Siemens | F002 Fault ^new^

Less common, but damaging. If the incoming AC line voltage is consistently above the drive's rating (e.g., 500V AC on a 400V drive), the rectified DC voltage will be proportionally higher.

It is crucial to distinguish F002 from F001 (Overcurrent). While both relate to current, F001 usually involves a short circuit between phases or a massive mechanical overload. F002 specifically implies a leakage path to the earth ground. siemens f002 fault

Disconnect the motor and test the insulation of cables and motor windings with a megohmmeter (typically at 1000V+). 3. Internal Hardware Verification Less common, but damaging
