4.5 List of Warnings and Alarms

WARNING/ALARM 2, Live zero error
This warning or alarm only appears if parameter 6-01 Live
Zero Timeout Function is configured. The signal on 1 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 a 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.
•
Check that the frequency converter programming
matches the analog signal type.
WARNING/ALARM 3, No motor
No motor is connected to the output of the frequency
converter. Check the cable connection between the
frequency converter and the motor.
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 parameter 14-12 Function at
Mains Imbalance.
Troubleshooting
•
Check the supply voltage and supply currents to
the frequency converter.
WARNING/ALARM 7, DC overvoltage
If the DC-link voltage exceeds the limit, the frequency
converter trips after a time.
Troubleshooting
•
Extend the ramp time.
•
Activate functions in parameter 2-10 Brake
Function.
•
Activate overvoltage control in
parameter 2-17 Over-voltage Control.
WARNING/ALARM 8, DC under voltage
If the DC-link voltage (DC) drops below the undervoltage
limit, the frequency converter trips after a fixed time delay.
The time delay varies with unit size.
Troubleshooting
•
Check that the supply voltage matches the
frequency converter voltage.
•
Perform an input voltage test.
WARNING/ALARM 9, Inverter overloaded
The frequency converter is about to cut out because of an
overload (too high current for too long). The counter for
electronic, thermal inverter protection issues a warning at
90% and trips at 100%, while issuing an alarm. The
frequency converter cannot be reset until the counter is
below 90%.
The fault is that the frequency converter is overloaded by
more than 100% for too long.
