ELAP new absolute encoders series MEM-Bus avail on an interface to connect to field bus systems according to the CANopen standard.
MEM-Bus encoders can be supplied both in single- and in multiturn version: the singleturn encoder resolution is 13 bit, while for the multiturn type the resolution value is 29 bit (8192 steps/revolution x 65536 revolutions).
The encoder operating parameters can be set directly by the user: revolutions no., steps per rev., rotation direction and preset no. The diagnostic function signals possible parameter and position errors as well as the battery alarm – the data memory is anyway assured for a long period (13 years). MEM-Bus encoders avail on 3 signalling LEDs for supply state, line and error.
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.
