Originally had to send the simovert drive for repair due to
it faulting on f11 and f26. The repair company told there had replaced
2 faulty items carried out a function test. all ok. They then returned the drive which I subsequently refitted and powered the compressor up and tried to start it only get 7301 displayed on the elektronican. Presumed that this was due to a communication problem between simovert drive and display. I telephoned the repair company and they told me they had tested
the drive by hard wiring it and not used any serial communication device. I have tried everything to try to get elektronican to communicate but as yet have had no success. I have now made a mistake by resetting the parameters and only have a list of parameters up to 500. Any help would
be greatly appreciated. Thanks J Mitchell
