Product Description:
The EL5101-1006 EtherCAT Terminal is a compact 1 channel interface for incremental encoders. It supports both RS422 differential and TTL single ended signal types. The terminal allows accurate position detection, frequency measurement and counter operations. It is suitable for motion control and automation systems requiring high speed signal acquisition up to 1 MHz.
The Beckhoff EL5101-1006 EtherCAT terminal includes connections for A, B and C channels with inverted signal support on RS422 (A̅, B̅, C̅). TTL signal types use A, B, and C without inversion. It offers 24 V digital inputs for functions like gate/latch and 5 V DC for status monitoring. The model provides a switchable 16/32 bit counter and a quadrature decoder with 4 fold evaluation. This allows for up to 4 million increments per second that is equivalent to a 1 MHz signal rate. The encoder is powered by a 5 V DC supply derived from the 24 V power contact and can draw up to 0.5 A. Distributed clocks in this model ensure synchronized data acquisition across the EtherCAT system. It enables synchronous position data capture that is important in coordinated motion tasks. A timestamp on the last incremental edge enhances precision. Nominal voltage for the EL series terminal is 24 V DC with a tolerance of – 15 % to + 20 %. It includes functions for storing and blocking encoder values using external signals.
The EL5101-1006 EtherCAT terminal supports optional 5 V up/down counter functionality for flexible applications. Additional error message inputs are available for encoder diagnostics. Frequency and period measurements are integrated in the terminal with micro increment support enhancing axis positioning. A resolution of 100 ns is available for frequency and period evaluation.
