The EJ5152 EtherCAT plug-in module is an interface for connecting two 24 V DC incremental encoders (24 V HTL) with A and B tracks via the signal distribution board. Alternatively, the EJ5152 can be used as an up or down counter. The encoder can be supplied with 24 V directly via the supply on the signal distribution board.
Special features:
- parameterizable per channel
- counter function can be set via process data
- integrated frequency and period measurement
- can optionally be used as 24 V up/down counter
- microincrements
- synchronous reading of the position value via distributed clocks
In addition, the EJ5152 enables measurement of a period or frequency at a resolution of 100 ns. Thanks to the optional interpolating microincrements functionality, the EJ5152 can deliver even more precise axis positions for dynamic axes. Furthermore, it supports synchronous reading of the encoder value together with other input data in the EtherCAT system via the high-precision EtherCAT Distributed Clocks (DC). In addition, timestamps are available for the last registered incremental edge. The implementation of the encoder profile allows the process data to be linked to the motion control application quickly and easily.
