Short Description
The EJ5021 EtherCAT plug-in module 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 signal distribution board (UP). The EJ5021 features amplitude and frequency error detection of the input signals.
