Beckhoff EL5151 | EtherCAT Terminal, 1-channel encoder interface, incremental

The EL5151 EtherCAT Terminal is an interface for the direct connection of

one incremental encoder (24 V HTL). An additional 24 V digital input is

available for storing or blocking the counter status. As an alternative, the

EL5151 can be used as a up/down counter.

The 24 V supply of the encoder can be provided directly via the terminal

connection points.

Special features:

• save, lock, set counter

• integrated frequency and period measurement

• optionally 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 EL5151 enables the measurement of a period or frequency

with a resolution of 100 ns. With the optional interpolating microincrement

functionality, the EL5151 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.
