Overview

The motor feedback systems have a communication interface and are designed for absolute multiturn integration. They have a 1,024 sine/cosine period per revolution and no safety system. motor feedback systems of the SRS/SRM50 product family are utilized worldwide across a diverse range of applications and environments. Boasting 1024 sine/cosine signals per revolution, this family stands as the pinnacle solution for motor feedback systems featuring the HIPERFACE interface. Leveraging a precise metal code disk and maximizing the distance between the two ball bearings, these systems ensure unparalleled accuracy.

They offer absolute location indication with an increment number of 32,768 increments per revolution and a maximum of 4,096 revolutions. Noteworthy features include the storage of motor-specific data in the electronic type label and programmability. Furthermore, these systems are certified to SIL2/PL d, meeting the latest safety technology requirements and streamlining the certification process.
