Automatic calibration failure occurs when the motor is not connected to the inverter, requiring manual entry of stator resistance if the issue persists after reconnection. The manual's first action is: “Motor not connected to inverter – connect motor. If the fault persists, set P088 = 0 and then enter the stator resistance of the motor into P089 manually.”
