INVT GD270-7R5-4 High-Performance Vector Drive Precision Torque Regulation

The INVT GD270-7R5-4 is a 7.5kW high-performance vector control variable frequency drive from INVT’s Goodrive270 series, designed for demanding industrial applications requiring precise torque, speed and position regulation. Featuring advanced open-loop and closed-loop vector control with encoder feedback support, built-in braking unit and comprehensive PLC functionality, this drive delivers exceptional dynamic response and torque accuracy across the full speed range. It is ideally suited for high-precision machine tools, winding and tension control systems, crane and hoist applications, injection molding machines, wire drawing equipment, printing and packaging lines, and elevator drive retrofits where superior torque regulation at low speeds, rapid dynamic response and reliable continuous operation are critical production and safety requirements.

• High-Performance Vector Drive — Advanced open-loop and closed-loop vector control algorithms deliver 200% starting torque at 0.5Hz (SVC) and 250% at 0Hz (FVC), ensuring robust performance across demanding speed and load ranges.
• Precision Torque Regulation — Torque control mode with ±3% accuracy in open-loop and ±0.5% in closed-loop enables precise tension control for winding, unwinding and web processing applications without external tension controllers.
• Built-in PLC Functionality — Integrated programmable logic with multi-function digital I/O, analog channels, relay outputs and timer/counter blocks eliminates the need for auxiliary PLCs in many standalone machine control applications.
• Rapid Dynamic Response — High-speed current and speed loop with advanced auto-tuning achieves sub-5ms torque response, making it ideal for high-acceleration machine tools, flying shears and fast positioning applications.
• Comprehensive Motor Adaptability — Supports asynchronous, synchronous PM and synchronous reluctance motors with automatic parameter identification, enabling maximum flexibility across diverse machine designs without drive replacement.
• Enhanced Protection & Reliability — Independent air duct design, heavy-duty IGBT module, phase loss protection and auto voltage regulation ensure continuous operation in harsh industrial environments with minimal downtime.
