Interference From Equipment - Beckhoff EL47 Series Documentation

Commissioning
The application of these functions using the Beckhoff TwinCAT System Manager is described in section
Process data and configuration [} 145].
SYNC0 and SYNC1 pulse with several EtherCAT slaves
This approach of matching the SYNC0 and SYNC1 pulses of several EtherCAT slaves is not limited
to EL4732.
All EtherCAT slaves supporting the distributed clock function can be correlated relatively freely in
this way.
CAUTION! Risk of device damage!
The above notes and information should be used advisedly.
The EtherCAT master automatically allocates SYNC0 and SYNC1 settings that support reliable and timely
process data acquisition.
User intervention at this point may lead to undesired behavior.
If these settings are changed in the System Manager, no plausibility checks are carried out on the software
side. Correct function of the terminal with all conceivable setting options cannot be guaranteed.

Interference from equipment

This fast analog EtherCAT terminal may pick up high-frequency superimposed interference signals from
other equipment (e.g. proportional valves, stepper motor or DC motor output stages). In order to ensure
trouble-free operation, we recommend using separate power supply units for the terminals and the
equipment causing interference. The cables should be screened.
