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.

Eoc alam


E.OC is an over current error.

The inverter is sensing a short on the U/V/W terminals. This could be a shorted motor, motor leads and an internal short in the inverter.

Disconnect the motor leads from the inverter, and run the inverter as you normally would.

If the E.OC error does not occur the short is external of the inverter.
If the E.OC occurs, then the short is internal to the inverter.

Inverter IGBT failuair again& again


If you are continually replacing the inverters, there may be an external issue causing the failures.

If you are continually replacing IGBT's on the same inverter, then there is most likely a problem with the circuit controlling the IGBT's.

I have a prblem in the F5 keb combivert it's show Error E.OC & E.puci & E.Puch could you please advice us with the proper solution thanks


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
