A core strength of the GD20 is its dual-mode motor control. The drive supports V/F (voltage/frequency) control for simple, stable operation of standard loads, as well as sensorless vector control (SVC) for applications requiring stronger starting torque, tighter speed regulation and improved dynamic response. This flexibility allows users to match the control method to the application, ensuring smooth operation and accurate performance whether driving straightforward fan and pump duties or more demanding machine loads.

• The GD20 includes practical built-in functions that simplify machine design and operation.
• A built-in PID controller enables closed-loop control of process variables such as pressure, flow or temperature directly within the drive, often eliminating the need for an external controller in pump, fan and HVAC applications.
• Multi-step speed control allows preset speeds to be selected for sequenced operation, while a built-in brake unit on smaller ratings supports rapid, controlled stopping where required.
• These integrated capabilities reduce cost, save panel space and streamline application development.

Connectivity is provided through Modbus RS-485, allowing the GD20 to communicate with PLCs, HMIs and supervisory systems for parameter setting, monitoring and coordinated control. This native connectivity simplifies integration into larger control architectures and supports efficient, networked operation across the machine or plant. The GD20 integrates particularly well within an all-INVT automation system alongside INVT PLCs, HMIs and servo drives, enabling cohesive, single-brand solutions that streamline procurement, engineering and after-sales support.

The GD20 covers a wide power range from approximately 0.4 kW to 37 kW and is available in 1-phase 230 V and 3-phase 230/400 V configurations, allowing it to serve everything from small single-phase machines to substantial three-phase industrial loads. This breadth lets designers standardise on a single drive family across diverse applications, simplifying selection, spares and maintenance, while ensuring appropriate capacity and supply compatibility for each installation. The compact, reliable design eases panel layout and supports dependable operation in demanding environments.

Built to INVT's quality standards, the GD20 incorporates comprehensive protection functions that safeguard the drive and motor against conditions such as overcurrent, overvoltage, overtemperature and overload, contributing to dependable long-term operation. Its proven design and INVT's growing global presence provide accessible technical resources, documentation and supply continuity, giving users confidence in performance and support throughout the equipment's service life.

For buyers, the GD20 offers a dependable, energy-efficient drive at a competitive price, backed by INVT's integrated automation ecosystem. This enables organisations to build complete, coordinated machine solutions from a single trusted brand while controlling costs and benefiting from straightforward integration.
