Errors due to inappropriate bus cables
Due to the very high possible transmission rates, we recommend that you use only stand
ardised cables and plug connectors that at a minimum conform to the category 5 (CAT5)
in accordance with EN 50173 or ISO/IEC 11801.
When setting up the EtherCAT network, you must unconditionally follow the advice in the
relevant literature or the subsequent information and instructions in order to maintain a
stable, trouble-free system. If the system is not cabled properly, EtherCAT bus malfunc
tions can occur during operation. These can cause the CMMP-AS-...-M3 motor controller
to shut off with an error for safety reasons.
Bus termination
No external bus terminations are required. The EtherCAT technology module monitors its two ports and
terminates the bus automatically (loop-back function).
