 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.

(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.

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

Troubleshooting and Fault Information

The AC drive has a comprehensive fault diagnosis system that includes more than 20 different alarms and fault messages. Once a fault is detected, the corresponding protective functions will be activated to turn off the AC drive output. The various AC drive failures may be classified as follows:

•

Over Voltage / Low Voltage

•

Heat sink Over Temperature

•

Motor Overload

•

AC drive Overload

•

Motor Stalled

•

Microprocessor Systems Failure

The three most recent faults are stored in the AC drive non-volatile memory and may be read through the digital keypad, or through the RS-485 interface on the control board.

Troubleshooting and Fault Information

This section provides information to guide the user in understanding the various AC drive fault conditions and their general troubleshooting procedures. A listing and description of the different AC drive failures is given, along with their possible solutions. A section on general troubleshooting is also included for reference.

Important: Pressing the Reset button will not restore the AC drive to its normal operating conditions unless the fault is corrected. During any failure, the AC drive switches off and an error message will appear in the display. The last error that occurred is stored in Pr.73.

All Braking Resistors & Braking Units Use in AC Drives

Note: Please only use DELTA resistors and recommended values. Other resistors and values will void Delta’s warranty. Please contact your nearest Delta representative for use of special resistors. For instance, in 460 V series, 100 HP, AC drive has 2 braking units with total of 16 braking resistors, so each braking unit uses 8 braking resistors. There should be at least 10 cm away from AC drive to avoid possible noise. Refer to the “Braking Unit Module User Manual” for further detail.
