Siemens F0022 fault code meaning

Series: MM430

Hardware monitoring active

converter

Meaning: This fault occurs in the following events (r0947=22 and r0949=1): (1) DC intermediate circuit overcurrent status=IGBT short circuit; (2) braking unit short circuit; (3) ground fault; (4) I/O board incorrectly inserted. The same faults also occur for the following frame sizes: frame sizes A~C (1), (2), (3), (4); frame sizes D~E (1), (2), (4); frame size F (1), (2). The following faults occur only in frame size FX/GX: If r0947=22 and fault value r0949=12 or 13 or 14, a UCE fault is indicated. If r0947=22 and fault value r0949=21 (power off and on again), a I2C bus fault is indicated. Note: All these faults generate a single signal for the power module, so the actual fault cannot be determined.

Meaning: This fault occurs in the following events (r0947 = 22 and r0949 = 1): (1) DC link overcurrent status = IGBT short circuit; (2) braking unit short circuit; (3) ground fault; (4) I/O board not inserted correctly. The same faults also occur in the following frame sizes: Frame sizes A~C: (1), (2), (3), (4); frame sizes D~E: (1), (2), (4); frame size F: (1), (2). The following faults occur only in frame size FX/GX: If r0947 = 22 and fault value r0949 = 12 or 13 or 14, a UCE fault is indicated. If r0947 = 22 and fault value r0949 = 21 (power off and on again), a I2C bus fault is indicated. Note: All these faults are assigned to a single power module signal, so the actual fault cannot be determined.
