The measurement is accomplished using a passive position marker which can be moved as a free-floating or guided element. Side coupling of the position marker reduces the installation envelope size, prevents the pump effect of slide arms and permits stroke lengths up to 4500 mm. The non-contact coupling version makes installation even simpler, and the wear-free operation means unlimited mechanical life expectancy and unlimited traverse speed of the position marker. The temperature coefficient of the transducer is extremely low thanks to the measuring principle, design and selected materials. The high mechanical ruggedness of the transducer combined with the underlying measuring technique mean that the system is highly resistant to shock and vibration. The active sensing element is encased in an aluminum housing rated to IP 67. This makes the transducer resistant to contamination, dust, moisture and oils. Mounting is accomplished using clamps that allow precise mechanical adjustment. A sophisticated ASIC in the transducer provides for standard absolute output signals. The CAN protocol of these transducers is compatible with CiA Standard DS-301 Rev. 4.02 and standard device profile DSP-406 Rev. 3.1 according to encoder class C1. The position and velocity of up to 2 position markers are transmitted on the bus using “Process Data Objects” (PDO’s). Additionally, according to standard freely programmable cams are available to signalize the passing of certain positions. Via CAN Interface the node- ID, baud rate, transmission mode, transmission cycle time, slope and travel direction and other parameters be largely varied. The parameters for configuration of the sensor are sent by the CAN controller in “Service Data Objects” (SDO’s). Node ID and data rate are varied either in Layer Setting Service (LSS; nach DSP 305 V1.1.2) or using SDO Object 0x2000. They are stored non-volatile memory. As a special feature, the sensor offers the Autobaud function: The Sensor is able to detect the bit rate of the network by “listening” to communication of existing members and to adjust his rate accordingly.
