DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
Error internal to the drive. Contact Carrier and report the error number.
Error internal to the drive. Contact Carrier and report the error number.
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 SPEED is outside of the range: ---128/+128
2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: --- 128/+128
2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ is outside of the range: --- 128/+128
Parameter values are inconsistent. Check that 2007 MINIMUM FREQ is negative, when 8123 PFA ENABLE is active.
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 OUTPUT parameters 1401 through
1403, and 1410 through 1412. Check 8117 NR OF AUX MOTORS, 8118 AUTOCHANGE INTERV, and 8120
INTERLOCKS.
Parameter values are inconsistent. Check that parameter 1301 AI 1 MIN > 1302 AI 1 MAX and that parameter 1304 AI
2 MIN > 1305 AI 2 MAX.
Parameter values are inconsistent. Check that parameter 1504 AO 1 MIN > 1505 AO 1 MAX and that parameter 1510
AO 2 MIN > 1511 AO 2 MAX.
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)
Parameter values are inconsistent. Check the extension relay module for connection and 1410 through 1412 RELAY
OUTPUTS 4 through 6 have non ---zero values.
Parameter values are inconsistent. Check that a parameter is set for field bus control (e.g., 1001 EXT1 COMMANDS
= 10 (COMM)), but 9802 COMM PROT SEL = 0.
Parameter values are inconsistent. The 9904 MOTOR CTRL MODE must = 3 (SCALAR SPEED) when 8123 PFA
ENABLE activated.
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
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.

DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION

Reserved
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).
Field bus communication has timed out. Check fault 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.
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).
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
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).
Reserved
Motor is hot, based on either the VFD estimate or on temperature feedback. This alarm warns that a Motor Overload
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.
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 the drive). Check the settings on parameters 3013 to
3015.
Motor is operating in the stall region. This alarm warns that a Motor Stall fault trip may be near.
