Sensor hub for intelligent servo motors that “say” when maintenance is required
With the sHub® sensor hub, servo motors can be used as a source of data for condition monitoring and predictive maintenance of the machine. The data is collected in the motor and transmitted to the control using the HIPERFACE DSL®. Monitoring occurs in real time. It is therefore possible for the maintenance staff to react in a timely manner and intervene in machine processes, e.g. if servo motors are imbalanced. sHub provides additional sensor data such as vibration for intelligent servo drive systems, therefore increasing the efficiency and reliability of machines.

Sensor hub with a maximum of 2 inputs for external sensors
The sensor data is integrated in to the motion control system via HIPERFACE DSL®.
Collection of vibration, temperature, speed, position and service life histogram of the servo motor (combined with EDS/EDM35)
Condition monitoring for maximum machine availability
The sHub® can identify servo motor damage early on. The space-saving sensor hub extends the motor feedback system to include additional sensors for measuring vibration and temperature. The two measurands deliver decisive data for the detection of early damage. For example, when a ball bearing is defective or the servo motor is unbalanced. The synchronous detection of position and vibration data by the sHub® increases the forecast accuracy of when a component will fail. With these findings, the machine availability can be maximized with predictive maintenance and unplanned downtime can be effectively prevented.
Additional vibration and temperature data of the sHub® enables high-precision access monitoring – and increases the availability of servo motors
Higher reliability thanks to optimal performance
Combined with the EDS/EDM35 motor feedback system, the sHub® creates an ideal foundation for condition monitoring. The EDS/EDM35 fulfill even the highest performance standards with the newly-developed optical scanning system including dual-channel scanning as well as shock and vibration resistance. Since the motor feedback system enables drive safety functions such as safely-limited speed (SLS), it is the first choice for high-precision and safety-related servo drives. And thanks to the reliable singleturn absolute position, a reference drive is not even necessary.
The sHub® and EDS/EDM35 make a powerful team; they ensure the integration of relevant safety functions and therefore high-precision and safe servo drives
Powerful and very safe communications thanks to the HIPERFACE DSL®
Data is transmitted into the drive system by the sHub® using the purely digital HIPERFACE DSL® motor feedback protocol. The system consisting of the sHub® and EDS/EDM35 is well-suited for integration into safety applications thanks to the safe communication interface. Even safe motion applications can be easily solved in this way. Only one cable is needed for the entire communication. This reduces connection costs and energy consumption as well as the amount of cables needed on-site, and also creates a better overview with lower space requirements.
With the digital HIPERFACE DSL® communication interface, status monitoring of servo motors can be done in real time – with the highest level of safety
