Siemens A07929 fault code meaning

Siemens / A07929

Series: G110M, G115D, G120D, G120X, G120XA

Drive: Motor cannot be detected

converter

Meaning: The current after the inverter pulses are enabled is too small to detect the motor.

Possible causes

Series: G120-CU240B-E-2

Drive: Motor cannot be detected

converter

Meaning: The current is too small to detect the motor after the inverter pulses are enabled. Note: For vector control and induction motors, fault F07902 is output after the warning. See: p2179 (Initial load detection current limit)

Possible causes

Source: SINAMICS G120 Control Unit CU240B_E-2 P676

Series: G120-CU250S-2

Drive: Motor cannot be detected

converter

Meaning: The current is too low after the inverter pulses are enabled, and the motor cannot be identified. Note: - With vector control and an induction motor, fault message F07902 occurs after this alarm. See: p2179 (Initial load detection current limit).

Series: G200, G210, G210X, S220

Drive: Motor cannot be detected

converter

Meaning: The current after inverter pulses are enabled is too small to detect the motor. Note: For vector control with an induction motor, fault F07902 is issued after the alarm. This is not evaluated for vector control with a synchronous motor. See also: p2179 (Initial load identification current limit).
