Possible causes
Source: Converter SINAMICS G120, equipped with control unit CU230P-2 P495; converter SINAMICS G120C P406; SINAMICS G120P Cabinet P513
Series: G120-CU240B-E-2
Drive: Torque/speed too small
converter
Meaning: When p2193 = 1: The torque has deviated from the torque/speed envelope (too small). When p2193 = 2: The speed signal from the external encoder (see p3230) has deviated from the speed (r2169) (too small). See: p2181 (Load monitoring response)
