Delta VFD-B Series User manual

Preface
Thank you for choosing DELTA’s high-performance VFD-B Series. The VFD-B 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-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 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).
