Preface

Thank you for choosing DELTA’s high-performance VFD-B Series. The VFD-B 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-B 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. AC input power must be disconnected before any wiring to the AC motor drive is made.

2. 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.

3. Never reassemble internal components or wiring.

4. 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.

5. Ground the VFD-B 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.

6. VFD-B series is used only to control variable speed of 3-phase induction motors, NOT for 1-

phase motors or other purpose.

7. VFD-B 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 ≤ 240V (≤ 480V for 460V models, ≤ 600V for
575V models) and the mains supply current capacity must be ≤ 5000A RMS (≤10000A RMS for
the ≥ 40hp (30kW) models).

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.



General Wiring Information

Applicable Codes

All VFD-B series are Underwriters Laboratories, Inc. (UL) and Canadian Underwriters Laboratories

(cUL) listed, and therefore comply with the requirements of the National Electrical Code (NEC) and

the Canadian Electrical Code (CEC).

Installation intended to meet the UL and cUL requirements must follow the instructions provided in

“Wiring Notes” as a minimum standard. Follow all local codes that exceed UL and cUL

requirements. Refer to the technical data label affixed to the AC motor drive and the motor

nameplate for electrical data.

The "Line Fuse Specification" in Appendix B, lists the recommended fuse part number for each

VFD-B Series part number. These fuses (or equivalent) must be used on all installations where

compliance with U.L. standards is a required.

Chapter 2 Installation and Wiring|VFD-B Series

Revision July 2008, BE16, SW V4.08 & V5.00 2-13

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.

Mains power terminals (R/L1, S/L2, T/L3)



Connect these terminals (R/L1, S/L2, T/L3) via a no-fuse breaker or earth leakage breaker to

3-phase AC power (some models to 1-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.



DO NOT connect phase-compensation capacitors or surge absorbers at the output terminals

of AC motor drives.



With long motor cables, high capacitive switching current peaks can cause over-current, high

leakage current or lower current readout accuracy. To prevent this, the motor cable should

be less than 20m for 3.7kW models and below. And the cable should be less than 50m for

5.5kW models and above. For longer motor cables use an AC output reactor.



Use a well-insulated motor, suitable for inverter operation.



If the AC motor drive has a built-in brake chopper (all models of 11kW and below), connect

the external brake resistor to the terminals [＋2/B1, B2].



Models of 15kW and above don’t have a built-in brake chopper. Please connect an external

optional brake unit (VFDB-series) and brake resistor. Refer to VFDB series user manual for

details.



Connect the terminals [+(P), -(N)] of the brake unit to the AC motor drive terminals

[+2(+2/B1), (-)]. The length of wiring should be less than 5m with twisted cable.



When not used, please leave the terminals [+2/B1, -] open.

WARNING!

1. Short-circuiting [B2] or [-] to [+2/B1] can damage the AC motor drive.

Grounding terminals (

)



Make sure that the leads are connected correctly and the AC drive is properly grounded.

(Ground resistance should not exceed 0.1Ω.)



Use ground leads that comply with local regulations and keep them as short as possible.



Multiple VFD-B units can be installed in one location. All the units should be grounded

directly to a common ground terminal, as shown in the figure below. Ensure there are no

ground loops.

(common)

Common for AVI, ACI, AUI, AFM

Control signal wiring size: 18 AWG (0.75 mm2) with shielded wire.

Analog input terminals (AVI, ACI, AUI, ACM)



Analog input signals are easily affected by external noise. Use shielded wiring and keep it as

short as possible (<20m) with proper grounding. If the noise is inductive, connecting the

shield to terminal ACM can bring improvement.



If the analog input signals are affected by noise from the AC motor drive, please connect a

capacitor and ferrite core as indicated in the following diagrams:

Digital inputs (FWD, REV, JOG, EF, TRG, MI1~MI6, DCM)



When using contacts or switches to control the digital inputs, please use high quality

components to avoid contact bounce.

Digital outputs (MO1, MO2, MO3, MCM)



Make sure to connect the digital outputs to the right polarity, see wiring diagrams.



When connecting a relay to the digital outputs, connect a surge absorber or fly-back diode

across the coil and check the polarity.

Chapter 2 Installation and Wiring|VFD-B Series

Revision July 2008, BE16, SW V4.08 & V5.00 2-25

General



Keep control wiring as far away as possible from the power wiring and in separate conduits

to avoid interference. If necessary let them cross only at 90º angle.



The AC motor drive control wiring should be properly installed and not touch any live power

wiring or terminals.

NOTE



If a filter is required for reducing EMI (Electro Magnetic Interference), install it as close as

possible to AC drive. EMI can also be reduced by lowering the Carrier Frequency.



When using a GFCI (Ground Fault Circuit Interrupter), select a current sensor with sensitivity

of 200mA, and not less than 0.1-second detection time to avoid nuisance tripping. For the

specific GFCI of the AC motor drive, please select a current sensor with sensitivity of 30mA

or above.

DANGER!

Damaged insulation of wiring may cause personal injury or damage to circuits/equipment if it

comes in contact with high voltage.

Settings 0.01 to d 160.00 Factory Setting: 1.00

 The coefficient K determines the multiplying factor for the user-defined unit.

The display value is calculated as follows:

U (User-defined unit) = Frequency Command * K (Pr.00-05)

H (actual output) = Actual output frequency * K (Pr.00-05)

Example:

A conveyor belt runs at 13.6m/s at motor speed 60Hz.

K = 13.6/60 = 0.23 (0.226667 rounded to 2 decimals), therefore Pr.00-05=0.23

With Frequency command 35Hz, display shows LED U and 35*0.23=8.05m/s.

(To increase accuracy, use K=2.27 or K=22.67 and disregard decimal point.)

Maximum Output Frequency (Fmax) Unit: 0.01

Settings 50.00 to 400.00 Hz Factory Setting: 60.00

 This parameter determines the AC motor drive’s Maximum Output Frequency. All the AC

motor drive frequency command sources (analog inputs 0 to +10V, 4 to 20mA and -10V to

01 - 23 Accel/Decel Time Unit

Factory Setting: 01

Settings 00 Unit: 1 sec

01 Unit: 0.1 sec

02 Unit: 0.01 sec

 The Acceleration Time is used to determine the time required for the AC motor drive to ramp

from 0 Hz to Maximum Output Frequency (Pr.01-00). The rate is linear unless S-Curve is

“Enabled”, see Pr.01-16.

 The Deceleration Time is used to determine the time required for the AC motor drive to

decelerate from the Maximum Output Frequency (Pr.01-00) down to 0 Hz. The rate is linear

unless S-Curve is “Enabled.”, see Pr.01-17.

 The Acceleration/Deceleration Time 1, 2, 3, 4 are selected according to the Multi-Function

Input Terminals Settings. See Pr.04-04 to Pr.04-09 for more details.

 In the diagram shown below, the Acceleration/Deceleration Time of the AC motor drive is the

time between 0 Hz to Maximum Output Frequency (Pr.01-00). Suppose the Maximum Output

Frequency is 60 Hz, Minimum Output Frequency (Pr.01-05) is 1.0 Hz, and

Acceleration/Deceleration Time is 10 seconds. The actual time for the AC motor drive to

accelerate from start-up to 60 Hz and to decelerate from 60Hz to 1.0Hz is in this case 9.83

seconds. ((60-1) * 10 /60=9.83secs).

Chapter 5 Parameters|VFD-B Series

Revision July 2008, BE16, SW V4.08 & V5.00 5-33

 With Auto acceleration / deceleration it is possible to reduce vibration and shocks during

starting/stopping the load.

During Auto acceleration the torque is automatically measured and the drive will accelerate to

the set frequency with the fastest acceleration time and the smoothest start current.

During Auto deceleration, regenerative energy is measured and the motor is smoothly stopped

with the fastest deceleration time.

But when this parameter is set to 04, the actual accel/decel time will be equal to or more than

parameter Pr.01-09 ~Pr.01-12 and Pr.01-18 to Pr.01-21.

 Auto acceleration/deceleration makes the complicated processes of tuning unnecessary. It

makes operation efficient and saves energy by acceleration without stall and deceleration

without brake resistor.

 In applications with brake resistor or brake unit, Auto deceleration shall not be used.

01 - 16 Acceleration S-Curve

01 - 17 Deceleration S-Curve

Factory Setting: 00

Settings 00 S-curve disabled

01 to 07 S-curve enabled (07 is smoothest)

 This parameter is used to ensure smooth acceleration and deceleration via S-curve.

The S-curve is disabled when set to 00 and enabled when set to 01 to 07.

Setting 01 gives the quickest and setting 07 the longest and smoothest S-curve.

The AC motor drive will not follow the Accel/Decel Times in Pr.01-09 to Pr.01-12 and Pr.01-18

to Pr.01-21 when S-curve is enabled.

 The diagram below shows that the original setting of the Accel/Decel Time is only for reference

when the S-curve is enabled. The actual Accel/Decel Time depends on the selected S-curve

(01 to 07).

Factory Setting: 00

01 STOP: coast to stop E.F.: coast to stop

02 STOP: ramp to stop E.F.: ramp to stop

03 STOP: coast to stop E.F.: ramp to stop

 The parameter determines how the motor is stopped when the AC motor drive receives a valid

stop command or detects External Fault.

1. Ramp: the AC motor drive decelerates to Minimum Output Frequency (Pr.01-05)

according to the deceleration time and then stops.

2. Coast: the AC motor drive stops the output instantly upon command, and the motor

free runs until it comes to a complete standstill.

3. The motor stop method is usually determined by the characteristics of the motor load and

how frequently it is stopped.

(1) It is recommended to use “ramp to stop” for safety of personnel or to prevent

material from being wasted in applications where the motor has to stop after the

drive is stopped. The deceleration time has to be set accordingly.

(2) If the motor free running is allowed or the load inertia is large, it is

recommended to select “coast to stop”.

For example: blowers, punching machines, centrifuges and pumps.

Auxiliary Motor 1, 2 and 3

For the fan & pump control applications, one can use the

Multi-function Output Terminals (1-3) to define the auxiliary

motor. When using with group 10 PID Controls and group 11

Fan and Pump Control, it can control flow of many motors.

19

Heat Sink Overheat

Warning (OH1)

When the heatsink overheats, it will signal to prevent OH

from turning off the drive. When it is higher than 85

o

C

(185

o

F), it will be ON. If not, it will be OFF.

20 AC Motor Drive Ready Active when the drive is on and no abnormality detected.

21

Emergency Stop

Indication

Active once the drive’s emergency stop function is activated.

22

Desired Frequency

Attained 2

Active when the desired frequency (Pr.03-10) is attained.

23 Software Brake Signal

This function is used in conjunction with a VFDB Brake Unit.

The output will be activated when the drive needs help

braking the load. A smooth deceleration is achieved by using

this function.

24

Zero Speed Output

Signal

Active unless there is an output frequency present at

terminals U/T1, V/T2, and W/T3.

25 Under-current Detection

Active once the drive’s current has fallen below its minimum

allowable value. (Refer to Pr.06-12, 06-13)

26

Operation Indication

(H>=Fmin)

Active when there is output voltage from U, V, W.
