8.4.1 Fault Messages

The warning/alarm information below defines the warning/
alarm condition, provides the probable cause for the
condition, and details a remedy or troubleshooting
procedure.
WARNING 1, 10 Volts low
The control card voltage is below 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA or minimum 590 Ω.
8 8
This condition can be caused by a short in a connected
potentiometer or improper wiring of the potentiometer.
Troubleshooting: Remove the wiring from terminal 50. If
the warning clears, the problem is with the customer
wiring. If the warning does not clear, replace the control
card.
WARNING/ALARM 2, Live zero error
This warning or alarm will only appear if programmed by
the user in AN-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. This condition can be
caused by broken wiring or faulty device sending the
signal.
Troubleshooting
Check connections on all the analog input
terminals. Control card terminals 53 and 54 for
signals, terminal 55 common. OPCGPIO terminals
11 and 12 for signals, terminal 10 common.
OPCAIO terminals 1, 3, 5 for signals, terminals 2,
4, 6 common).
Check that the drive programming and switch
settings match the analog signal type.
Perform Input Terminal Signal Test.
WARNING/ALARM 3, No motor
No motor has been connected to the output of the drive.
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 drive. Options are
programmed at SP-12 Function at Line Imbalance.

Warning Alarm/Trip

Troubleshooting: Check the supply voltage and supply
currents to the drive.
WARNING 5, DC link voltage high
The intermediate circuit voltage (DC) is higher than the
high voltage warning limit. The limit is dependent on the
drive voltage rating. The unit is still active.
WARNING 6, DC link voltage low
The intermediate circuit voltage (DC) is lower than the low
voltage warning limit. The limit is dependent on the drive
voltage rating. The unit is still active.
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit, the
drive trips after a time.
Troubleshooting
WARNING/ALARM 8, DC under voltage
If the intermediate circuit voltage (DC link) drops below
the under voltage limit, the drive checks if a 24V DC
backup supply is connected. If no 24V DC backup supply is
connected, the drive trips after a fixed time delay. The
time delay varies with unit size.
Troubleshooting:
WARNING/ALARM 9, Inverter overload
The drive is about to cut out because of an overload (too
high current for too long). The counter for electronic,
thermal inverter protection gives a warning at 98% and
trips at 100%, while giving an alarm. The drive cannot be
reset until the counter is below 90%.
The fault is that the drive is overloaded by more than
100% for too long.
