Table 21: Braking resistors – DC1-S… 230 V nominal voltage
￫
DX-BR100 braking resistors feature a temperature switch for
protection against thermal overload.
This dry contact (N/C) can be directly integrated into the DC1-S…
variable frequency drive’s control section and work as an
external fault message (EXFLT), for example.
The DX-BR3-100 resistor does not feature a circuit-breaker.
It is inserted into the corresponding slots on the DC1-S…
variable frequency drive’s heat sinks (frame size FS2) and is
automatically protected against thermal overload as a result (heat
sink overtemperature, display:
O-t
).
The braking resistor is connected to the variable frequency
drive’s DC+ and BR terminals using the prefabricated cables.
The braking chopper is activated with parameter P-34
(
￫ section 6.6.3, ““Extended” parameter group”, page 148).
