MEM – BUS Profinet Encoder

Absolute Multiturn Encoder with Profinet Interface for fast, accurate, and safe data transfer


About the MEM – BUS Profinet Encoder

The 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, these 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.

The encoders real time diagnostic function ensures the device state constant monitoring.

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.

The innovative electronic construction technology – involving no mechanical gear –allows to reach high acceleration and speed values and grants the transducer long life.

MEM-Bus encoders are PROFINET certified and UL listed for the Canadian and United States market.
