Control Techniques UNI1404

The Control Techniques UNI1404 is a robust and efficient AC servo drive. The UNI1404 is a member of the Unidrive series, which is widely recognized for its advanced features and adaptability to a range of servo motor systems. This servo drive is ideal for applications requiring precise control, high speed, and torque accuracy.

Technical Description:

The UNI1404 AC servo drive operates at a nominal rating of 2.2 kW or 3.0 hp, making it suitable for medium to heavy-duty industrial tasks. It supports an output current (continuous) of 5.6 A at switching frequencies of 3 kHz to 12 kHz at an ambient temperature of 40 °C. This current rating slightly decreases to 5.1 A at the same frequencies when the ambient temperature rises to 50 °C. The typical input current for the servo drive is 7.8 A, with an input current (continuous) of 8.3 A (maximum).

The UNI1404 AC servo drive is designed to handle high power dissipation, with a maximum total power dissipation of 130 W at 3 kHz and 150 W at 12 kHz. This power dissipation capacity ensures efficient operation even under demanding conditions.

Voltage and Frequency Specifications:

The AC servo drive is compatible with a nominal AC supply voltage of both 400 V and 480 V. It can support maximum permissible motor cable lengths of 200 meters (660 feet) at 400 V and 150 meters (490 feet) at 480 V. This drive is engineered to provide optimal performance and efficiency. It features advanced control algorithms that ensure smooth and precise motor control. The UNI1404 can operate efficiently across a wide range of frequencies, from 3 kHz to 12 kHz.

Standard Mounting Precautions:

Proper mounting and installation of the UNI1404 are essential to ensure its optimal performance and longevity. It is recommended to use line reactors to reduce the risk of damage due to disturbances in the supply network.

When used with certain AC supply conditions or in environments with high power factor correction equipment, a line reactor with 2 % reactance should be included between the AC supply and the drive.

For three-phase drives, three individual reactors or a single three-phase reactor should be used. This helps in mitigating the effects of disturbances and maintaining the stability of the drive.
