Siemens A07971 fault code meaning

Siemens / A07971

Series: G130-G150, S120-S150

Drive: Commutation angle offset determination active

converter

Meaning: Auto determination of the commutation angle offset (encoder adjustment) is active (p1990 = 1, 3).

Possible causes

Source: SINAMICS G130_G150 P1686; SINAMICS S120_S150 P2840

Series: G210, G220

Drive: Commutation angle offset determination active

converter

Meaning: Auto determination of the commutation angle offset (encoder calibration) has been activated (p1990 = 1, 3). Note: Auto determination will be performed with the next switch-on command. See also: p1990 (Encoder calibration, commutation angle offset detection)

Possible causes

Series: S110

Drive: Commutation angle offset determination active

servo drive

Meaning: Auto determination of the commutation angle offset (encoder adjustment) is activated (p1990 = 1). Auto determination will be performed at the next switch-on command. When using a servo and fault F07414 occurs: Determination of the commutation angle offset is activated automatically (p1990 = 1) if a pole position detection procedure is set in p1980. See: p1990 (Encoder adjustment, commutation angle offset detection).
