what is no_PO error


no_PU = No power unit. 24Vdc is being supplied to the control card with no AC voltage (230 or 400) being supplied to L1/L2/L3.

Verify AC voltage is present at L1/L2/L3.
*If not present, apply voltage and no_PU should clear. *If present and unit still no_PU, there is a problem with the power stage. At that point unit should be replaced or repaired.

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.

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
