671003 PAR AI SCALE Parameter values are inconsistent. Check that parameter 1301 AI 1 MIN > 1302 AI 1 MAX and that parameter 1304 AI 2MIN > 1305 AI 2 MAX.1004 PAR AO SCALE Parameter values are inconsistent. Check that parameter 1504 AO 1 MIN > 1505 AO 1 MAX and that parameter 1510 AO 2MIN > 1511 AO 2 MAX.1005 PAR PCU 2Parameter values for power control are inconsistent: Improper motor nominal kVA or motor nominal power. Check thefollowing parameters:1.1 < (9906 MOTOR NOM CURR * 9905 MOTOR NOM VOLT * 1.73 / PN) < 2.6Where: PN = 1000 * 9909 MOTOR NOM POWER (if units are kW) or PN = 746* 9909 MOTOR NOM POWER (if units are HP, e.g., in US)1006 PAR EXT RO Parameter values are inconsistent. Check the extension relay module for connection and 1410 - 1412 RELAY OUTPUTS 4- 6 have non-zero values.1007 PAR FBUS Parameter values are inconsistent. Check that a parameter is set for field bus control (e.g., 1001 EXT1 COMMANDS = 10(COMM)), but 9802 COMM PROT SEL = 0.1008 PAR PFA MODE Parameter values are inconsistent. The 9904 MOTOR CTRL MODE must = 3 (SCALAR SPEED) when 8123 PFA ENABLEactivated.1009 PAR PCU 1Parameter values for power control are inconsistent or improper motor nominal frequency or speed. Check for both of thefollowing:1 < (60 * 9907 MOTOR NOM FREQ / 9908 MOTOR NOM SPEED < 160.8 < 9908 MOTOR NOM SPEED / (120 * 9907 MOTOR NOM FREQ / Motor poles) < 0.9921010 OVERRIDE/PFACONFLICTOverride mode is enabled and PFA is activated at the same time. This cannot be done because PFA interlocks cannot beobserved in the override mode.Table 33 — ACH550/ACS320 Fault Codes (cont)FAULTCODE FAULT NAME IN PANEL DESCRIPTION AND RECOMMENDED CORRECTIVE ACTIONTable 34 — ACH550/ACS320 Alarm CodesALARMCODE ALARM NAME IN PANEL DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION2001 — Not used.2002 — Not used.2003 — Not used.2004 DIR LOCK The change in direction being attempted is not allowed. Do not attempt to change the direction of motor rotation, or Changeparameter 1003 DIRECTION to allow direction change (if reverse operation is safe).2005 I/O COMM Field bus communication has timed out. Check fault setup (3018 COMM FAULT FUNC and 3019 COMM FAULT TIME).Check communication settings (Group 51 or 53 as appropriate). Check for poor connections and/or noise on line.2006 Al1 LOSS Analog input 1 is lost, or value is less than the minimum setting. Check input source and connections. Check the parameterthat sets the minimum (3021) and the parameter that sets the Alarm/Fault operation (3001).2007 Al2 LOSS Analog input 2 is lost, or value is less than the minimum setting. Check input source and connections. Check parameter thatsets the minimum (3022) and the parameter that sets the Alarm/Fault operation (3001).2008 PANEL LOSSPanel communication is lost and either the VFD is in local control mode (the control panel displays HAND), or the VFD is inremote control mode (AUTO) and is parameterized to accept start/stop, direction or reference from the control panel. Tocorrect, check the communication lines and connections, Parameter 3002 PANEL LOSS, and parameters in groups 10COMMAND INPUTS and 11 REFERENCE SELECT (if drive operation is REM).2009 — Reserved2010 MOT OVERTEMPMotor is hot, based on either the VFD estimate or on temperature feedback. This alarm warns that a Motor Overload faulttrip may be near. Check for overloaded motor. Adjust the parameters used for the estimate (3005 - 3009). Check thetemperature sensors and Group 35 parameters.2011 UNDERLOAD Motor load is lower than expected. This alarm warns that a Motor Underload fault trip may be near. Check that the motorand drive ratings match (motor is NOT undersized for the drive). Check the settings on parameters 3013 to 3015.2012 MOTOR STALL Motor is operating in the stall region. This alarm warns that a Motor Stall fault trip may be near.2013 aNOTE(S):a. This alarm is not indicated by a relay output, even when the relay output is configured to indicate alarm conditions, parameter 1401 RELAY OUTPUT = 5 (ALARM) or16 (FLT/ALARM).AUTORESET This alarm warns that the drive is about to perform an automatic fault reset, which may start the motor. To control automaticreset, use parameter group 31 (AUTOMATIC RESET).2014 AUTOCHANGE This alarm warns that the PFA autochange function is active. To control PFA, use parameter group 81 (PFA) and the PumpAlternation macro.2015 PFA INTERLOCK This alarm warns that the PFA interlocks are active, which means that the drive cannot start any motor (when Autochange isused), or a speed regulated motor (when Autochange is not used).2016 — Reserved2017a OFF BUTTON This alarm indicates that the OFF button has been pressed.2018 PID SLEEP This alarm warns that the PID sleep function is active, which means that the motor could accelerate when the PID sleepfunction ends. To control PID sleep, use parameters 4022 - 4026 or 4122 - 4126.2019 ID RUN The VFD is performing an ID run.2020 OVERRIDE Override mode is activated.2021 START ENABLE 1MISSINGThis alarm warns that the Start Enable 1 signal is missing. To control Start Enable 1 function, use parameter 1608. Tocorrect, check the digital input configuration and the communication settings.2022 START ENABLE 2MISSINGThis alarm warns that the Start Enable 2 signal is missing. To control Start Enable 2 function, use parameter 1609. Tocorrect, check the digital input configuration and the communication settings.2023 EMERGENCY STOP Emergency stop is activated.
