DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
2001 --- Reserved
2002 --- Reserved
2003 --- Reserved
2004 DIR LOCK
The change in direction being attempted is not allowed. Do not attempt to change the direction of motor rotation, or
Chan ge parameter 1003 DIRECTION to all ow direction change (if reverse operation is safe).
2005 I/O COMM
Field bus communication has timed out. Check fa ult 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
parameter that sets the minimum (3021) and the parameter th a t sets th e 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 that sets the minimum (3022) and the parameter th a t sets th e Alarm/Fault operation (3001) .
2008 PANE L LOSS
Panel communication is lost and either the VFD is in local control mode (the control panel displays HAND), or the
VFD is in remote control mode (AUTO) and is parameterized to accept start/stop, direction or ref er en ce fr om the
control panel . To correct, check the communication lines and connections, Parameter 3002 PANEL LOSS, an d
parameters in groups 10 COMMAND INPUTS and 11 REFERENCE SELECT (if drive operation is REM).
2009 --- Reserved
2010 MOT OVERTEMP
Motor is hot, based on either the VFD estimate or on temperature feedback. This alarm warns that a Motor Overload
faul t trip may be nea r. Check for overloaded motor. Adjust th e parameters u sed for the estimate (3005 through 3009).
Check the temperature 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
motor and drive ratings match (motor is NOT undersized for th e 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* AUTORESET
This alarm warns that the drive is about to perform an automatic fault reset, which may start the motor. To
control automatic reset, 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
Pump Alternation macro.
2015 PFA INTERLOCK
This alarm warns that the PFA interlocks are active, which means that the drive cannot start any motor (when
Autochange is used), or a speed regulated motor (when Autochange is not used).
2016 --- Reserved
2017* 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
sleep function ends. To control PID sleep, use parameters 4022 thr o ugh 4026 or 4122 through 4126.
2019 ID RUN The VFD is performing an ID run.
2020 OVERRIDE Override mode is activated.
2021
START ENABLE 1
MISSING
This alarm warns that the Start Enable 1 signal is missing. To control Start Ena ble 1 function, use parameter 1608. To
correct, check the digital input configuration and the communication settings.
2022
START ENABLE 2
MISSING
This alarm warns that the Start Enable 2 signal is missing. To control Start Ena ble 2 function, use parameter1609. To
correct, check the digital input configuration and the communication settings.
2023 EMERGENCY STOP E mer gency stop is activated.
* This alar m is not indicated by a relay output, even when the relay output is configured to indicate alarm conditions, parameter 1401 RELAY OUT PUT = 5
(ALARM) or 16 (FLT/ALARM).
