Preface

Thank you for choosing DELTA’s high-performance VFD-S Series. VFD-S 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 motor drives. Keep this

operating manual handy and distribute to all users for reference.

WARNING

Always read this manual thoroughly before using VFD-S 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, do not remove the cover

of the AC drive until all “DISPLAY LED” lights on the digital keypad are off. Please note

that there are live components exposed within the AC drive. Do not touch these live parts.

CAUTION! Ground the VFD-S 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 (CH 3-1).

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,

V, and W directly to the AC main circuit power supply.

CAUTION! Heat sink may heat up over 70 (158), during the operation. Do not touch

the heat sink.
