NOTE
Before regulating the power voltage, make
sure the power has been turned off. Please set
power voltage as the possible highest voltage
for unstable power system. Take 380VAC
power system for example. If the voltage may
be up to 410Vac, 415VAC should be regulated.
For DELTA’s AC motor drive VFD Series,
please set parameter (Over Voltage Stall
Prevention) as “close” to disable over-voltage
stall prevention, to ensure stable deceleration
characteristic. For VFDB-5055, the jumper
can only be put on the position as shown in the
following figure. Do NOT remove the jumper
to other place.

VFDB Series
Braking Modules Instruction Sheet
X Preface
Thank you for choosing DELTA’s braking module. VFDB braking units are applied to absorb the motor regeneration energy when the
three-phase induction motor stops by deceleration. With VFDB braking unit, the regeneration energy will be dissipated in dedicated
braking resistors. To prevent mechanical or human injury, please refer to this instruction sheet before wiring. VFDB braking units are
suitable for DELTA AC Motor Drives VFD Series 230V/460V/575V. VFDB braking units need to be used in conjunction with BR series
braking resistors to provide the optimum braking characteristics. VFDB braking units (2015, 2022, 4030, 4045 and 5055) are approved
by Underwriters Laboratories, Inc. (UL) and Canadian Underwriters Laboratories (cUL). The content of this instruction sheet may be
revised without prior notice. Please consult our distributors or download the most updated version at

\ Basic Wiring Diagram
Operation Explanation: 1. For safety consideration, install an overload relay between the braking unit and the braking resistor. In
conjunction with the magnetic contactor (MC) prior to the drive, it can perform complete protection against abnormality.
2. The purpose of installing the thermal overload relay is to protect the braking resistor from damage due to frequent braking, or due to
braking unit keeping operating resulted from unusual high input voltage. Under such circumstance, just turn off the power to prevent
damaging the braking resistor.
3. Please refer to the specification of the thermal overload relay.
4. The alarm output terminals (RC, RA, RB) of the braking unit will be activated when the temperature of the heat sink exceeds 95
o
C. It
means that the temperature of the installation environment may exceed 50
o
C, or the braking %ED may exceed 10%ED. With this kind
of alarm, please install a fan to force air-cooling or reduce the environment temperature. If the condition not due to the temperature,
the control circuit or the temperature sensor may have been damaged. At this time, please send the braking unit back to the
manufacturer or agency for repair.

5. The AC Motor Drive and braking
unit will be electrified at the same time
while turning on the NFB (No-fuse
breaker). For the operation/stop
method of the motor, please refer to the
user manual of the AC Motor Drives
VFD Series. The braking unit will
detect the inner DC voltage of the AC
motor drive when it stops the motor by
deceleration. The extra regeneration
will be dissipated away rapidly by the
braking resistor in the form of heat. It
can ensure the stable deceleration
characteristic.
6. Besides using thermal overload relay to be the protection system and braking resistor, temperature switch can be installed on braking
resistor side as the protection. The temperature switch must comply with the braking resistor specification or contact your dealer.
] Wiring Notice
Do not proceed with wiring while power is applied to the circuit.
The wiring gauge and distance must comply with the electrical code.
The +(P), -(N) terminals of the AC motor drive (VFD Series), connected to the braking unit (VFDB), must be confirmed
for correct polarity lest the drive and the braking unit be damaged when power on.
When the braking unit performs braking, the wires connected to +(P), -(N), B1 and B2 would generate a powerful
electromagnetic field for a moment due to high current passing through. These wires should be wired separately from
other low voltage control circuits lest they make interference or mis-operation.

To prevent personal injury, do not connect/disconnect wires or
regulate the setting of the braking unit while power on. Do not touch
the terminals of related wiring and any component on PCB lest users
be damaged by extreme dangerous DC high voltage.
Inflammable solids, gases or liquids must be avoided at the
location where the braking resistor is installed. The braking
resistor had better be installed in individual metallic box with
forced air-cooling.
Connect the ground terminal to the Earth Ground. The ground
lead must be at least the same gauge wire as leads +(P), -(N).
Please install the braking resistor with forced air-cooling or
the equivalent when frequent deceleration braking is
performed (over 10%ED).
The ring terminals are suggested to be used for main circuit
wiring. Make sure the terminals are fastened before power on.
^ Definition for Braking Usage ED%
100%
T0
T1
Braking Time
Cycle Time
ED% = T1/T0x100(%)
Explanation: The definition of the barking usage ED(%) is for assurance of
enough time for the braking unit and braking resistor to dissipate away heat
generated by braking. When the braking resistor heats up, the resistance would
increase with temperature, and braking torque would decrease accordingly.
_ The Voltage Settings
1. Regulation of power voltage: the power source of the braking unit is DC voltage from +(P), -(N) terminals of the AC motor drive. It is
very important to set the power voltage of the braking unit based on the input power of the AC motor drive before operation. The setting
has a great influence on the potential of the operation voltage for the braking unit. Please refer to the table below.

2. MASTER/SLAVE setting: The MASTER/SLAVE jumper is set “MASTER” as factory setting. The “SLAVE” setting is applied to two
or more braking units in parallel, making these braking units be enabled/disabled synchronously. Then the power dissipation of each unit
will be equivalent so that they can perform the braking function completely.
The position of the jumper
The SLAVE braking application of three braking units is
shown as the above diagram. After wiring, the jumper of
first unit shall be set as “MASTER” and that of others must
be set as “SLAVE” to complete the system installation.
