Installation Manual
Table 9 CDBR Braking Unit Control Circuit Terminals
Terminal
Block
<1> Digital Input-SB, SC. Powered by internal 24 Vdc LVLC source. When using an external power supply, it shall be
UL Listed Class 2 power source only or equivalent.
Terminal No.
Terminal Name
Specification
TB1
IN1
Slave Input
Input the signal when using CDBR braking units in
parallel.
IN2
OUT1
Master Output
Output the signal when using CDBR braking units in
parallel.
OUT2
Enable Input
Enable/Disable contact input to disable the CDBR and
activate MA-MB-MC fault contact output.
TB2
MA
Fault Contact Output
(N.O.)
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

Short-Circuit Detection
Output (N.O.)
Output signal when braking unit fault is detected.
If needed, wiring sequence should shut off power to the
drive when the signal is output.
