Re: Need a Way to adjust dr.2 Rated Motor Current value....
It sounds like you may have a thermal issue causing the fault trigger of the E.OC error. This coould be an issue with the motor or the inverter getting too hot. Once the system trips into error it is allowed to cool a little and you can run again for a while.
What is the actual part# and serial # of the inverter that you are having problems with?
Since they system has been running, I would not suggest aultering the voltage/hz curves in the inverter because of an E.OC error.

E.puci During the initialization the power circuit could not be recognized as invalid. E.puch power unit changed power unit identification was changed, with a avalid power circuit this error can be reset by writting to SY.3. If the value displayed in SY.3 is written, only the power-cricuit dependent parameters are reinitialized. if any other value is written, then the default set is loaded . On some systems after writing SY.3 a power-On -Reset is necessary........ E.OC Overcurrent
