Introduction
Congratulations on your purchase of the DELTA VFD-A series AC motor drive. The VFD series is a
high-performance / low noise general-purpose AC motor drive, manufactured using high-quality
components and incorporating the latest micro-processor technology available.
The purpose of this chapter is to provide specific, yet simple information to unpack, install, and
operate the AC drive. This chapter contains information on the following:

Identification of Components and Accessories
Getting Started
This manual will help in the installation, parameter setting, troubleshooting, and maintenance of
the AC drive. To guarantee safe operation of the equipment, read the following safety guidelines
before connecting the drive to the AC power line. Keep this manual in a place where it is available
to all users for their reference.
!
Warning! To avoid personal injury, do not remove the cover of the AC motor drive until all of the
digital keypad “DISPLAY LED” lamps are off. The DC-link capacitor remains charged with a
hazardous voltage even after input power is removed.
!
Warning! Do not connect or disconnect wires and connectors while power is applied to the circuit.
All connections should be performed by qualified personnel.
Attention: Grounding the VFD-A drive is done by connecting the Earth Ground to the drive
!
ground terminal.
Attention: The final enclosure for operating the AC Motor Drive must comply with the
!
requirements of EN 50178. ( Live parts shall be arranged in enclosures or located behind barriers
that meet at least the requirements of the Protective Type IP20; Top surfaces of enclosures or
barriers that are easily accessible shall meet at least the requirements of the Protective Type IP40
)
Caution: There are highly sensitive components on the printed circuit boards. These components
!
are especially sensitive to ESD (electrostatic discharge). To avoid damage to the drive, do not
touch components or the circuit boards until all static control precautions have been taken.
!
Caution: Never connect the main circuit output terminals U, V, and W directly to the AC main
circuit power supply as this will damage the drive.
!
Caution: Do not apply the antirust to screws for fastening drives; Please clean the drives and
screws with dry cloth or alcohol, not with synthetic cleaner. Fasten the screws with washers and
rated torque lest the enclosure corners of drives be distorted.
This manual is for DELTA AC Motor Drive VFD-A and VFD-H Series. For the frequency in Pr.03,
Pr.04, Pr.06, Pr.16, Pr.17, Pr.18, Pr.19, Pr.20, Pr.21, Pr.22, Pr.23, Pr.36, Pr.37, Pr.47, Pr.67, Pr.68
and Pr.69, VFD-A Series can be regulated up to 400Hz and VFD-H Series up to 1500Hz.

Receiving, Storage and Transportation
The AC motor drive has gone through rigorous quality control tests at the factory before shipment.
After receiving the AC drive, check for the following.
Receiving
Check to make sure that the package includes an AC drive, the User Manual, dust covers
and rubber bushings.
Inspect the unit to insure it was not damaged during shipment.
Make sure that the part number indicated on the nameplate corresponds with the part
number of your order.
Storage
The AC Drive should be kept in the shipping carton before installation. In order to retain the
warranty coverage, the AC drive should be stored properly when it is not to be used for an
extended period of time. Some storage suggestions are:
Store in a clean, dry location.
Store within an ambient temperature range of -20°C to +60°C.
If possible, store in an air-conditioned environment where the relative humidity is less
than 95%, non-condensing.
Do not store the AC drive in places where it could be exposed to corrosive gases.
Do not store the AC drive on a shelf or on an unstable surface.
Transportation
Temperature: -25°C to +70°C; R.H.: 0% to 95%; Air Pressure: 70kPa to 106kPa.

(4) Attention:
!
The user must provide a circuit breaker or disconnect switch and fuses in accordance
with all applicable electrical codes.
Make sure that the leads are connected correctly and the AC drive is properly
grounded. (Ground leads should be at least the same size wire as the input leads R, S,
and T.)
Use ground leads that comply with AWG standards. Make the length of these ground
leads as short as possible.
Should several AC drive units be installed side by side, all the units should be
grounded directly to the ground poles. Do not form a loop with the ground leads.
Make sure that the power source supplies the correct voltage and is capable of
supplying the required current to the AC drive. Refer to specification for “Rated AC
Input Power.” Motor Voltage should match the line voltage.
When power is applied to the AC drive, the DC bus charge indicator LED will be on.
For single phase applications, the AC input line can be connected to any two of the
three input terminals R, S, T. A single phase VFD-A drive can be powered from three
phase as well as single phase.
Note: This drive is not intended for use with single-phase motors.
When the AC drive output terminals U, V, and W are connected to the motor terminals
U, V, and W, respectively, the motor will rotate counter-clockwise (viewed from the
shaft of the motor as shown below) if a forward operation command is entered (FWD
lamp is ON).
Forward
running
To reverse the direction of rotation, interchange any two connections of the three
motor leads.
The control lines and power lines (R,S,T;U,V,W;P,N,B1,B2) should be separated and
avoid parallel wiring lest it should generate noise and cause mis-operation.
Caution: Do not attach or remove wiring or connectors when power is applied to the
!
AC drive. Do not monitor the signals at any point on the circuit board while the AC
drive is in operation.
Caution: Do not connect the AC input to any of the U, V, W terminals, as this will
!
damage the AC drive.

This completes the operation mode selection. Verify your operation mode works correctly,
then proceed to the next section for motor connection and initial operation.
Initial Operation – Setting Parameters and connecting the Motor.
1) Verify Minimum and Maximum Output Frequency Settings (Pr. 08 and 03) are
correct for your application.
2) Verify the Motor Stop Method (Pr.02) is correct for your application. If set to
“Ramp to Stop”, then verify the Accel/Decel Time Settings (Pr.10 and 11) are
correct for your application.
3) Disconnect and lock out all incoming power to the AC drive. A DC bus voltage
may be present at the terminal block for up to 1 minute after the power has been
removed from the drive.

4) Connect the motor to the terminals U, V, and W
5) Connect all applicable control wiring. Refer to the Control Circuit Wiring diagram
in Chapter 2.
6) Reconnect the incoming power to the AC drive.
7) Check for correct motor shaft rotation (counter clockwise when viewed from the
shaft).
8) Verify the Stop command is functioning by pressing the Stop Key on the Digital
Keypad or using your Control Terminal Stop method.
This completes the basic start-up. Depending on the application, some parameter values
may need to be modified. Refer to Chapter 5 for parameter settings.

Ramp The AC drive output frequency decelerates in the time specified by Pr.11
or Pr.13, down to the frequency specified by Pr.08, and then the drive output
turns off.
Coast The AC drive is turned off immediately while the motor free runs until it
comes to a complete stop.

This parameter determines the AC drive’s maximum output frequency. All the AC
drive analog inputs (0 - 10V, 4 - 20mA) are scaled to correspond to the output
frequency range. (See graph on Page 24)

d010.0 -d400.0 Hz
This value should be set according to rated frequency of the motor as indicated on
the motor nameplate (See graph on Page 24). Maximum voltage frequency
determines the volts per hertz ratio. For example, if the drive is rated for 460 VAC
output and the maximum voltage frequency is set to 60Hz, the drive will maintain a
constant ratio of 7.66 v/Hz.
