Information About EL5151
The Beckhoff EL5151 EtherCAT Terminal is designed for direct connection to one incremental encoder (24 V HTL) and includes an additional 24 V digital input for storing or blocking the counter status. It can also function as a 24 V up/down counter. The terminal supplies 24 V power directly to the encoder via connection points.
Key features:
Save, lock, and set counter functions
Integrated frequency and period measurement
Optional 24 V up/down counter functionality
Microincrement capability
Synchronous position value reading via distributed clocks
Timestamp for the last-registered incremental edge
The EL5151 measures period or frequency with 100 ns resolution and offers optional interpolating microincrement functionality for precise axis positions in dynamic applications. It supports synchronous reading of encoder values and other input data within the EtherCAT system using high-precision distributed clocks (DC). Encoder profiles simplify and accelerate process data linking for motion control applications.
