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:

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.2, 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

9 Check to make sure that the package includes an AC drive, the User Manual, dust covers and rubber bushings.

9 Inspect the unit to insure it was not damaged during shipment.

9 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:

9 Store in a clean, dry location.

9 Store within an ambient temperature range of -20°C to +60°C.

9 If possible, store in an air-conditioned environment where the relative humidity is less than 95%, non-condensing.

9 Do not store the AC drive in places where it could be exposed to corrosive gases. 9 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.

Installation Requirements

Install the AC drive vertically to provide proper ventilation. Adequate space is required between the drive and a wall or other equipment. The figure below shows the minimum space needed. All enclosures must provide adequate ventilation and the internal ambient temperature must be kept at 40°C or below.

(4)Attention:

9 The user must provide a circuit breaker or disconnect switch and fuses in accordance with all applicable electrical codes.

9 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.)

9 Use ground leads that comply with AWG standards. Make the length of these ground leads as short as possible.

9 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.

9 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.

9 When power is applied to the AC drive, the DC bus charge indicator LED will be on.

9 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.

9 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

9 To reverse the direction of rotation, interchange any two connections of the three motor leads.

9 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.

Control Circuit Wiring

(1) Control terminal block designations

The control leads must be routed separately from the power supply and motor leads. They must not be fed through the same cable conduit.
