*This alarm is not indicated by a relay output, even when the relay out-
put is configured to indicate alarm conditions (parameter 1401 RELAY
OUTPUT = 5 [ALARM] or 16 [FLT/ALARM]).
Table 52 — Fault Codes (cont)
Parameter values are inconsistent. Check that parameter 1301 AI 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 nomi-
nal power. Check the following parameters:
PAR PCU 2 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 U.S.A.)
Parameter values are inconsistent. Check the extension relay module for connection and 1410
PAR EXT RO
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
PAR FBUS
EXT1 COMMANDS = 10 (COMM)), but 9802 COMM PROT SEL = 0.
Parameter values are inconsistent. The 9904 MOTOR CTRL MODE must be = 3 (SCALAR
SPEED), when 8123 PFA ENABLE is activated.
Parameter values for power control are inconsistent or improper motor nominal frequency or
speed. Check for both of the following:
PAR PCU 1
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
CONFLICT PFA interlocks cannot be observed in the override mode.

The change in direction being attempted is not allowed. Do not attempt to change the direction
DIR LOCK 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
I/O COMM 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 connec-
AI1 LOSS tions. 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 connec-
AI2 LOSS tions. Check the 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 dis-
plays HAND), or the VFD is in remote control mode (AUTO) and is parameterized to accept
PANEL LOSS 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 COM-
MAND 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
UNDERLOAD 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.
This alarm warns that the drive is about to perform an automatic fault reset, which may start the
AUTORESET
motor. To control automatic reset, use parameter group 31 (AUTOMATIC RESET).
This alarm warns that the PFA autochange function is active. To control PFA, use parameter
group 81 (PFA) and the Pump Alternation macro.
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).
— Reserved
OFF BUTTON This alarm indicates that the OFF button has been pressed.
This alarm warns that the PID sleep function is active, which means that the motor could accel-
PID SLEEP erate 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.
This alarm warns that the Start Enable 1 signal is missing. To control Start Enable 1 function,
use parameter 1608. To correct, check the digital input configuration and the communication
MISSING
settings.
This alarm warns that the Start Enable 2 signal is missing. To control Start Enable 2 function,
use parameter 1609. To correct, check the digital input configuration and the communication
MISSING
settings.
Emergency stop is activated.
