Siemens F07312 fault code meaning

Series: G120X

Power supply bypass switch

converter

Meaning: Fault value (r0949, bit-coded): Bit 1: Switch feedback "closed" is missing. Bit 2: Switch feedback "open" is missing. Bit 3: Switch feedback is too slow. After switching on, forward feedback is awaited. If feedback is received only after the specified time has elapsed, a fault trip occurs. Bit 6: Power supply switch feedback does not match the bypass status. The power supply switch is closed without a bypass request when switching on or switching on the motor.

Power supply bypass switch

converter

Meaning: Fault value (r0949, bit-coded): Bit 1: Switch feedback indicating "closed" is missing. Bit 2: Switch feedback indicating "open" is missing. Bit 3: Switch feedback is too slow. After switch-on, the system waits for affirmative feedback. If feedback is received only after the specified time has elapsed, a fault trip occurs. Bit 6: Power switch feedback and bypass status mismatch. During switch-on or motor switch-on, the power switch is closed without a bypass request. See also: p1260, r1261, p1266, p1267, p1269, p1274
