FAULT
CODE
FAULT NAME IN PANEL DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
101--- 105 SYSTEM ERROR Error internal to the drive. Contact Carrier and report the error number.
201--- 206 SYSTEM ERROR Error internal to the drive. Contact Carrier and report the error number.
1000
PAR HZRPM
Parameter values are inconsistent. Check for any of the following:
2001 MINIMUM SPEED > 2002 MAXIMUM SPEED
2007 MINIMUM FREQ > 2008 MAXIMUM FREQ
2001 MINIMUM SPEED / 9908 MOTOR NOM SPEED is outside of the range: ---128/ +128
2002 MAXIMUM SPEED / 9908 MOTOR NOM SPEE D is outside of the range: ---128/ +128
2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ is ou tside of the range: --- 128/+128
2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: --- 128/+128
1001 PAR PFA REFNG Parameter values a re inconsistent. Check that 2007 MINIMUM FREQ is negative, when 8123 PFA ENABLE is active.
1002
PAR PFA IOC NF
Parameter values are inconsistent. The number of programmed PFA relays does not match with Interlock
configuration, when 8123 PFA ENABLE is active. Check consistency of RELAY OUT PUT parameters 1401 through
1403, a nd 1410 through 1412. Check 8117 NR OF AUX MOTORS, 8118 AUTOCHANGE INTERV, and 8120
INTERLOCKS.
1003
PAR AI SCALE
Parameter values a re inconsistent. Check th a t parameter 1301 AI 1 MIN > 1302 AI 1 MAX and that parameter 1304 AI
2 MIN > 1305 AI 2 MAX .
1004
PAR AO SCALE
Parameter values a re inconsistent. Check th a t parameter 1504 AO 1 MIN > 1505 AO 1 MAX and tha t parameter 1510
AO 2 MIN > 1511 AO 2 MAX.
1005
PAR PCU 2
Parameter values for power control are inconsistent: Improper motor nominal kVA or motor nominal power. Check
the following parameters:
1.1 < (9906 MOTOR NOM CURR * 9905 MOTOR NOM VOLT * 1.73 / PN) < 2.6
Where: 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 through 1412 RELAY
OUTPUTS 4 through 6 have non---zero values.
1007
PAR FBUS
Parameter values are inconsistent. Check that a parameter is set f or 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
ENABLE activated.
1009
PAR PCU 1
Parameter values for power control are inconsistent or improper motor nominal frequency or speed. Check for both
of the following:
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. This 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 allow direction change (if reverse operation is safe).
2005 I/O COMM
Field bus commu nication has timed out. Check fa ult setup (3018 COMM FAULT FUNC a nd 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 th e 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 th e parameter that sets the Alarm/Fault operation (3001).
2008 PANE L LOS S
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 reference from the
control panel. To correct, check the communication lines and conne ctions, Parameter 3002 PANEL LOSS, and
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 for overloaded motor. Adjust the parameters 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 f or the drive). Check the settings on para meters 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.
