This drive is designed to operate efficiently under varying conditions, ensuring consistent performance across different operational modes. One of the standout features of the UNI2401 is its ability to handle multiple operating modes, including Open Loop, Closed Loop vector, Servo, and Regen. This versatility enables the drive to be used in various applications, from simple motor speed control to more complex servo and regenerative braking systems.

The drive can deliver a maximum continuous output current of 12 amps at a 40°C ambient temperature across various switching frequencies—3kHz, 4.5kHz, 6kHz, and 9kHz. At the highest frequency of 12kHz, the drive maintains a continuous output current of 11.7 amps, demonstrating its capacity to perform efficiently even under demanding conditions. When operating at a higher ambient temperature of 50°C, the drive maintains a continuous output current of 12 amps up to 6kHz, with slight reductions at higher frequencies—11.6 amps at 9kHz and 9.7 amps at 12kHz. This performance consistency across different temperatures and frequencies ensures that the UNI2401 can meet the needs of various industrial environments without compromising on reliability or efficiency.

Operating Modes and Flexibility

The Control Techniques UNI2401 AC Drive is designed to support multiple operating modes, providing exceptional flexibility in motor control. In Open Loop mode, the drive offers straightforward motor speed control without needing feedback devices, making it ideal for applications where simplicity and cost-effectiveness are priorities. In Closed-loop vector mode, the drive delivers precise torque and speed control by utilizing feedback from encoders or resolvers, making it suitable for applications requiring high accuracy and responsiveness.

The Servo mode enhances the drive's ability to control position, speed, and torque exceptionally, making it ideal for robotics, CNC machinery, and other high-performance systems. The Regen mode allows the drive to capture and reuse energy that would otherwise be lost during braking, significantly improving energy efficiency and reducing operational costs. This feature is particularly beneficial in applications with frequent start-stop cycles or where energy conservation is a priority.
