Run the motor with no load to see if it functions with no load.
If the system functions with no load, you may still need to increase your acceleration time to reduce the current demand.

What is the part# / serial# of the inverter in question?

E oc in f4

Error Over Current.

Disconnect motor leads at U/V/W terminals and run the inverter to determine if the problem is internal or external of the inverter.

If it is external then you are looking for a shorted winding in the motor or a shorted motor lead between the inverter and the motor.

Need a Way to adjust dr.2 Rated Motor Current value. Combivert F4-C

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.
