Preface

Thank you for choosing DELTA’s high-performance VFD-S Series. The VFD-S Series is

manufactured with high-quality components and materials and incorporate 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-S 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-S 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-S series is used only to control variable speed of 3-phase induction motors, NOT for 1-

phase motors or other purpose.

7. VFD-S series shall NOT be used for life support equipment or any life safety situation.

WARNI NG!

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 personnel are allowed to install, wire and maintain AC motor drive.

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 for 230V models (≤ 120V for 115V models, ≤ 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.

General Wiring Information



Applicable Codes

All VFD-S 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

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

compliance with U.L. standards is a required.

2-16 Revision August 2008, SE09, SW V2.61

Chapter 2 Installation and Wiring|VFD-S Series

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. Pins

1 & 2 are the power supply for the optional copy keypad only and should not be used for RS-485

Magnetic contactor (Optional)

Please do not use a Magnetic contactor as the I/O switch of the AC motor drive, as it will reduce the operating life cycle of the AC drive.

Used to improve the input power factor, to reduce harmonics and provide protection from AC line

disturbances (surges, switching Input AC Line Reactor (Optional)

spikes, short interruptions, etc.). AC

line reactor should be installed when

the power supply capacity is 500kVA

or more and or advanced capacity is

activated. And the mains wiring

distance should be

10m. Refer to

Appendix B for details.

Zero phase reactors are used to

Zero-phase Reactor (Ferrite Core Common Choke) (Optional)

reduce radio noise especially when

audio equipment is installed near the

inverter. Effective for noise reduction

on both the input and output sides.

Attenuation quality is good for a wide

range from AM band to 10MHz.

General

Keep control wiring as far 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 general GFCI (Ground Fault Circuit Interrupter), select a current sensor



with sensitivity of 200mA or above, 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

 Pr.1-10. This parameter is used to determine the time required for the AC drive to decelerate

from the Maximum Output Frequency (Pr.1-00) down to 0 Hz. The rate is linear unless S-

Curve is “Enabled.”

 The acceleration/deceleration time 2 determines the time for the AC drive to

acceleration/deceleration from 0Hz to Maximum Output Frequency (Pr.1-00)

(acceleration/deceleration time 1 is the default). A Multi-Function Input terminal must be

programmed to select acceleration/deceleration time 2 and the terminals must be closed to

select acceleration/deceleration time 2. See Pr.4-04 to Pr.4-8-

 In the diagram shown below, the acceleration/deceleration time of the AC drive is the time

between 0 Hz to Maximum Output Frequency (Pr.1-00). Suppose the Maximum Output

Frequency is 60 Hz, start-up frequency (Pr.1-05) is 1.0 Hz, and acceleration/deceleration time

is 10 seconds. The actual time for the AC drive to accelerate from start-up to 60 Hz is 9.83

2-02 Stop Method

Factory Setting: d0

Settings d0 STOP: ramp to stop E.F.: coast to stop

d1 STOP: coast to stop E.F.: coast to stop

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

valid stop command or detects External Fault.

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

the deceleration time set in Pr.1-10 or Pr.1-12 and then stops.

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

runs until it comes to a complete standstill.

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 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.

 The analog output voltage is directly proportional to the output frequency of the AC drive. With

the factory setting of 100%, the Maximum Output Frequency (Pr.1-00) of the AC drive

corresponds to +10VDC analog voltage output. (The actual voltage is about +10VDC, and

can be adjusted by Pr.3-01).

 The analog output voltage is directly proportional to the output current of the AC drive. With

 The voltage output type of the output signal at terinals AFM is PWM, so this analog voltage is

only suitable to connect an external movable coil meter, not suitable to connect a digital meter

or for A/D signal conversion.

NOTE

Voltmeter specification: The sourcing capability of the output is limited to 0.21mA. Sourcing voltage:

10V. Output resistance: 47kΩ.

If the meter reads full scale at a voltage less than 10 volts, then Pr.3-01 should be set by the

following formula: Pr.3-01 = ((meter full scale voltage)/10) ×100%

Revision August 2008, SE09, SW V2.61 5-31

Chapter 5 Parameters|VFD-S Series

For example: When using the meter with full scale of 5 volts, adjust Pr.3-01 to 50%.

 The parameter determines the upper limit value of the internal counter. The internal counter

can be triggered by the external terminal (Pr.4-4 to Pr.4-8, d19). Upon completion of counting,

the specified output terminal will be activated. (Pr.3-05, Pr.3-06, d14).

3-04 Preliminary Count Value Unit: 1

Settings d0 to d999 Factory Setting: d0

 When the counter value is counted up from “1” to the setting value of this parameter, the

corresponding multi-function output terminal which set to d15 as Preliminary Counter Value

Attained will be closed. The application can be that closing the multi-function output terminal

makes the AC drive operate at low speed until stop before the counting value is going to be

attained.

 Pr.4-00 to Pr.4-03 are used when the source of frequency command is the analog signal (0 to

+10V DC or 4 to 20 mA DC). Refer to the following examples.

Example 1:

The following is the most common method. Set parameter 2-00 to d1 (0 to +10V signal) or d2 (4 to

20mA current signal).

Example 2:

In this example with the potentiometer set to 0V the Output Frequency is 10 Hz. The mid-point of

the potentiometer becomes 40 Hz. Once the Maximum Output Frequency is reached any further

increase of the potentiometer will not increase output frequency.

Revision August 2008, SE09, SW V2.61 5-35

Chapter 5 Parameters|VFD-S Series

Example 3:

The example also shows the popular method. The whole scale of the potentiometer can be used as

desired. In addition to signals of 0 to 10V and4 to 20mA, the popular voltage signals also include

signals of 0 to 5V, 20 to 4mA or that under 10V. Regarding the setting, please refer to the following

examples.

Example 4:

This example shows a potentiometer range of 0 to 5 Volts.

Example 5:

In this example a 1 volt negative bias is used. In a noise environment, it is advantageous to use

negative bias to provide a noise margin (1V in this example).

generate a large signal such as 20 mA or 10V. With anti-slope enable, the large signal will slow or

stop the AC drive.
