Siemens MICRO MASTER and MIDI MASTER Error F002: Overcurrent

Inverter · taken from the manufacturer’s manual, pages cited

Fault codeF002

Overcurrent happens when the motor draws more current than the inverter can handle, possibly due to mismatched power or cable issues. The manual's first action is: “Check whether the motor power corresponds to the inverter power. Check that the cable length limits have not been exceeded. Check motor lead and motor for short-circuits and earth faults. Check whether the motor parameters (P081 – P086) correspond with the motor being used. Check the stator resistance (P089). Increase the ramp-up time (P002). Reduce the boost set in P078 and P079. Check whether the motor is obstructed or overloaded.”
