Distributed Clocks: the integrated time management system in EtherCAT

Distributed Clocks: the integrated time management system in EtherCAT

The EL5122 EtherCAT Terminal is an interface for the direct connection of two incremental encoders with A and B track. Encoders with single ended signals (TTL and Open Collector) can be connected. Due to internal pull-up resistors, no external circuitry is necessary for Open Collector evaluation. Per channel a 24 V digital input is available for storing, blocking and setting the counter status. 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 supply of the encoder can be provided directly via the terminal connection points.

 

Special features:

  • save, lock, set counter
  • integrated frequency and period measurement
  • optionally usable as 5 V up/down counter
  • synchronous reading of the position value via distributed clocks

 

In addition, the EL5122 enables the measurement of a period, frequency or velocity with a resolution of 10 ns. 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). The use of encoder profiles enables simple and fast linking of the process data for Motion Control applications.
