5.2.1.4 Sampling rate and synchronization
The sampling rate depends on whether the box's filters are activated. The filters are disabled by default.
They are described in the chapter
Filter [ } 27] .
• If all filters are disabled,
the box works SM-synchron. In this mode the EtherCAT cycle time determines the sampling rate: in
each EtherCAT cycle the measured values are read out from the sensors.
The sensor operates internally with 10 bits up to a cycle time of 1 ms. Below this, the resolution drops
to 8 bits. The minimum cycle time is 200 µs.
• If at least one filter is enabled,
the box runs in FreeRun mode with a sampling rate adjustable via CoE index 0xF800:0D "Filter
sampling rate".
If the sampling rate is increased to 2500 Hz or 5000 Hz, the resolution is reduced to 8-bit.
