Absolute Encoder MEM-Bus EtherCAT

Elap absolute encoders series MEM-Bus comply with the Encoder Profile Specifications V4.1 version 3.162 related to Profidrives. They fulfil the requirements of the Application Classes 3 and 4,that is they provide all functions for scaling factor, preset, rotational direction, positioning and speed values, diagnostic. MEM-Bus encoders support the RT Real Time and IRT Isochronous Real Time transmission mode, thus ensuring fast, accurate and safe data transfer. Besides standard telegrams 81, 82, 83, 84 Elap encoders support the user telegram 860, featuring Profibus telegram, a peculiarity which simplifies the encoder handling, as well as the possible migration from Profinet devices. MEM-Bus encoders are supplied in multiturn version with 29 bit resolution (8192 steps/revolution x 65536 revolutions). Different mechanical versions are available to satisfy all application requirements: square flanged, round flanged, with solid or hollow shaft.

The absolute encoders series MEM-Bus avail on an interface to connect to field bus systems according to the CANopen standard. The encoders comply with standards CIA DS301, DS406, DS 305, featuring the functions of Class 2. They are supplied in multiturn version with 29 bit resolution (8192 steps/revolution x 65536 revolutions). The encoder operating parameters are set directly by the user: revolutions no., steps per rev., rotation direction and preset no. The diagnostic function signals possible parameter, position or temperature errors as well as the battery alarm – the data memory is anyway ensured for a long period (30 years). The baud rate and node selection can be easily set by LSS protocol or by means of dip-switches. MEM40-Bus encoders avail on 3 signalling LEDs for supply state, line and error. The encoder comes with metal housing, round flange, solid or hollow shaft. The electrical connection is by M12 connector. The encoders are UL listed for Canada and USA markets.

Elap encoders MEM-Bus EtherNet/IP can be easily integrated in any EtherNet/IP net, as they comply with all EtherNet/IP interface requirements, according to directives IEC61784-1. The encoder features the encoder profile 22H according to CIP™ protocol specifications.The encoders are ODVA conformant certified, including CIP Sync certification.MEM-Bus encoders are supplied in multiturn version with 29 bit resolution (8192 steps/revolution x 65536 revolutions). Different mechanical versions are available to satisfy all application requirements: square flanged, round flanged with servo coupling, and with hollow shaft to couple directly to a motor shaft; all the types offer different options for the shaft/hole diameter. The electrical connection is by 3 M12 connectors. The stout aluminium case ensures a high protection degree, so that it is possible to apply MEM-Bus encoders in severe industrial environments. MEM-Bus EtherNet/IP are UL certified for the Canadian and United States market.

Wire transducers series WPS are composed by the draw-wire mechanics coupled to Elap multiturn absolute high-resolution encoder MEM-BUS or MEM. They can provide different communication protocols – EtherNet/IP, EtherCAT, PROFINET, Profibus, CANopen or SSI output signal. The encoder grants high resolutions values (28 or 29 bit) and two availble strokes: 2300 or 5000 mm. The housing is out of glass fiber reinforced nylon, whilst the wire consists of coated poliamide stainless steel.
