Position measurement EP5001 Absolute encoder | SSI encoder EtherCAT Box 278 The EP5001 EtherCAT Box is an interface for the direct connection of SSI encoders with differential inputs (RS485).The interface circuit generates a pulse for reading the encoder and makes the incoming data stream available to the controller as a data word in the process image. Various operating modes, transmission frequencies and bit widths can be permanently stored in a control register. The encoder is connected via an 8-pin M12 socket.

EP51xx, ER51xx Position measurement Incremental encoder | 24 V DC The EP51x1/ER51x1 EtherCAT Box is an interface for the direct connection of incremental encoders with 24 V DC inputs. Both types are also available as ERxxxx. A 32/16 bit counter with a quadrature decoder and a 32/16 bit latch for the zero pulse can be read, set or enabled. Interval measurement with a resolution of up to 100 ns is possible. The gate input allows the counter to be halted. Due to the optional interpolating microincrement function, the interfaces can supply even more precise axis positions for dynamic axes. In addition, it supports the synchronous reading of the encoder value together with other input data in the EtherCAT system via highprecision EtherCAT distributed clocks (DC). The encoder is connected via an 8-pin M12 socket. In the M12 version not all signals are available.
