NOTE(S):
a. 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).
Table 25 — ACH550/ACS320 Fault Codes (cont)
DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
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 - 1412 RELAY OUTPUTS 4
- 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.
Table 26 — ACH550/ACS320 Alarm Codes
DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
Not used.
Not used.
Not used.
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 - 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.
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).
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
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 accelerate when the PID sleep
function ends. To control PID sleep, use parameters 4022 - 4026 or 4122 - 4126.
The VFD is performing an ID run.
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 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 settings.
Emergency stop is activated.
