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.

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 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).



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.

Chapter 2 Installation and Wiring|VFD-B Series

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.



Terminals [+1, +2] for connecting DC reactor

To improve the power factor and reduce harmonics, connect a DC reactor between terminals



[+1, +2]. Please remove the jumper before connecting the DC reactor.

NOTE

Models of 15kW and above have a built-in DC reactor.

Terminals [+2/B1, B2] for connecting brake resistor and terminals [+1, +2/B1] for connecting

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

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.

Carefully check the following items before proceeding.

Make sure that the wiring is correct. In particular, check that the output terminals U, V, W.



are NOT connected to power and that the drive is well grounded.

Verify that there are no short-circuits between terminals and from terminals to ground or



mains power.

Check for loose terminals, connectors or screws.



Verify that no other equipment is connected to the AC motor



Make sure that all switches are OFF before applying power to ensure that the AC motor

NOTE

1. Stop running immediately if any fault occurs and refer to the troubleshooting guide for solving

the problem.

2. Do NOT touch output terminals U, V, W when power is still applied to L1/R, L2/S, L3/T even

when the AC motor drive has stopped. The DC-link capacitors may still be charged to

hazardous voltage levels, even if the power has been turned off.

3. To avoid damage to components, do not touch them or the circuit boards with metal objects or

your bare hands.

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).

 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,

Chapter 5 Parameters|VFD-B Series

 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.

 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).

 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.
