The ECI 123 Splus inductive encoder with integrated vibration analysis
An integrated acceleration sensor in the new ECI 123 Splus inductive rotary encoder from HEIDENHAIN enables position measurement and vibration analysis with just one device. This significantly simplifies condition monitoring and maintenance planning for highly loaded automation systems.
In high-performance automation systems in particular, it is crucial for undisturbed production processes, perfect manufacturing results and long-lasting machine use to detect vibrations at an early stage. This makes it all the quicker and easier to avoid damaged products, machine damage or system failures. A new and particularly convenient solution for detecting and analyzing vibrations on rotating machine elements is the new ECI 123 Splus inductive rotary encoder from HEIDENHAIN with integrated acceleration sensor.
The ECI 123 Splus performs position measurement and vibration analysis and thus drive control and condition monitoring of rotating machine elements in a single device. It links the recorded vibration signals with the position values, thus also providing information that allows quick conclusions to be drawn about the type and position of a vibration source. In addition, up to three external temperature sensors can be connected to the new encoder. The ECI 123 Splus transmits all this information to the downstream control electronics via the EnDat 3 interface. On the one hand, this saves additional sensors for vibration measurement and, on the other, significantly reduces the cabling and installation effort.
For vibration measurement on rotary axes, the ECI 123 Splus has an integrated 3-axis acceleration sensor including a microcontroller for evaluating the data. This enables an initial order analysis with output of up to 64 orders directly in the encoder. For further analyses, the ECI 123 Splus transmits the data purely serially to the downstream control system via the EnDat 3 interface. Here, the system manufacturer can configure individual vibration analyses and, for example, define times for the analysis as well as the type of analysis and specify measuring axes, speed ranges or triggers. He can then monitor this data over time for changes in the orders relevant to him.
In this way, the ECI 123 Splus supports the customized online condition monitoring of a machine in order to detect faults at an early stage and analyze them precisely. Using this data, the plant operator can optimize the regular service intervals as part of predictive maintenance - adapted to the actual machine load - or integrate unscheduled maintenance into his operating processes in good time before a failure and downtime occurs. In addition, the data collected over the service life of the system also allows well-founded forecasts of the remaining useful life.
