The CHINT NVF2G Series is a high-performance, open-loop vector control inverter designed for the precise speed and torque control of three-phase asynchronous motors. Engineered for versatility, this VFD range spans from 2.2kW up to 160kW (and above), making it the ideal choice for heavy-duty industrial applications where reliability and energy savings are paramount.
As a flagship product from CHINT, the NVF2G series combines a compact structural design with superior EMC performance. It features a high starting torque, excellent speed accuracy, and robust motor protection protocols. Whether you are managing industrial fans, heavy-duty conveyors, or precision pump systems, the NVF2G provides the intelligent control necessary to optimize your facility's power consumption.
Advanced Vector Control Algorithm: Delivers high torque even at low speeds (150% rated torque at 0.5Hz), ensuring smooth startups for heavy-load machinery.
Energy Efficiency & Optimization: Features a built-in energy-saving mode that automatically optimizes the V/F curve based on the load, significantly reducing power costs for centrifugal fans and pumps.
High Reliability & Protection: Comprehensive protection suite including overvoltage, undervoltage, overcurrent, overload, and phase loss detection. The PCBA is treated with a specialized conformal coating to resist dust and moisture.
Integrated Communication: Supports standard Modbus RTU via RS485 interface, allowing for seamless integration into PLC-controlled automated systems and Building Management Systems (BMS).
User-Friendly Interface: Equipped with a detachable digital keypad with a speed control potentiometer, allowing for easy parameter adjustment and real-time monitoring of frequency, current, and voltage.

Compact Footprint: The modular design allows for side-by-side installation in control cabinets, saving valuable space for panel builders.
Auto-Tuning Capabilities: Supports both static and dynamic motor parameter auto-tuning, allowing the VFD to match the motor's characteristics perfectly for maximum efficiency.
Reduced Harmonic Interference: Designed with built-in DC reactors (on higher power models) and optimized EMI filters to minimize interference with sensitive electronic equipment.
Q: What is the difference between "G Type" and "P Type" loads?
A: "G Type" is for General/Constant Torque loads (like conveyors or compressors) requiring higher overload capacity. "P Type" is for Fans/Pumps (Variable Torque) where high starting torque is less critical but energy efficiency is the priority.
Q: Can this VFD be used with a single-phase power supply?
A: The NVF2G series listed here is specifically for Three-Phase 380V input. For single-phase 220V requirements, please consult our NVF3 Series or specific 220V models.
Q: How do I set up the Modbus communication?
A: The NVF2G supports RS485. You can configure the baud rate, parity, and station address via parameters P0.01 and the PD communication parameter group in the manual.
