Chapter 1 Functional outline
VFDB2009 series dynamic brake system is equipment (DB unit) which controls the regeneration energy for
acquiring brake power. In order to acquire brake power other than DB unit, the braking resistor (DBR) which
consumes regeneration energy as heat, and the protection thermal relay (OCRY) which carries out electrical
overload detection are required.
The brake power gained due to the loss (a total of about 10 to 15%) by inside the inverter and inside the
motor because the inverter unit doesn’t have the ability to process the suppresion energy. When making the
continuous regeneration energy under operation, or the big regeneration energy in a sudden slowdown
consume by resistance and acquiring brake power, VFDB2009 series dynamic brake system is used.
VFDB2009 series dinamic brake system has compatibility in VFDB2002 series dynamic brake system,
attachment, and an operating method. The VFDB2002 series dynamic brake system applied to the present
system is exchanged for a VFDB2009 series dynamic brake system, and a simple substance and operation to
mix are possible.
VFDB2009 dinamic brake system is designed so that the content of a lead, mercury, cadmium, sexavalent
chrome, PBB, and PBDE may be based on the RoHS instructions which EU defines in consideration of the
influence on environment.
1.1 Operation principle
The suppression energy returns to the inverter unit when motor becomes the regeneration mode. The DC voltage of
inverter rises, because the inverter doesn't provide the regenerative function to the power supply. The DB unit detects this
DC voltage, operates the switching element (IGBT) in the unit, and consumes the regenarative energy to resistor (DBR)
for power generation. If the regenerative mode became finish,DC voltage returns to a normal value, switching element
(IGBT) becomes an immovable work.
* Regenerative mode *
The case where the torque has been put out the motor to the machine`s called powering mode in the place where the
machine is driven with inverter. The motor rotation frequency rises more than the output frequency of the inverter, it enters
the state to have returned the torque from the machine to the motor under such a condition when the sudden
deceleration or a big load of GD2is naturally decelerated from this state for instance, this is called the regentive mode.

Chapter 3 Installation and Wiring
3.1 Installation
○
1Installation location of unit
The conditions in the installation location affect the life and the reliability of the inverter. Avoid using it in the
following places.
(1) If the DB unit is installed in a highly humid or dusty place, or in a place exposed to water or oil, the
circuit insulation will be deteriorated, and the life of the parts will be shortened.
(2) If the working ambient temperature is too high, the life of the capacitor and cooling fan motor will be
shortened.
(3) In a place with corrosive gas, connector contact failure, breaking of electric wires and damage of parts
may be caused.
(4) In a place with heavy vibration, connector contact failure, breaking of electric wires and damage of parts
may be caused.
(5) If the DB unit is used at an ambient temperature of 0℃or less, use a heater to increase the temperature
to more than 0℃at the start of the DB unit. After the DB unit starts, it generates heat by itself to
more than 0℃and will operate normally.
Installing the unit
To use dynamic brake unit installed in a control panel, install as follows.
DANGER [Mounting]
Improper installation may cause an electric shock or a fire.
(1) Installation direction
VFDB2009 DB unit turns a main circuit terminal down and attaches it perpendicularly. If installed
horizontally, it will not be ventilated sufficiently and will be overheated. Enogh consideration must be
taken to the routes of suction and exhaust of air.
Moreover, the cooling fan of DB unit (VFDB2009-200F) with a cooling fan inhales from the bottom, and
exhausts air to the top. Keep sufficient space above the unit so that ventilation is not prevented by
wiring dusts, etc.
When installing VFDB2009 DB unit, keep cooling spaces as shown in the following figure3.1.
When VFDB2009 DB unit is installed in a control panel, ventilate the panel to keep the temperature in
the panel within 50℃.󲥵If the ambient temperature is high, the reliability of the inverter will be
degraded.󲥶
(2) Cautions
Surely exhaust the heat generated by the DB unit to the outside of the panel. Prevent the exhaust from
the DB unit to circulate in the panel.
Install the resistor on the outside of the panel as much as possible.
Avoid using the DB unit in a considerably coarse environment.

3.2 Connection
A maximum of six sets of parallel runs are possible for VFDB2009 series dynamic brake system. Please
keep in mind that control wiring differs in single operation and parallel operation. Moreover, it is necessary
to change a setup of DB unit in accordance with wiring. refer to "5.2.2 Set-up of single operation or
Master/Slave system paralle operation" for change of a setup. In addition, a parallel operation with
VFDB2002 series is also possible for this VFDB2009 series. Refer to "8.3.2 connection method" for the wiring
at the time of a parallel run with VFDB2002 series.
The parallel operation of DB unit of our company has adopted “Master & Slave system.” “Master & Slave
system” sets to Master DB unit which each DB unit performed DB operation detection and carried out DB
operation detection previously, and takes out instructions of ON/OFF of switching device (IGBT) to other
parallel units. Figure 3.3 shows the connection method and the wiring between each DB unit becomes the
same.
DB unit set up by Master unit performs DB operation detection, and "Master & Slave system" of VFDB2002
series takes out instructions of ON-OFF of switching device (IGBT) of a slave unit. Even when VFDB2009
series DBunit is applied, "Master & Slave system" of VFDB2002 series is possible. Refer to Figure 8.1 for the
connection method in that case.
In accordance with the power supply voltage system of an inverter, a DB unit setup is required before use.
When DB unit is used by mistaken setup, there is fear of breakage and unusual operation. Refer to "5.2.1.
Change of a power supply voltage" and "5.4.3 F20 (Power supply voltage selection and Master/Slave
selection and Station number set-up mode) for a setup of a power supply voltage system.

Chapter 5 Operation
VFDB2009 series Dynamic brake unit operates in the power supply of the middle D.C. voltage of the
inverter. The DB unit becomes a waiting state if the inverter run signal(52MA) is input after the
inverter-middle D.C. voltage rises, and LED “RUN" (Light Emitting Diode) lights. Main switching device(IGBT)
operates when the middle D.C. voltage rises by the regeneration of the inverter, and it rises up to the voltage
set to the DB operating point,and LED “DB" lights. At this time, brake resistor connected to DB unit consumes
regeneration energy, and if inverter-middle D.C. voltage turns into below the voltage that stops DB operation,
a switching device is turned off.

If the power supply of an inverter is turned on, the inverter-middle D.C. voltage will rise and D.C. voltage will
be displayed on the display for indication of DB unit. Setup and adjustment of DB unit are possible by
operating a display for indication.
It changes from the display mode of D.C. voltage to a setup and adjustment of DBunit to setting mode. The
mode can be changed by pushing "FNC/SET" and "UP", and the "DOWN" button.
※"△" in a figure expresses the "UP" button, and "▽" expresses the "DOWN" button.
●Status display 󳮕LED󳮖

Figure 5.3 The mode change state of a display for indication
If the "FNC/SET" button is pushed during the display of direct-current voltage, it will shift to setting mode
"F10" and LED"FNC/SET" will light up simultaneously. If "UP" or the "DOWN" button is pushed into setting
mode, it will shift to setting mode (F10-F40), and if the "FNC/SET" button is pushed, it will shift to the setting
item in each setting mode.
※If LED"RUN" lights up in set-up mode (DB operation instruction ON), it will switch to D.C. voltage display
mode compulsorily. Moreover, even if it pushes the "FNC/SET" button during lighting of LED"RUN", it does
not switch to setting mode.

5.2 Set-up before operation
Please be sure to perform the following setup before using DB unit. DB unit is common use in the power
supply voltage (200V series /400V series) of inveretr and single/parallel operation. Since power supply
voltage is set as 400V series and the mode of operation is set as single operation at the time of shipment, a
setup is changed according to application.
5.2.1 Change of a power supply voltage
󳠟Before turing on the power supply of an inverter,please switch connector CN2 and CN3 of
VFDB2009-Z PC board, according to the power supply voltage of the inverter to be used.
Connector is switched corresponding to the power
supply voltage of the inverter to be used.
