Control Techniques UD53 Overview

UD 53 Resolver Interface Module: Enhancing Unidrive Control Units


The Control Techniques UD 53 resolver interface module stands as a compact yet crucial addition tailored for integration with the Unidrive control unit. Crafted in the United Kingdom, these modules cater to a spectrum of industries, including metal production, paper processing, and material conveying applications. Supported by a robust 2-year warranty from MRO Electric, these modules exemplify reliability in operation. Additionally, our inventory extends to encompass option modules from manufacturers such as Siemens and Yaskawa, ensuring a diverse array of solutions to meet varying needs.

Unidrive Applications

Designed specifically for the Unidrive, the UD 53 resolver interface module serves as an indispensable component for driving precision and efficiency in industrial settings. Boasting compatibility with resolvers, the UD 53 adheres to stringent specifications, including:

  • Input impedance exceeding 85Ω at 6kHz
  • Turns ratio configurations of either 3:1 or 2:1 for primary to secondary
  • Excitation voltage options of 6VRMS or 4VRMS

Operations for UD 53 Utilization

Operating at the forefront of position and speed feedback mechanisms, the UD 53 module assumes a pivotal role within the Unidrive ecosystem. When integrated into a drive unit, it functions exclusively within two distinct modes: closed-loop vector or closed-loop servo mode. These operational modes ensure precise control and feedback mechanisms, facilitating optimal performance in demanding industrial environments.

Simulator Encoder Outputs

The simulated encoder outputs generated by the UD 53 module yield Quadrature AB signals, intricately aligned with the line counts sourced from the encoder. Configurable for both frequency and direction, these outputs exhibit remarkable versatility, retaining vital positional information even amidst directional shifts. With the resolver serving as the default source for simulated encoder output, users can seamlessly leverage Encoder I, the primary encoder connected to the 15-way D-type on the drive, as an alternative source. Additionally, the module allows for convenient scaling of pulse counts per revolution by factors of 2, further enhancing adaptability and precision in feedback mechanisms.


Facilitating seamless integration, the UD 53 small option module finds its designated slot within the bay of the Unidrive, ensuring a snug fit and optimal performance. External equipment connections are facilitated through multiway connectors, streamlining the integration process. Leveraging a plugin 16-way screw terminal block on the UD 53 module, users can establish robust connections with external equipment, ensuring reliability and ease of installation.


Q: What industries can benefit from the Control Techniques UD 53 resolver interface module?

A: The UD 53 module caters to a wide range of industries including metal production, paper processing, and material conveying applications, offering enhanced precision and efficiency.

Q: What operational modes does the UD 53 module support?

A: The UD 53 module operates exclusively in closed-loop vector or closed-loop servo mode, ensuring precise control and feedback mechanisms in industrial environments.

Q: How are external equipment connections made with the UD 53 module?

A: External equipment connections are facilitated through multiway connectors and a plugin 16-way screw terminal block on the UD 53 module, ensuring robust and reliable integration.
