◆ About this Product

Installing a CDBR Braking Unit or an LKEB Braking Resistor Unit helps dissipate
regenerative energy from the motor. This is useful in applications that require sudden
deceleration and frequent stops and it allows for shorter deceleration times in applications
running heavy loads.

◆ Applicable Models

■ CDBR Braking Unit

The CDBR Braking Unit is designed for use with the drive models in Tabl e 1. Contact
Yaskawa or your Yaskawa agent for other drives. Also may be used as a replacement for
CDBR spec.B type. Contact your Yaskawa representative for more information.

◆ Wiring the CDBR Braking Unit

■ Wiring Precautions

Prior to installing the CDBR Braking Unit or the LKEB Braking Resistor Unit, wire the
drive, make the necessary connections to the drive terminals, and verify that the drive
functions normally without the option installed. Refer to the Quick Start Guide packaged
with the drive for information on removing the digital operator and front covers, wiring, and
connecting the drive.

WARNING! Electrical Shock Hazard. Be sure to ground the drive ground terminal (200 V class: ground to
100 Ω or less; 400 V class: ground to 10 Ω or less; 600 V class: ground to 10 Ω or less). Improper
equipment grounding could result in death or serious injury by contacting ungrounded electrical equipment.

WARNING! Fire Hazard. When installing dynamic braking options, perform all wiring exactly as specified in
the wiring diagrams provided. Failure to do so can result in fire.

WARNING! Electrical Shock Hazard. Mount the LKEB Braking Resistor Unit on a grounded metallic plate.
When it cannot be mounted on a grounded metallic plate, connect a ground wire from a mounting LKEB
screw to earth ground. Improper equipment grounding could result in death or serious injury.

NOTICE: Insulate shields with tape or shrink tubing to prevent contact with other signal lines and
equipment. Improper wiring practices could result in drive or equipment malfunction due to short circuit.

NOTICE: Do not solder the ends of wire connections to the option. Soldered wiring connections can loosen
over time. Improper wiring practices could result in option malfunction due to loose terminal connections.

Note: 1. Keep ground cables as short as possible and ensure cabling complies with local codes.

2. Separate CDBR Braking Unit and LKEB Braking Resistor Unit wiring from control wiring.

3. Keep wiring distance between the CDBR Braking Unit and LKEB Braking Resistor Unit shorter than

10 meters (32.80 feet) and keep wiring between the drive and the CDBR Braking Unit shorter than 5
meters (16.40 feet).

■ Wiring Procedure

WARNING! Fire Hazard. Tighten terminal screws to the specified tightening torque. Loose electrical
connections could result in death or serious injury by fire due to overheating. Tightening screws beyond the
specified tightening torque may cause erroneous operation, damage the terminal block, or cause a fire.
Refer to Wire Gauge and Torque Specifications on page 51 for details.

1. For all CDBR wiring refer to Table 11 for wire gauge and torque specifications and

refer to Figure 21 for the drive and option connection diagram

2. Connect ground wiring to the ground terminals. Refer to Tabl e 9 for descriptions of

CDBR Braking Unit Main Circuit Terminals.

3. Connect main circuit wires to the main circuit terminals B1, B2, and . Refer to

Table 9 for descriptions of CDBR Braking Unit Main Circuit Terminals.

4. Connect control circuit wiring to the control circuit terminals. Refer to Table 10 for

details on CDBR braking unit control circuit terminals.

5. Ensure all main circuit and control circuit wires exit through the openings in the

Figure 17

bottom of the CDBR Braking Unit enclosure.

Figure 17 Wiring the Terminals

6. Reattach the bottom and front cover. After wiring to the CDBR Braking Unit and

drive is complete, double-check all connections before reattaching covers.

■ Connection Diagram

WARNING! Fire Hazard. To prevent electrical fire, follow the connection diagrams. Failure to comply may
result in serious injury or death.

Figure 21

<1> Set L8-55 to 0 to disable the protection function for the internal braking transistor when using a regenerative unit

or another type of dynamic braking option in lieu of the internal braking transistor. If the protection function is
enabled under these conditions, it may cause a braking resistor fault (rF). This is not available for Varispeed
G7-series.

<2> Set L3-04 to 0 to disable Stall Prevention when using a regenerative converter, a regenerative unit, or a dynamic

braking option. If the function is enabled under these conditions, the drive may not stop within the specified

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.

◆ Setting the CDBR Braking Unit

After completing drive and CDBR Braking Unit wiring, confirm the setting of the CDBR
Braking Unit onboard switches.

WARNING! Electrical Shock Hazard. Do not remove covers or touch the circuit boards while the power is
on. Failure to comply could result in death or serious injury.

CAUTION! Burn Hazard. Do not touch a hot heatsink. Failure to comply could result in minor or moderate
injury. To prevent burns, wait at least 15 minutes after power off and ensure the heatsink has cooled down.

■ Braking Unit Enable Input Setting (S1, S4, S5 DIP Switch)

The braking unit set to the default setting will turn on only if SB-SC Enable Input is applied.

DIP switch S1 is used to select SINK or SOURE mode for the SB-SC Enable Input. An
external 24 Vdc (Class 2) power supply is required for SOURCE mode.

DIP switch S4 is used to select the contact type N.O or N.C, that will activate the SB-SC
Enable Input.

DIP switch S5 is used to enable or disable the Fault Contact Output MA-MB-MC when
SB-SC Enable Input is activated.

DIP switch default settings:

S1 = SINK Mode
S4 = N.O., setting A
S5 = Enable, setting 2

Note: DIP switch S5 is available from Rev. B or later.

■ Master/Slave Selection Switch (S2)

The default setting of DIP switch S2 is OUT (Master). Change the switch position only
when operating the unit as a slave device.

Only the properly configured master CDBR should have DIP switch S2 set to OUT (master).
All other units in the circuit must have DIP switch S2 set to IN (slave). Refer to Using

CDBR Braking Units in Parallel on page 52 for details.

■ CDBR Braking Start Voltage Rotary Switch (S3)

Set the braking start level voltage level rotary switch S3 to match the power supply of the
main circuit. The default rotary switch S3 setting is 9. Refer to Table 14 for details on rotary
switch S3 position and braking start voltage.

Note: 1. The setting does not typically require adjustment.

2. Consider the amount of voltage fluctuation in the DC bus when changing rotary switch S3 setting

values. If the starting voltage is incorrectly set to a low value, applying power to the drive may active
the CDBR and overheat the braking resistor.

3. Be sure to firmly click the switch into the proper position in accordance with the incoming power

<1> Refer to the drive manual for details on Normal Duty (ND)/Heavy Duty (HD).
<2> Refers to a motor decelerating with constant torque. Applications requiring braking while operating at constant

speed will reduce the duty factor.

<3> Applications with a relatively large amount of regenerative power (elevators, etc.) may require more braking

power than is possible with only the standard CDBR Braking Unit and LKEB Braking Resistor Unit. Contact
Yaskawa for information if braking torque exceeds the value shown.

<4> Assumes the use of a single CDBR Braking Unit. The CDBR Braking Unit should have a resistance higher than

the minimum connectable resistance value and be able to generate enough braking torque to stop the motor.
<5> Contact your Yaskawa representative for availability.
<6> Contact Yaskawa or your Yaskawa agent for selection of braking resistor units.
<7> Make the connection braking resistor unit to parallel the resistors to change resistance from 42.5 Ω to 21.25 Ω.
