EL5101 | Beckhoff EtherCAT Terminal

The EL5101 EtherCAT Terminal 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, blocking and setting the counter status. The error message output of an encoder can be connected and evaluated via the status input. The 5 V and 24 V supply of the encoder can be provided directly via the terminal connection points.Special features:save, lock, set counterintegrated frequency and period measurementoptionally usable as 5 V up/down countermicroincrementssynchronous reading of the position value via distributed clockstimestamp on the last-registered incremental edgeIn addition, the EL5101 enables the measurement of a period or frequency with a resolution of 100 ns. With the optional interpolating microincrement functionality, the EL5101 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.
