The PROFIBUS communication protocol is widely used in industrial networks: thanks to their PROFIBUS DP interface the new ELAP MEM-Bus encoders can be easily integrated in all systems managed by PLC controllers.
Besides eliminating hard wiring in the automation of production lines by utilizing a single-cable bus structure, MEM-Bus encoders offer useful functionalities, such as the diagnostic function, which signals possible errrors in the parametrization or in positioning, and the possibility to set the operating parameters: the revolutions number, the number of steps per revolution, the rotation direction and one preset. All the different configurations are managed by the system master.
MEM-Bus encoders can be supplied both in single- and in multiturn version, with high resolution values: 13 bit for the singleturn encoder, 29 bit for the multiturn type (8192 steps/revolution x 65536 revolutions).
Different mechanical versions are available to satisfy all application requirements: MEM520 – Ø.58 mm round flanged with servo coupling, MEM540 – Ø 58 round flanged with Ø 36 mm centering mask, MEM620 – 63.5X63.5 square flanged, and MEM410 -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 cables: two or three cable glands option is available.
The stout aluminium case ensures a high protection degree, so that it is possible to use MEM-Bus encoders in severe industrial environments.
The innovative electronic construction technology – involving no mechanical gear –allow to reach high acceleration and speed values and grants the transducer a long life.
