The UNI1405 is designed to be adaptable to a variety of application scenarios. With its multiple operating modes, it caters to different system requirements. For straightforward applications, the Open Loop mode suffices. For applications demanding precise speed or torque control, the closed-loop vector mode can be employed. The Servo mode offers benefits for systems requiring positional accuracy, while the Regen mode is optimal for applications demanding energy feedback into the power supply.

The drive also stands out with its ability to deliver consistent output current across a range of frequencies, even at different ambient temperatures. This consistency ensures reliable operation and minimizes potential system downtimes.


Q: What is the primary use of the UNI1405 AC Drive?

A: The UNI1405 AC Drive by Control Techniques is designed for various applications requiring motor speed or torque control, including manufacturing processes, conveyors, and other machinery operations.

Q: Can the UNI1405 operate efficiently in high-temperature environments?

A: Yes, the UNI1405 provides consistent output currents across various frequencies even at an ambient temperature of 50°C. However, it's essential to note that the output current values differ between 40°C and 50°C.

Q: What safety measures should be taken during the installation of the UNI1405?

A: Always ensure that the drive is powered down during installation, adhere to the manufacturer's guidelines, and ensure proper grounding. If uncertain, seek assistance from a qualified technician.

Q: How does the Regen mode function?

A: The Regen (Regenerative) mode allows the drive to feed energy back into the power supply during operations like deceleration, making the system energy efficient.

Q: Is there any need for external cooling mechanisms for the UNI1405?

A: Depending on the application and environment, external cooling might be required, especially in conditions where the ambient temperature regularly exceeds 40°C.

In conclusion, the Control Techniques UNI1405 is a versatile and reliable AC Drive, tailored to meet diverse industrial requirements. Its array of operating modes, combined with its consistent performance metrics, makes it an excellent choice for professionals seeking efficiency and reliability.
