CHINT NVF5 Series Instruction Manual page 2

Thank you for choosing CHINT NVF5 series inverter.
Featuring fast load response, large low frequency torque and high overload capacity, the NVF5
series inverter adopts speed sensorless vector control technology to achieve precise control of various
equipment. With its constant voltage output, torque limitation, rotational speed tracking, simplified
PLC and process PID functions, this product is designed to meet the electrical driving demands of
various applications including wiredrawing, textile, machine tool, papermaking, packaging, food,
plastic, fans and pumps, and all kinds of automatic production equipment.
NVF5 series inverter is equipped with multiple communication functions such as standard RS485
communication protocol, scalable Ethernet, Profibus-DP, Devicenet and CANopen. It is also equipped
with multiple scalable I/O ports to meet the demands for complex onsite operation and system
integration.
Fully taking into account the harmonic interference from power grid as well as the dust and oil
pollutions that may occur to the product, the NVF5 series inverter is equipped with internal anti-
harmonic interference circuit which can suppress harmonic interference efficiently. Its modular
structure can prevent dust and oil from entering inside the machine. For NVF5-7.5/TS4-B series and
below, user can add an optional dust guard to achieve IP22 protection so the product can be used
under various complex conditions.
NVF5 series inverter offers three menu modes (Simple, Customized and Engineering) to meet the
needs of different users. The Simple mode offers simple operations which are easy to learn and use,
this mode is applicable to beginners. The Customized mode offers customizable menu options which
are applicable to dedicated equipment commissioning personnel. The Engineering mode includes all
functional parameters which is applicable to professional inverter commissioning personnel.
