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 | |
Change parameter 1003 DIRECTION to allow direction change (if reverse operation is safe). | |||
|
| ||
|
|
| |
2005 |
| Field bus communication has timed out. Check fault setup (3018 COMM FAULT FUNC and 3019 COMM FAULT | |
I/O COMM | 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 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 that sets the minimum (3022) and the parameter that sets the Alarm/Fault operation (3001). | |||
|
| ||
|
|
| |
|
| Panel communication is lost and either the VFD is in local control mode (the control panel displays HAND), or the | |
2008 | PANEL LOSS | VFD is in remote control mode (AUTO) and is parameterized to accept start/stop, direction or reference from the | |
control panel. To correct, check the communication lines and connections, Parameter 3002 PANEL LOSS, and | |||
|
| ||
|
| parameters in groups 10 COMMAND INPUTS and 11 REFERENCE SELECT (if drive operation is REM). | |
|
|
| |
2009 | Reserved | ||
|
|
| |
2010 |
| Motor is hot, based on either the VFD estimate or on temperature feedback. This alarm warns that a Motor Overload | |
MOT OVERTEMP | fault trip may be near. Check for overloaded motor. Adjust the parameters used for the estimate (3005 through 3009). | ||
|
| Check the temperature sensors and Group 35 parameters. | |
|
|
| |
2011 |
| Motor load is lower than expected. This alarm warns that a Motor Underload fault trip may be near. Check that the | |
UNDERLOAD | motor and 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* | 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 through 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 | This alarm warns that the Start Enable 1 signal is missing. To control Start Enable 1 function, use parameter 1608. To | |
MISSING | correct, check the digital input configuration and the communication settings. | ||
| |||
|
|
| |
2022 | START ENABLE 2 | This alarm warns that the Start Enable 2 signal is missing. To control Start Enable 2 function, use parameter1609. To | |
MISSING | correct, check the digital input configuration and the communication settings. | ||
| |||
|
|
| |
2023 | EMERGENCY STOP | Emergency stop is activated. | |
|
|
|
*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) or 16 (FLT/ALARM).
