The EP5101-0011 EtherCAT Box is an interface for the direct connection of incremental encoders with differential signals (RS422) or TTL single ended signals. Input frequencies up to 1 MHz can be evaluated. Two additional 24 V digital inputs are available for storing, locking and setting the counter reading. The error message output of an encoder can be connected and evaluated via the status input. The 5 V supply of the encoder is directly provided via the D-sub socket of the EP5101-0011.

 

Special features:

  • save, lock, set counter
  • integrated frequency and period measurement
  • optionally usable as 5 V counter
  • microincrements
  • synchronous reading of the position value via distributed clocks
  • timestamp on the last-registered incremental edge

 

In addition, the EP5101-0011 enables the measurement of a period or frequency with a resolution of 100 ns. With the optional interpolating microincrement functionality, the EP5101-0011 can provide even more accurate axis positions for dynamic axes. It also supports synchronous reading of the encoder value together with other input data in the EtherCAT system via the high-precision EtherCAT distributed clocks (DC). A timestamp for the last-registered incremental edge is also available. The use of encoder profiles enables simple and fast linking of the process data for motion control applications.
