The FR-E720-1.5K is a robust and reliable variable frequency drive designed for general-purpose industrial motor control applications. This model supports 1.5kW output power and operates from a standard 3-phase 380-480V AC supply, making it ideal for pumps, fans, conveyors, and small machine tools. With its sensorless vector control algorithm, the drive delivers high starting torque and stable speed regulation even at low frequencies. The built-in RS-485 Modbus RTU interface simplifies integration into existing automation networks. Its compact footprint, combined with a user-friendly keypad and intuitive parameter navigation, allows for quick commissioning and maintenance. The FR-E720-1.5K is engineered for durability and includes multiple protection functions to ensure long-term operational safety in harsh industrial settings.
