The EP5101 EtherCAT Box from BECKHOFF Automation is an interface for the direct connection of incremental encoders with differential inputs (RS485).  

The optional interpolating micro-increments functionality enables the EP5101 to supply even more precise axis positions for dynamic axes. It supports the synchronous reading of the encoder value together with other input data in the EtherCAT system via high-precision EtherCAT Distributed Clocks (DC).  

Measuring only 126mm H x 30mm W x 26.5mm D, the compact form of the EP5101 EtherCAT Box makes it particularly suitable for space constrained applications.  

In addition to the stepper motor and DC motor box modules, which are also equipped with an encoder interface, standalone encoders for the measurement of rotation and length can also be directly connected in the field using the EP5101 incremental encoder interfaces.  

The EP5101 supports any feedback system with an RS485 interface. The encoder is connected via an M12 socket (EP5101-0002) or a D-sub interface (EP5101-0011).  

A 32-/16-bit counter with quadrature decoder as well as a 32-/16-bit latch for the zero pulse can be read, set or activated. Incremental encoders with a fault signal output can be connected to the status input of the EP5101.  

A period measurement with a resolution of up to 100 ns is possible. While the gate input allows the counter to be disabled, the latch input accepts the counter reading on the rising edge.  

The Beckhoff EtherCAT Box modules feature IP 67 protection allowing EtherCAT technology to be used without a control cabinet.  

Signals sensitive to interference no longer have to be transmitted over long distances, thanks to the direct EtherCAT interface that ensures the high performance of EtherCAT is retained in each module.
