Message value: Line frequency: %1 Drive object: A_INF, S_INF Reaction: NONE Acknowledge: NONE Cause: The actual line frequency f_line is lower than the parameterized alarm threshold (f_line < p0211 * p0285). The alarm can be output in two operating states: 1. During the power-on phase of the infeed unit. Consequence: Synchronization of the infeed to the line supply is interrupted and is restarted. 2. While the infeed is operational. Consequence: The infeed remains in the operating (run) state and al arm A06351 is output. This signifies a critical operational fault. Alarm value (r2124, floating point): Current line frequency determined. See also: p0285 (Line supply frequency undershot, alarm threshold) SINAMICS-Alarms Remedy: - check the parameterized line frequency and if required change (p0211). - check the alarm threshold (p0285). - check the line supply. - check the line supply quality. See also: p0211 (Rated line freq), p0285 (Line supply frequency undershot, alarm threshold)
