Diagnostics via configuration software of the controller
When a certain fault occurs, the 3RW5 soft starter generates an interrupt as an IO device and
sends it to the IO controller. The CPU of the controller then interrupts processing of the user
program and calls up interrupt OBs automatically. The OB number and start information already
provide you with information on the cause and type of fault.
