most severe 5-minute cycle.
(3)
The minimum resistor valueof each shown modelhas been calculated so the
brakingcurrent does notexceed the maximum currentspecified 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.
8.10.3
Dynamic Braking module -
DBW-01 and DBW-02
In the CFW-09 220-230 V or 380-480 V types with currents higher or equal to
180A, 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.
