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 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 AC motor drive easily

damage 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 quality person is allowed to install, wire and maintain AC motor drive.

CAUTION!

1. Some parameters settings can 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 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 AC motor drive must be d240V (d480V for 460V models, d600V for 575V models)
and the mains supply current capacity must be d5000A RMS (d10000A RMS for the t40hp (30kW)

models).

After removing the front cover, check if the power and control terminals are clear. 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.

Revision 10/2005, BE13, SW V4.08

Chapter 2 Installation and Wiring_VFD-B Series

The "Line Fuse Specification" in Chapter 11, lists the recommended fuse part number for each B-

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

with U.L. standards is a required.

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 following items after finishing 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 is 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

telephone line to the RS-485 communication port or permanent damage may result. Terminals 1 & 2 are the

power supply for the optional copy keypad PU06 only and should not be used for RS-485 communication.

There may be an inrush current during
power up. Please check the chart of
Appendix B and select the correct fuse
with rated current. Use of an NFB is
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 spikes, short
interruptions, etc.). AC line reactor
should be installed when the power
supply capacity is 500kVA or more and
exceeds 6 times the inverter capacity,
or the mains wiring distance

10m.

Zero phase reactors are used to 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. Appendix B
specifies the zero phase reactor.
(RF220X00A)

To reduce electromagnetic interference,
please refer to Appendix B for more
details.

Used to reduce the deceleration time of
the motor. Please refer to the chart in
Appendix B for specific Braking
Resistors.

Motor surge voltage amplitude depends
on motor cable length. For applications
with long motor cable (>20m), it is
necessary to install a reactor at the
inverter output side.

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.

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 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.

DANGER!

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

with high voltage.

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.

Frequency will be limited to 50Hz.

If the Output Frequency Lower Limit is 10Hz, and the Minimum Output Frequency (Pr.01-05) is set to 1.0Hz,

then any Command Frequency between 1.0-10Hz will generate a 10Hz output from the drive.

This parameter must be equal to or less than the Output Frequency Upper Limit (Pr.01-07).

The Output Frequency Lower Limit value = (Pr.01-00 * Pr.01-08) /100.

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).

Both external terminal JOG and key “JOG” on the keypad can be used. When the Jog command is “ON”, the

AC motor drive will accelerate from Minimum Output Frequency (Pr.01-05) to Jog Frequency (Pr.01-14).

When the Jog command is “OFF”, the AC motor drive will decelerate from Jog Frequency to zero. The used

Accel/Decel time is set by the Jog Accel/Decel time (Pr.01-13, Pr.01-22).

Before using the JOG command, the drive must be stopped first. And during Jog operation, other operation

commands cannot be accepted, except command via the FORWARD, REVERSE and STOP keys on the

digital keypad.

aAuto-Acceleration / Deceleration

Factory Setting: 00

Settings 00 Linear acceleration / deceleration

01 Auto acceleration, linear Deceleration.

02 Linear acceleration, auto Deceleration.

03 Auto acceleration / deceleration (set by load)

04 Auto acceleration / deceleration (set by Accel/Decel Time setting)

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 braking resistor.

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

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).

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.

Chapter 5 Parameters_VFD-B Series

(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.
