5.5 Troubleshooting

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.
Troubleshooting
•
Check connections on all the analog input
terminals. Control card terminals 53 and 54 for
signals, terminal 55 common. MCB 101 terminals
11 and 12 for signals, terminal 10 common. MCB
109 terminals 1, 3, 5 for signals, terminals 2, 4, 6
common).
•
Check that the frequency converter 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
frequency converter.
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.
Troubleshooting
•
Check the supply voltage and supply currents to
the frequency converter.
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit, the
frequency converter trips after a time.
Troubleshooting
•
Connect a brake resistor
•
Extend the ramp time
•
Change the ramp type
•
Activate the functions in 2-10 Brake Function
•
Increase 14-26 Trip Delay at Inverter Fault
•
If the alarm/warning occurs during a power sag,
use kinetic back-up (14-10 Mains Failure)
WARNING/ALARM 8, DC under voltage
If the DC-link voltage drops below the undervoltage limit,
the frequency converter checks if a 24 V DC backup supply
is connected. If no 24 V DC backup supply is connected,
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 input voltage test.
