VFD-B Series

Preface

Thank you for choosing DELTA’s high-performance VFD-B Series. VFD-B Series are

manufactured by adopting high-quality components, material and incorporating the latest

microprocessor technology available.

 Getting Started

This manual will be helpful in the installation, parameter setting, troubleshooting, and daily

maintenance of the AC motor drives. To guarantee safe operation of the equipment, read

the following safety guidelines before connecting power to the AC drives. Keep this

operating manual handy and distribute to all users for reference.

WARNING

Always read this manual thoroughly before using VFD-B series AC Motor Drives.

DANGER!

AC input power must be disconnected before any maintenance. Do

not connect or disconnect wires and connectors while power is applied to the

circuit. Maintenance must be performed by qualified technicians.

CAUTION! There are highly sensitive MOS components on the printed circuit boards.

These components are especially sensitive to static electricity. To avoid damage to

these components, do not touch these components or the circuit boards with metal

objects or your bare hands.

DANGER! A charge may still remain in the DC-link capacitor with hazardous voltages

even if the power has been turned off. To avoid personal injury, please ensure that

power has turned off before operating AC drive and wait ten minutes for capacitors to

discharge to safe voltage levels.

CAUTION! Ground the VFD-B using the ground terminal. The grounding method

must comply with the laws of the country where the AC drive is to be installed. Refer to

Basic Wiring Diagram.

DANGER! The AC drive may be destroyed beyond repair if incorrect cables are

connected to the input/output terminals. Never connect the AC drive output terminals

U/T1, V/T2, and W/T3 directly to the AC main circuit power supply.

CAUTION! The final enclosures of the AC drive must comply with EN50178. (Live

parts shall be arranged in enclosures or located behind barriers that meet at least the

requirements of the Protective Type IP20. The top surface of the enclosures or barrier

that is easily accessible shall meet at least the requirements of the Protective Type

IP40). (VFD-B series corresponds with this regulation.)

CAUTION! Heat sink may heat up over 70

C (158

F), during the operation. Do not

touch the heat sink.
