Beckhoff EL5101-0090 | EtherCAT Terminal, 1-channel encoder interface, incremental

The EL5101-0090 EtherCAT Terminal is an interface for the direct connection

of incremental encoders with differential signals (RS422) or TTL single ended

signals. 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.

The EL5101-0090 also supports TwinSAFE SC (TwinSAFE Single Channel).

This enables standard signals to be used for safety-related tasks in any network

or fieldbus.

Special features:

• supports the TwinSAFE SC technology

• save, lock, set counter

• integrated frequency and period measurement

• optionally usable as 5 V up/down counter

• microincrements

• synchronous reading of the position value via distributed clocks

• timestamp on the last-registered incremental edge

In addition, the EL5101-0090 enables the measurement of a period or frequency

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

functionality, the EL5101-0090 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.
