Beckhoff EL5101-0010 | EtherCAT Terminal, 1-channel encoder interface, incremental

The EL5101-0010 EtherCAT Terminal is an interface for the direct connection

of incremental encoders with differential signals (RS422).

With a maximum input frequency of up to 5 MHz it is particularly suitable

for dynamic applications. 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 counter

• integrated frequency and period measurement

• open-circuit recognition

• synchronous reading of the position value via distributed clocks

• timestamp on the last-registered incremental edge

In addition, the EL5101-0010 enables the measurement of a period or

frequency with a resolution of 100 ns. 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.
