Beckhoff EP5101 EtherCAT Box incremental encoder interface

Thursday, 15 September, 2011 | Supplied by: Beckhoff Automation Pty Ltd


The EP5101 EtherCAT Box is an interface for the direct connection of incremental encoders with differential inputs (RS485). Due to the optional interpolating microincrements functionality, the EP5101 can supply 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.

The compact format of the interface, of 126 x 30 x 26.5 mm (H x W x D), makes it suitable for applications where space is tight. In addition to the stepper motor and DC motor box modules, which are also equipped with an encoder interface, stand-alone encoders for the measurement of rotation and length can also be directly connected in the field using the EP5101 incremental encoder interface. The interface supports any feedback system with an RS485 interface. The encoder is connected either via an M12 socket or via a D-sub interface.

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. The gate input allows the counter to be disabled; the latch input accepts the counter reading on the rising edge.

With the Beckhoff EtherCAT Box modules with IP67 protection, EtherCAT technology is now also usable without a control cabinet.
