Distributed Clocks: the integrated time management system in EtherCAT

Distributed Clocks: the integrated time management system in EtherCAT

The EL5021 EtherCAT Terminal is used for the direct connection of a measuring probe or encoder with sinusoidal, differential voltage output 1 VPP. Input frequencies of max. 250 kHz can be evaluated. The current counter reading can be zeroed (reset) or stored separately via the C track of the encoder, which is also called reference mark. The 5 V supply to the encoder is provided directly via the terminal connection points. The EL5021 features amplitude and frequency error detection of the input signals.

 

Special features:

  • store, lock, set counter
  • diagnosis: frequency error and amplitude error of input signals
  • integrated frequency measurement
  • integrated 5 V DC encoder operating voltage

 

The analog input signal is processed, interpolated and made available as a 32-bit count value. The count value is a combination of the number of whole periods, max. 24 bits, and the value within one sine period, with max. 13 bit resolution. The EL5021 also provides an internal frequency measurement. 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 process data to motion control applications.
