Table 6.2 Warnings and Alarms Code List
1)
These faults may be caused by mains distortions. Installing Danfoss Line Filter may rectify this problem.
The alarm words, warning words and extended status
words can be read out via serial bus or optional fieldbus
for diagnosis.
WARNING/ALARM 2, Live zero error
This warning or alarm only appears if programmed in
6-01 Live Zero Timeout Function. The signal on one of the
analog inputs is less than 50% of the minimum value
programmed for that input. Broken wiring or faulty device
sending the signal can cause this condition.

X X 24 V DC may be overloaded.
X Wrong setting for motor voltage and/or motor current.
X Motor current is too low. Check settings.
X The motor is too big for the AMA to operate.
X The motor is too small for the AMA to operate.
The parameter values of the motor are outside of the
X
acceptable range. AMA will not run.
X The user has interrupted the AMA.
X
X Contact your Danfoss supplier.
X Frequency converter overload.
X
Actual motor current has not exceeded "release brake"
X
current within "start delay" time window.
The cut-out temperature of the control card is 80 °C.
X X
X A new option is detected or a mounted option is
removed.

X All parameter settings are initialised to default settings.
Occurs in IT mains when the frequency converter coasts
and V DC is higher than 830 V. Energy on DC link is
consumed by the motor. This function can be enabled/
disabled in 0-07 Auto DC Braking.

Occurs when using a wrong password for changing a
password-protected parameter.
Troubleshooting
•
Check connections on all the analog input
terminals. Control card terminals 53 and 54 for
signals, terminal 55 common.
•
Check that the frequency converter programming
and switch settings match the analog signal type.
•
Perform Input Terminal Signal Test.
WARNING/ALARM 4, Mains phase loss
A phase is missing on the supply side, or the mains
voltage imbalance is too high. This message also appears
for a fault in the input rectifier on the frequency converter.
Options are programmed at 14-12 Function at Mains
Imbalance.
