Using CDBR Braking Units in Parallel
Install multiple CDBR Braking Units in a master/slave configuration with a single CDBR
Braking Unit as the master as shown in Figure 21.
NOTICE: Perform all wiring and installation as instructed in Figure 21. Failure to follow specifications may
damage the drive and the CDBR braking unit.
• Set the Master/Slave Selection Switch (S2) to “Master (OUT)” on one CDBR Braking
Unit only. Set all other CDBR Braking Units to “Slave (IN)”. Refer to Master/Slave
Selection Switch (S2) on page 57 for details.
• Select the appropriate CDBR Braking Unit wire types and gauges from Table 10.
• Use shielded twisted-pair cables and keep the wiring distance between the OUT1-IN1 and
OUT2-IN2 terminals of the CDBR Braking Unit shorter than 1 meter (3.28 ft).
