Beckhoff Automation ej5101

The EJ5101 EtherCAT plug-in module is an interface for the direct connection of incremental encoders with differential signals (RS422) or TTL single ended signals via the signal distribution board. Two additional 24?V digital inputs are available for storing, blocking and setting the counter status. The error message output of an encoder can be connected and evaluated via the status input of the module. The encoder can be supplied with 5?V?DC directly from the EtherCAT plug-in module. ? Special features: save, lock, set counter integrated frequency and period measurement optionally usable as 5?V up/down counter microincrements synchronous reading of the position value via distributed clocks timestamp on the last-registered incremental edge ? In addition, the EJ5101 enables the measurement of a period or frequency with a resolution of 100?ns. With the optional interpolating microincrement functionality, the EJ5101 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 implementation of the encoder profile enables simple and fast linking of the process data for motion control applications.
