Tip!
The errors mentioned before indicate that a physical error has occurred in the bus system.
Possible causes are:
• Several nodes with identical node address
• Wrong baud rate of one or several nodes
• Too high cable length
• Too many or no terminating resistors
• Too high bus load/too many data telegrams
(e.g. since a node permanently transmits event-controlled due to data changes of an
analog signal/actual value.)
• EMC interferences on the system bus
(e.g. since the CAN bus cable next to the motor cable is unshielded.)
displays whether such an error is active.
