Table 32 — FAULT CODES (cont)

FAULT

CODE

FAULT NAME IN PANEL DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION

1008

PAR PFA MODE

Parameter values are inconsistent. The 9904 MOTOR CTRL MODE must = 3 (SCALAR SPEED) when 8123 PFA

ENABLE activated.

1009

PAR PCU 1

Parameter values f or power control are inconsistent or improper motor nominal frequency or speed. Check for both

of the f ol lowing:

1 < (60 * 9907 MOTOR NOM FREQ / 9908 MOTOR NOM SPEED < 16

0.8 < 9908 MOTOR NOM SPEED / (120 * 9907 MOTOR NOM FREQ / Motor poles) < 0.992

1010 OVERRIDE/PFA

CONFLICT

Override mode is enabled and PFA is activated at the same time. T h is cannot be done because PFA interlocks cannot

be observed in the override mode.

ALARM NAME

IN PANEL

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 al low direction change (if r everse operation is safe).

2005 I/O COMM

Field bus commu nication has timed ou t. Check faul t setup (3018 COMM FAU LT 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 inpu t source and connections. Check the

parameter that sets the minimum (3021) a nd 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 inpu t source and connections. Check

parameter that sets the minimum (3022) a nd the parameter that sets the 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 refer en ce from the

control panel. To correct, check the communication l ines and connections, Parameter 3002 PANEL LOS S , 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 near. Check f or over loaded motor. Adjust the para meters used 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 a nd 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 faul t 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 fu n ction 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 Th is 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 fu nction ends. To control PID sleep, use par a meters 4022 through 4026 or 4122 thro ugh 4126.

2019 ID RUN The VFD is performing an ID run.

2020 OVERRIDE Override mode is activated.

2021

START ENABLE 1

MISSING

This al a r m warn s that the S tart En a ble 1 signal is missing. To control Start Enable 1 function, use parameter 1608. To

correct, check the digital input configuration and the communication settings.

2022

START ENABLE 2

MISSING

This al a r m warn s that the S tart En a ble 2 signal is missing. To control Start Enable 2 function, use parameter1609. To

correct, check the digital input configuration and the communication settings.

2023 EMERGENCY STOP Emergency stop is activated.

* Th is a larm is not indicated by a relay output, even when th e rel a y ou tput is configured to indicate al arm con ditions, parameter 1401 RELAY OUTPUT = 5

(ALARM) or 16 (FL T/ALARM).
