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

E.puci error

E.puci = Power Unit Code Invalid.

When the inverter is powered up the power stage can not be identified by the control card or the power stage is the wrong type for the control card.

Typically can not be reset and unit needs to be repaired or replaced.

Contact OEM of machine or KEB for additioanl support

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.

KEB 07 F5 Error code E. Puch what will cause this error and how do i clear it

E.puch means that at power up the control card did recognized the power stage as different than last time it powered up.

This is normal when the control card is changed. If the control card has not been changed, there is a problem between the power stage and the control card.

Initialize the value at sy.03 to reset the error.
