Anyone know their way round an inverter that can give me some advice????
I had a call out yesterday to one of our bio systems as the boiler had shut down and the panel was giving an inverter comms fault, something along the lines of "bus alarm in inverter control" Now there are 3 of these, micromaster 440 inverters connected by uss com link to a siemens plc, Iv checked all applicable electrical connection as they had a power cut the night before, there are no alarms or faults on the inverters themselves and seem to run when set manually, i have factory reset all 3 of them and re-input the paramaters for the motors theyre running but now im at a loss, as the motors run manually im beginning to think i may have a plc fault?
Any ideas would be gratefully received
