  If your MAC3 Inverter displays an 'Imax Fault', it indicates an overcurrent has been detected in the pump. Check the current measurement output at parameter 36 "LoadCurrent " and set the proper value of max. current at parameter 49. Ensure the pump operates within the manufacturer's specified conditions and that the impeller isn't experiencing friction or locking.
