官方故障排除步驟
Message value: Drive object: A_INF, S_INF Reaction: OFF2 (OFF1) Acknowledge: IMMEDIATELY (POWER ON) Cause: The line synchronization is not possi ble within the monitoring time. The infeed was re-synchronized to the line suppl y because it was interrupted due to a line frequency that was determined to be either too low or too high. After 20 attempts, synchronization - and therefore also the power-on operation - were interrupted. Remedy: - check the parameterized line frequency and if required change (p0211). - check the setting of the threshold values (p0284, p0285). - check the line supply. - when a Voltage Sensing Module ( VSM) is used: check the line supply to the VSM terminals X521 or X522. - check the line supply quality. See also: p0211 (Rated line freq), p0284 (Line s upply frequency exceeded, alarm threshold), p0285 (Line supply frequency undershot, alarm threshold)
