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).

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).

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.

ID RUN

The VFD is performing an ID run.

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.

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).
