Techspan: HD2 High Performance AC Inverter Drives
February 26, 2025
High Performance, Torque Vector Inverters for AC Motors 1.5kw – 500KW (2HP – 670HP)
The HD2 range of inverters offer dynamic performance. Designed for controlling asynchronous AC induction motors and permanent magnet synchronous motors, the HD2 torque vector control range are packed full of features as standard that you would usually expect to find on higher specified inverters.
Utilizing advanced vector control technology, the HD2 range delivers sensor-less and closed loop vector control for both asynchronous and synchronous motors giving incredible speed response and control. HD2 offers reliability, environmental adaptability, high precision and stable performance – everything you have come to expect from an IMO inverter drive.
The HD2 also offers advantages to the customer including a huge range of functions with simple operation, industrial communication protocols (ModbusRTU, EtherCAT and Profinet) along with Bluetooth and WiFi communication for programming, and with more communication options in development.

Applications
Setting High Standards
The level of functionality offered by the HD2 range sets the bar high for efficiency, for example, the HD2 offers two sets of motor parameters which allow users to deploy one HD2 inverter to control different motors, which ultimately leads to increased savings.
High Performance at Low Speeds
The HD2 range offers torque vector control across the full range. IMO is well renowned for manufacturing industry reliable variable speed drives and the HD2, along with its sister HD1 inverter, innovate with feature rich inverter drives due to the vast array of standard features included that you would normally expect only to find in more expensive models.
The HD2 range delivers stable torque output even at low speeds thanks to its high-speed processor, allowing the HD2 to be used in an even wider range of applications including lifts, conveyor systems and high inertia loads that demand a higher starting torque and rapid controlled braking.
Enhanced Control Functionality
As you would expect, a drive from IMO produces solutions which tick every box, every time and the HD2 is no different. From offering motor auto-tune (both static and dynamic) which minimizes power losses, to PID control which allows motor operation whilst controlling temperature, pressure and flow rate without the use of an external device or controller, together with the inclusion of programmable logic functionality and encoder feedback capability, the HD2 is so packed with features that you would not believe they fit inside its compact and user-friendly form.
