All brake resistors feature a temperature switch for protection
against thermal overload.
This potential-free contact (N/C) can be directly integrated into
the DC1 variable frequency drive’s control section and work as
an external fault message (control terminal 10, DI5, parameter
P9-08 = 5).
Exception:
The DX-BR3-100 resistor does not feature a circuit-breaker.
It is inserted into the corresponding slots on the DC1 variable
frequency drive’s heat sinks (frame sizes FS2 and FS3) and is
automatically protected against thermal overloads as a result
(heat sink overtemperature, display:
O- t
).
