Or, a conflict exists between group 14, parameter 8117 NR OF AUX MOT and parameter 8118 AUTOCHNG INTERV. 1013 PAR PFA IO 2 IO configuration is not complete – the actual number of PFA motors (parameter 8127 MOTORS) does not match the PFA motors in group 14 and parameter 8118 AUTOCHNG INTERV.
ACH550-01 User's Manual Fault resetting The ACH550 can be configured to automatically reset certain faults. Refer to parameter Group 31: AUTOMATIC RESET. WARNING! If an external source, e.g. AUTO key, is selected for start command and it is active, the ACH550 may start immediately after fault reset. Flashing red LED To reset the drive for faults indicated by a flashing red LED: • Turn off the power for 5 minutes.
ACH550-01 User's Manual History For reference, the last three fault codes are stored into parameters 0401, 0412 and 0413. For the most recent fault (identified by parameter 0401), the drive stores additional data (in parameters 0402…0411) to aid in troubleshooting a problem. For example, parameter 0404 stores the motor speed at the time of the fault. To clear the fault history (all of Group 04: FAULT HISTORY parameters), follow these steps: 1. In the control panel, Parameters mode, select parameter 0401.
ACH550-01 User's Manual Alarm code Display 2003 UNDERVOLTAGE The undervoltage controller is active. Check for and correct: • undervoltage on mains. 2004 DIR LOCK The change in direction being attempted is not allowed.
