Specification
Input the signal when using CDBR braking units in
parallel.
Output the signal when using CDBR braking units in
parallel.
Enable/Disable contact input to disable the CDBR and
activate MA-MB-MC fault contact output.
Output signal when a fault occurs or when SB-SC is closed
(default) (example: CDBR braking unit overheating, LKEB
braking resistor unit short-circuit detection, external fault).
Wiring sequence should shut off power to the drive when
the signal is output.
Relay output
250 Vac, max.1 A
30 Vdc, max.1 A
min.5 Vdc, 10 mA
Output signal when braking unit fault is detected.
If needed, wiring sequence should shut off power to the
drive when the signal is output.
Relay output
