EL5101 - Incremental encoder interface - Beckhoff VietNam

























EL5101 Incremental encoder interface

The EL5101 EtherCAT Terminal is an interface for the direct connection of incremental encoders with differential inputs (RS422). A 3216 bit counter with a quadrature decoder and a 3216 bit latch for the zero pulse can be read, set or enabled. Incremental encoders with alarm outputs can be connected at the interface is status input. Interval measurement with a resolution of up to 100 ns is possible. The gate input allows the counter to be halted. The counter state is taken over with a rising edge at the latch input.
Due to the optional interpolating microincrement function, the EL5101 can supply even more precise axis positions for dynamic axes. In addition, it supports the synchronous reading of the encoder value together with other input data in the EtherCAT system via high-precision EtherCAT distributed clocks (DC).
