ej5151

The EJ5151 EtherCAT plug-in module is an interface for connecting a 24 V incremental encoder (24 V HTL) via the signal distribution board. An additional 24 V digital input is available for storing or blocking the counter reading. Alternatively, the EJ5151 can be used as up/down counter. The 24 V supply of the encoder can be provided directly via the supply on the signal distribution board.   Special features: save, lock, set counter integrated frequency and period measurement opptionally usable as 24 V up/down counter microincrements synchronous reading of the position value via distributed clocks timestamp on the last-registered incremental edge   In addition, the EJ5151 enables the measurement of a period or frequency with a resolution of 100 ns. With the optional interpolating microincrement functionality, the EJ5151 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.
