■ Using CDBR Braking Units in Parallel
Be sure to install multiple CDBR Braking Units in a master/slave configuration with a single
CDBR Braking Unit as the master. Figure 22 illustrates how to wire CDBR Braking Units
in parallel.
NOTICE: Perform all wiring and installation as instructed below. 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 56 for details.
• Follow wire specifications when connecting the CDBR Braking Unit. Refer to Table 11
for details.
• 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.
