CDBR-B Installation Instructions
Preface
A Dynamic Braking Unit and Resistor are used to dissipate regenerative energy from the motor.
Whenever an excited motor is operated in the negative slip region or is subjected to an overhauling
load, the motor will behave as an induction generator. In this mode, energy will actually flow from the
motor back into the drive.
This will cause the DC bus voltage to rise. When the DC bus voltage reaches a certain level, the
Dynamic Braking Unit will activate. The Dynamic Braking Unit will shunt the regenerative energy
away from the DC bus capacitors and will dissipate it as heat in the DB resistors. Since the
regenerative energy is dissipated in the resistors, the overvoltage (OV) trip is prevented; thus the
motor remains excited and continues to produce braking torque.

Installation
Mounting/Wiring
1. Disconnect all electrical power to the drive.
2. Remove drive front cover.
3. Verify that voltage has been disconnected by using a voltmeter to check for voltage at the
incoming power terminals.
4. The braking unit and braking resistor emit heat during operation. Select a mounting location
away from other heat emitting devices or devices that are heat sensitive. To guarantee proper
air-flow for cooling, the braking unit should not be mounted any closer to external devices than
1.18 in. (30mm) on either side and 3.94 in. (100mm) of the top and bottom. Select mounting
locations so that the wiring distances between the drive and the braking unit is less than 16.4
feet (5m), and the distance between the braking unit and the braking resistor is less than 32.8
feet (10m).
5. Make connections between the drive, braking unit(s), and braking resistor(s) according to Figure
1 or Figure 2 (multiple units).
Grounding
6. The enclosure of the braking unit should be grounded. If the braking unit cannot be mounted in a
grounded enclosure, ground it by using a lead from the mounting screw of the unit.
7. Grounding resistance of the braking unit should be 100 ohms or less.
8. Use a grounding lead conforming to your National Electric code.
Adjustments
9.
a) It may be necessary to change the appropriate input voltage selection. This determines
the voltage that the dynamic braking unit will turn on. See Figure 3 or 4 and set the jumper
to the nominal three phase supply voltage. Table 1 indicates the DC voltage level that the
braking unit will turn on for different jumper settings. Failure to set the jumper at the
nominal voltage can cause premature failure of the braking unit.
b) If two or more braking modules are applied, ensure that unit #1 is set as the MASTER
while the other unit(s) are set for SLAVE. See Figure 1 or 2 (depending on number of
braking modules). If only one braking unit is applied, verify that the jumper is set to
MASTER.
10. The installation of the braking unit may require programming of the drive.
a) For an IMPULSE®•G: Program Sn-05 to xx1x, which disables stall prevention during
deceleration.
b) For an IMPULSE®•G+: Program Sn-07 to xx1x, which disables stall prevention during
deceleration.
c)
For an IMPULSE®•G+ and VG+ Series 2: Program L3-04 to 0, which disables stall
prevention during deceleration.
d) For an IMPULSE®•G+ and VG+Series 4: Program L08-55 to 0, which disables the RF
fault.

Braking Module Test Procedure
WA R N I N G
Do NOT touch any circuit components while AC main power is on or immediately after main AC
power is disconnected from the unit. You must wait until the red “CHARGE” lamp is
extinguished. It may take as long as 10 minutes for the charge on the main DC bus capacitors to
drop to a safe level. Failure to adhere to this warning could result in serious injury.
1. Remove the cover and check IPCB for physical damage.
2. Using a Digital Multimeter, set the Diode Check function, perform static checks on the main
transistor module, 1TRM.
For CDBR-2045B, 2110B, 4090B, 4220B, 5037B, 5110B, and 5300, check the following:
•
Place the positive lead on terminal (-) and the negative lead on terminal (-O). This will check
the collector to emitter junction for a short circuit. A reading of between 0.200V and 0.250V
indicates a good reading.
•
Place the positive lead on terminal (-O) and the negative lead on terminal (+O). This will
check the diode connected to the collector for a short circuit. A reading of between 0.200V
and 0.375V indicates a good reading.
For CDBR-2022B and 4045B, check the following:
•
Place the positive lead on terminal (-) and the negative on terminal (-O). This will check the
collector to emitter junction for a short circuit. A reading of “OL” indicates a good reading.
•
Place the positive lead on terminal (-O) and the negative lead on terminal (+O). This will
check the diode connected to the collector for a short circuit. A reading of approximately
0.5V indicates a good reading.

3. Remove connector 3CN on 1PCB and place the ohmmeter leads on terminals 1 and 2 of the
connector. The meter should read infinite Ohms. (Normally Open Thermal Relay (1THG).
Replace connector 3CN.
4. Place the 4CN jumper on 1PCB to the “Master” position.
5. 230V Models
Verify that the Power Supply Voltage Selection Jumper is set to 230V.
With a variable DC power supply, which is capable of producing 400 VDC output, apply the DC
voltage to terminals (+) and (-). Slowly increase the voltage to approximately 50V, at which time
the Charge LED on 1PCB should illuminate. With a DC Voltmeter, monitor terminals (+O) and
(-O), and continue to increase the DC voltage to 380 VDC, at which time you should see the DC
Voltmeter turn on to read the 380 VDC applied voltage, and the Brake LED on 1PCB should illuminate. At this same time, you should also read 15 VDC across terminals 5(+) and 6(-), which
indicates that the output, to activate a slave CDBR, has turned on.
460V Models
Verify that the Power Supply Voltage Selection Jumper is set to 460V.
With a variable DC power supply, which is capable of producing 800 VDC output, apply the DC
voltage to terminals (+) and (-). Slowly increase the voltage to approximately 50V, at which time
the Charge LED on 1PCB should illuminate. With a DC Voltmeter, monitor terminals (+O) and
(-O), and continue to increase the DC voltage to 780 VDC, at which time you should see the DC
Voltmeter turn on to read the 780 VDC applied voltage, and the Brake LED on 1PCB should illuminate. At this same time you should also read 15 VDC across terminals 5(+) and 6(-), which
indicates that the output, to active a slave CDBR, has turned on.
575V Models
Verify that the Power Supply Voltage Selection Jumper is set to 575V.
With a variable DC power supply, which is capable of producing 1000 VDC output, apply the DC
voltage to terminals (+) and (-). Slowly increase the voltage to approximately 50V, at which time
the Charge LED on 1PCB should illuminate. With a DC Voltmeter, monitor terminals (+O) and
(-O), and continue to increase the DC voltage to 950 VDC, at which time you should see the DC
Voltmeter turn on to read the 950 VDC applied voltage, and the Brake LED on 1PCB should illuminate. At this same time you should also read 15 VDC across terminals 5(+) and 6(-), which
indicates that the output, to active a slave CDBR, has turned on.
6. Remove power from terminals (+) and (-).
7. Place the jumper on 4CN on1PCB to the “Slave” position.
8. Apply power (325 VDC for 200V models, 650 VDC for 400V models, and 812 VDC for 500V
models) to terminals (+) and (-). Using a separate DC power supply, apply 7 VDC to terminals
1(+) and 2(-) on 1PCB. This 7 VDC signal should cause the main transistor 1TRM to turn on and
you should read the applied DC Bus Voltage across terminals (+O) and (-O), and the Brake LED
on 1PCB should illuminate.
9. With power still applied to terminals (+) and (-), monitor terminals 3 and 4 on 1PCB with an
Ohmmeter. This meter should read Infinite Ohms. Place a jumper across the terminal switch
(pins 1 and 2 on 3CN), which should cause the Fault Relay to change state, and 0 Ohms should
read on the Ohmmeter.
10. Remove the terminals (+) and (-) and return the 4CN jumper on 1PCB back to the “Master”
position.
