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).

1.5 Storage
The AC motor drive should be kept in the shipping carton or crate before installation. In order to retain
the warranty coverage, the AC motor drive should be stored properly when it is not to be used for an
extended period of time. Storage conditions are:
Store in a clean and dry location free from direct sunlight or corrosive fumes.
Store within an ambient temperature range of -20 °C to +60 °C.
Store within a relative humidity range of 0% to 90% and non-condensing environment.
Store within an air pressure range of 86 kPA to 106kPA.
CAUTION!
1. DO NOT store in an area with rapid changes in temperature. It may cause condensation and frost.
2. DO NOT place on the ground directly. It should be stored properly. Moreover, if the surrounding
environment is humid, you should put exsiccator in the package.
3. If the AC motor drive is stored for more than 3 months, the temperature should not be higher than 30 °C.
Storage longer than one year is not recommended, it could result in the degradation of the electrolytic
capacitors.

4. When the AC motor drive is not used for longer time after installation on building sites or places with
humidity and dust, it’s best to move the AC motor drive to an environment as stated above.

Chapter 2 Installation and Wiring
2.1 Ambient Conditions
Install the AC motor drive in an environment with the following conditions:
Operation Air Temperature: -10 ~ +40°C (14 ~ 104°F) for UL & cUL
-10 ~ +50°C (14 ~ 122°F) without dust cover.
Relative Humidity: <90%, no condensation allowed
Atmosphere pressure: 86 ~ 106 kPa
Installation Site Altitude: <1000m
Vibration: <20Hz: 9.80 m/s2(1G) max
20 ~ 50H: 5.88 m/s2(0.6G) max
Storage
Transportation
Temperature: -20°C ~ +60°C (-4°F ~ 140°F)
Relative Humidity: <90%, no condensation allowed
Atmosphere pressure: 86 ~ 106 kPa
Vibration: <20Hz: 9.80 m/s2(1G) max
20 ~ 50Hz: 5.88 m/s2(0.6G) max
Pollution Degree 2: good for a factory type environment.
CAUTION!
1. Operating, storing or transporting the AC motor drive outside these conditions may cause damage to the
AC motor drive.
2. Failure to observe these precautions may void the warranty!
2.2 Installation
1. Mount the AC motor drive vertically on a flat vertical surface object by screws. Other directions are not
allowed.
2. The AC motor drive will generate heat during operation. Allow sufficient space around the unit for heat
dissipation.
3. The heat sink temperature may rise to 90°C when running. The material on which the AC motor drive is
mounted must be noncombustible and be able to withstand this high temperature.
4. When AC motor drive is installed in a confined space (e.g. cabinet), the surrounding temperature must be
within 10 ~ 40°C with good ventilation. DO NOT install the AC motor drive in a space with bad ventilation.

Chapter 2 Installation and Wiring_VFD-B Series
2-2 Revision 10/2005, BE13, SW V4.08
5. When installing multiple AC more drives in the same cabinet, they should be adjacent in a row with
enough space in-between. When installing one AC motor drive below another one, use a metal
separation between the AC motor drives to prevent mutual heating.
6. Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the heatsink.
