EtherCAT plug-in modules of the EJ series

EtherCAT plug-in modules of the EJ series

The EJ5112 EtherCAT plug-in module is an interface for the direct connection of two incremental encoders with A and B track or one encoder with A, B and C track. Encoders with differential signals (RS422) or single-ended signals (TTL and open collector) can be connected. Input frequencies up to 5 MHz can be processed. In 2-channel mode, one 24 V digital input per channel is available for storing, blocking and setting the counter status; in 1-channel operation, both inputs can be used. It is also possible to set the counter to a predefined value or to lock the counter directly through the process data. The 5 V, 12 V or 24 V DC supply of the encoder can be provided directly via the module connection points.

 

Special features:

  • can be used as 1 x ABC or 2 x AB incremental encoder interface
  • save, lock, set counter
  • integrated frequency and period measurement
  • optional 5 V up/down counter
  • microincrements
  • synchronous reading of the position value via distributed clocks
  • timestamp on the last-registered incremental edge and the latch value via the 24 V digital inputs

 

In addition, the EJ5112 enables the measurement of a period, frequency or velocity with a resolution of 10 ns. A duty cycle measurement of the input signal in 1-channel mode is implemented.

With the optional interpolating microincrement functionality, the EJ5112 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, the edge at the latch input and the zero pulse track C is also available. The use of encoder profiles enables simple and fast linking of the process data for motion control applications.
