CalibrationFault TUCTC_Events Calibration Current measurement calibration fault Current measurement calibration fault Measured offset of output phase current measurement or difference between output phase U2 and W2 current measurement is too great (the values are updated during current calibration). - Try performing the current calibration again (select Current measurement calibration at parameter 99.13). If the fault persists, contact your local ABB representative. Measured offset of output phase current measurement or difference between output phase current measurement is too great. - Try performing the current calibration again. If the fault persists, contact your local ABB representative. Current measurement offset or gain error is too big.
