LM10D01_04 Issue 4, 5 th July 2016 LM10 absolute magnetic encoder system Track system LM10 is an absolute magnetic linear encoder system which has been designed for motion control applications as a position and velocity control loop feedback element. The encoder system is highly reliable due to contactless absolute measuring principle, built-in safety algorithms and high quality materials/components used. The measuring standard is a magnetic scale which consists of a stainless steel substrate with an elasto-ferrite layer. The elasto-ferrite layer is magnetised with two tracks. The incremental track is magnetised with 2 mm long (alternating south and north) poles and the absolute track is magnetised with a pseudo random binary sequence (PRBS) absolute code with 1 bit length. The elasto-ferrite layer is immune to chemicals commonly found in industry. The readhead incorporates Hall sensor arrays for PRBS track reading, an MR sensor for incremental track reading, interpolation electronics and custom logic circuitry. The data from the Hall arrays and interpolator are processed in the logic circuitry using special algorithms to determine the absolute position. The electronic design provides extremely short response and recovery times, which consequently make it ideal for applications with highly dynamic control loops. Diagnostic information is available through a serial communication channel and status LED. If a failure is diagnosed, the encoder needs to be switched off and then switched on again in order to resume functionality. True absolute system Suitable for highly dynamic control loops Small footprint High accuracy Resolutions up to 0.244 µm xis lengths of up to 16. m Speeds up to 7 m/s at 0.977 µm resolution Integral status LED BiSS-C unidirectional communication protocol Simple and fast installation Robust measuring principle Excellent dirt immunity to IP68
