Preface
Thank you for choosing DELTA’s high-performance VFD-BW Series. The VFD-BW Series is
manufactured with high-quality components and materials and incorporates the latest microprocessor
technology available.
This manual is to be used for the installation, parameter setting, troubleshooting, and daily
maintenance of the AC motor drive. To guarantee safe operation of the equipment, read the following
safety guidelines before connecting power to the AC motor drive. Keep this operating manual at hand
and distribute to all users for reference.
To ensure the safety of operators and equipment, only qualified personnel familiar with AC motor
drive are to do installation, start-up and maintenance. Always read this manual thoroughly before
using VFD-BW series AC Motor Drive, especially the WARNING, DANGER and CAUTION notes.
Failure to comply may result in personal injury and equipment damage. If you have any questions,
please contact your dealer.
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
DANGER!
1. Ensure that VFD-BW is grounded in a correct way before putting it into use.
2. AC input power must be disconnected before any wiring to the AC motor drive is made.
3. A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power
has been turned off. To prevent personal injury, please ensure that power has been turned off
before opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe
voltage levels.
4. Never reassemble internal components or wiring.
5. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the
input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and
W/T3 directly to the AC mains circuit power supply.
6. Ground the VFD-BW using the ground terminal. The grounding method must comply with the
laws of the country where the AC motor drive is to be installed. Refer to the Basic Wiring
Diagram.
7. VFD-BW series is used only to control variable speed of 3-phase induction motors, NOT for 1-
phase motors or other purpose.
8/16/2019 Vfd Bw Manual
5/251
8. VFD-BW series shall NOT be used for life support equipment or any life safety situation.
WARNING!
1. DO NOT use Hi-pot test for internal components. The semi-conductor used in the AC motor
drive is easily damaged by high-pressure.
2. There are highly sensitive MOS components on the printed circuit boards. These components
are especially sensitive to static electricity. To prevent damage to these components, do not
touch these components or the circuit boards with metal objects or your bare hands.
3. Only qualified persons are allowed to install, wire and maintain AC motor drives.
CAUTION!
1. Some parameter settings will cause the motor to run immediately after applying power.
2. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight,
high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic
particles.
3. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or
electric shock.
4. To prevent personal injury, please keep children and unqualified people away from the
equipment.
5. When the motor cable between the AC motor drive and motor is too long, the layer insulation of
the motor may be damaged. Please use a frequency inverter duty motor or add an AC output
reactor to prevent damage to the motor. Refer to appendix B Reactor for details.
6. The rated voltage for the AC motor drive must be ≤ 480V for 460V models and the mains
supply current capacity must be ≤ 5000A RMS (≤10000A RMS for the ≥ 40hp (30kW) models).

2.4 Wiring
After removing the front cover, check if the power and control terminals are clear of debris. Be sure
to observe the following precautions when wiring.
2.4.1 Basic Wiring
Make sure that power is only applied to the R/L1, S/L2, T/L3 terminals. Failure to comply
may result in damage to the equipment. The voltage and current should lie within the range
as indicated on the nameplate.
Check the following items after completing the wiring:
1. Are all connections correct?
2. No loose wires?
3. No short-circuits between terminals or to ground?
A charge may still remain in the DC bus capacitors with hazardous voltages even if the power has
been turned off. To prevent personal injury, please ensure that the power is turned off and wait ten
minutes for the capacitors to discharge to safe voltage levels before opening the AC motor drive.
DANGER!
1. All the units must be grounded directly to a common ground terminal to prevent electric shock,
fire and interference.
2. Only qualified personnel familiar with AC motor drives are allowed to perform installation, wiring
and commissioning.
3. Make sure that the power is off before doing any wiring to prevent electric shocks.
Basic Wiring Diagrams
Users must connect wires according to the circuit diagrams on the following pages. Do not plug a
modem or telephone line to the RS-485 communication port or permanent damage may result. The
pins 1 & 2 are the power supply for the optional copy keypad PU06 only and should not be used for
RS-485 communication.

Powersupply
Please follow the specific powersupply requirements shown in
Appendix A.
Fuse/NFB(Optional)
There may be an inrush currentduring power up. Please check thechart of Appendix B and select thecorrect fuse with rated current. Use ofan NFB is optional.
Magneticcontactor(Optional)
Please do not use a Magneticcontactor as the I/O switch of the ACmotor drive, as it will reduce theoperating life cycle of the AC drive.
Input ACLine Reactor (Optional)
Used to improve the input powerfactor, to reduce harmonics andprovide protection from AC linedisturbances (surges, switchingspikes, short interruptions, etc.). ACline reactor should be installed whenthe power supply capacity is 500kVAor more or advanced capacity isactivated .The wiring distance shouldbe≤ 10m. Refer to appendix B fordetails.
Zero-phaseReactor(Ferrite CoreCommonChoke)(Optional)
Zero phase reactors are used toreduce radio noise especially whenaudio equipment is installed near theinverter. Effective for noise reductionon both the input and output sides. Attenuation quality is good for a widerange from AM band to 10MHz. Appendix B specifies the zero phasereactor. (RF220X00A)
EMI filter(Optional)
To reduce electromagneticinterference, please refer to Appendix
B for more details.
BrakeResistor(Optional)
Used to reduce the deceleration timeof the motor. Please refer to the chartin Appendix B for specific brakeresistors.
Output ACLine Reactor (Optional)
Motor surge voltage amplitudedepends on motor cable length. Forapplications with long motor cable(>20m), it is necessary to install areactor at the inverter output side.

P2-N, P2/B1-N [+2-(-),+2/B1-(-)] Connections for external brake unit (VFDB series)
Earth connection, please comply with local regulations.
Mains power terminals (R/L1, S/L2, T/L3)
Connect these terminals (R/L1, S/L2, T/L3) via a non-fuse breaker or earth leakage breaker
to 3-phase AC power for circuit protection. It is unnecessary to consider phase-sequence.
It is recommended to add a magnetic contactor (MC) in the power input wiring to cut off
power quickly and reduce malfunction when activating the protection function of AC motor
drives. Both ends of the MC should have an R-C surge absorber.
Do NOT run/stop AC motor drives by turning the power ON/OFF. Run/stop AC motor drives
by RUN/STOP command via control terminals or keypad. If you still need to run/stop AC
drives by turning power ON/OFF, it is recommended to do so only ONCE per hour.
Do NOT connect 3-phase models to a 1-phase power source.
Control circuit terminals (U, V, W)
When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor
terminals U/T1, V/T2, and W/T3, respectively, the motor will rotate counterclockwise (as
viewed on the shaft end of the motor) when a forward operation command is received. To
permanently reverse the direction of motor rotation, switch over any of the two motor leads.
