SOURCE: F5 KEB inverter nop problem

If using bus communications (Can, ProFi, Mod, ext), there may be a communications command (Software signal) that is not being provided. Hardware and software enable signal required to obtain LS.

Possible that the terminal on the control card is bad due to miss connection or signals outside of the rated value.

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.

What Error COM KEB mean ????i have F5 version


The KEB inverter does not have a "COM" error.

Where is this error being displayed?

Check your inverter baud rate, inverter address, communications cables and device that is being used to communicate.

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.

E.up and eoc always occurs,what the problem?


E.UP = Under voltage
Check your supply voltage.
E.OC = Over current
Check for shorts between the inverter and motor.

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

Over temperature signal from motor temperature sensor. Error can only be reset once the display reads E.nOH. Causes:
*Resistor at terminal T1:T2 > 1650 ohms * Motor overloaded (getting hot) *Temperature sensor defective
