INVT High-Performance AC Drive (Variable Frequency Drive - VFD)

Product Overview

Unlock the full potential of your electric motors and machinery with INVT High-Performance AC Drives. As a global leader in industrial automation, INVT delivers cutting-edge Variable Frequency Drives (VFDs) designed to provide precise control, optimize energy consumption, and enhance the reliability of a vast array of industrial applications.

INVT AC Drives are sophisticated motor control devices that adjust the frequency and voltage of the power supplied to an AC induction motor, thereby controlling its speed and torque. Whether you need to regulate flow in pumps and fans, achieve pinpoint accuracy in manufacturing processes, or boost efficiency across your entire operation, INVT provides a robust, intelligent, and cost-effective solution.

Key Features

INVT AC Drives are engineered with advanced technology and user-centric design, offering a comprehensive suite of features:

• Advanced Control Modes:
  • V/F Control: For general-purpose applications like fans and pumps.
  • Sensorless Vector Control (SVC): Provides excellent speed regulation and high torque at low speeds without the need for an encoder.
  • Closed-Loop Vector Control (FVC): Delivers superior speed accuracy, dynamic response, and full torque at zero speed, ideal for demanding applications requiring precise position or speed control.
• Wide Power Range: Available from fractional horsepower (0.4 kW) to high-power industrial solutions (up to 1200 kW), catering to diverse application requirements.
• Voltage Compatibility: Supports various input voltages including single-phase 220V, three-phase 220V, 380V, 480V, and 690V.
• Robust Protection Functions: Comprehensive motor and drive protection against overcurrent, overvoltage, undervoltage, overload, overheating, short circuit, ground fault, phase loss, and more, ensuring maximum operational safety and extended equipment life.
• Integrated Communication Protocols: Standard built-in Modbus RTU for seamless integration into existing control systems. Optional support for Profibus-DP, PROFINET, EtherCAT, CANopen, and DeviceNet is available on various series.
• Flexible I/O Options: Multiple configurable digital inputs/outputs, analog inputs/outputs, and relay outputs for versatile system interfacing.
• Built-in PLC Functionality: Many INVT series feature an integrated PLC, allowing for simplified local control logic programming and reducing the need for external PLCs in certain applications.
• User-Friendly Interface: Intuitive LED or LCD keypads with multi-language support, quick setup wizards, and easy parameter navigation for straightforward programming and monitoring. PC-based software tools also available for advanced configuration and diagnostics.
• Compact and Modular Design: Space-saving designs facilitate easier installation in control cabinets, while modular components allow for simpler maintenance and upgrades.
• High Overload Capacity: Capable of handling temporary overloads (e.g., 150% for 60 seconds, 180% for 10 seconds) to manage sudden load changes effectively.
• Harmonic Mitigation: Features such as built-in DC reactors (on certain models) and advanced control algorithms help reduce harmonic distortion, improving power quality and minimizing interference with other equipment.
• Flexible Braking Options: Supports dynamic braking via external braking resistors and DC braking for rapid deceleration or holding applications.
• Motor Auto-tuning: Automatically measures motor parameters for optimal drive performance and control.
• Multi-speed and PID Control: Supports up to 16 preset speeds and built-in PID functionality for closed-loop process control (e.g., pressure, temperature, flow).

Benefits of Choosing INVT AC Drives

Investing in INVT AC Drives brings significant advantages to your industrial operations:

• Exceptional Energy Savings: Precisely matches motor speed to load requirements, dramatically reducing energy consumption compared to fixed-speed operation. This leads to substantial cost reductions and a quick return on investment.
• Enhanced Process Control & Accuracy: Achieves precise speed, torque, and position control, resulting in higher product quality, reduced waste, and optimized process efficiency.
• Extended Equipment Lifespan: Gentle starting and stopping (soft start/stop) eliminates mechanical shock and stress on motors, gearboxes, belts, and other machinery components, prolonging their operational life and reducing wear and tear.
• Reduced Maintenance Costs: Less mechanical stress on equipment translates to fewer breakdowns, reduced need for spare parts, and lower labor costs associated with repairs.
• Increased Productivity: Optimized machine operation, faster cycle times, and consistent performance contribute directly to higher output and overall productivity.
• Seamless Integration: Industry-standard communication protocols and flexible I/O ensure easy integration into existing or new automation systems.
• Improved Power Factor: Drives inherently improve the system's power factor, reducing utility penalties.
• Reliability & Durability: Built with high-quality components and rigorous testing, INVT drives are designed for continuous, reliable operation in harsh industrial environments.
