The INVT GD270-1R5-4 is a specialized variable frequency drive from the Goodrive270 series, designed for three-phase 380V AC supply with a rated power of 1.5 kW. Engineered specifically for fan and pump applications, it offers energy-efficient control of three-phase asynchronous motors in HVAC systems, water treatment plants, and industrial circulation setups. This model integrates application-oriented features that simplify commissioning, enhance energy savings, and ensure reliable performance in demanding environments.
Design Philosophy: Optimized for Fluid and Air Control
The GD270-1R5-4 is built with a focus on application-specific intelligence for fluid and air movement systems. It includes dedicated PID controllers, multi-pump control logic, and an ECO energy-saving algorithm that dynamically optimizes motor operation based on real-time load demand, reducing energy consumption.
Key Features
Dedicated HVAC & Pump Functions: Pre-configured macros for constant pressure water supply, temperature control, and multi-pump automation, minimizing setup time.
ECO Energy-Saving Algorithm: Dynamically adjusts voltage and frequency to match motor load, significantly reducing power consumption in variable torque applications.
Enhanced Environmental Protection: Main control board features a thickened conformal coating for resistance against humidity, corrosive gases, and dust.
Flexible Communication Options: Supports multiple industrial protocols (e.g., Profibus-DP, Profinet, CANopen, Modbus-TCP) via optional plug-in cards for seamless integration into BMS or IoT platforms.
Anti-Blocking Function: Automatically reverses pump rotation to clear blockages, ideal for wastewater applications.

Frequently Asked Questions
What energy-saving benefits does this VFD offer for fans and pumps?
The drive leverages the affinity laws, where a small reduction in speed significantly lowers power consumption. Its ECO mode continuously optimizes voltage and flux levels based on real-time load, enhancing efficiency. Support for permanent magnet synchronous motors (PMSM) and features like sleep mode further reduce energy use.
How does the multi-pump control function work?
The built-in multi-pump logic automates the operation and alternation of up to four pumps. It adjusts pump operation based on system demand, eliminates the need for an external PLC, ensures even pump wear, and provides redundancy by activating standby pumps during failures.
Why is the conformal coating important?
The conformal coating protects the PCB from humidity, condensation, corrosive gases, and dust commonly found in pump rooms and industrial settings. This enhances reliability, reduces downtime, and extends the drive’s lifespan in harsh environments.
