4.5 List of Warnings and Alarms
WARNING
Hazardous Service Procedures!
The maintenance and troubleshooting procedures
recommended in this section of the manual could result
in exposure to electrical, mechanical, or other potential
safety hazards. Always refer to the safety warnings
provided throughout this manual concerning these
procedures. Unless specied otherwise, disconnect all
electrical power including remote disconnect and
discharge all energy storing devices such as capacitors
before servicing. Follow proper lockout/tagout
procedures to ensure the power cannot be inadvertently
energised. When it is necessary to work with live
electrical components, have a qualied licensed
electrician or other individual who has been trained in
handling live electrical components perform these tasks.
Failure to follow all of the recommended safety warnings
provided, could result in death or serious injury.
WARNING/ALARM 2, Live zero error
This warning or alarm only appears if parameter 6-01 Live
Zero Timeout Function is congured. 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.
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 rectier on the frequency converter.
Options are programmed at parameter 14-12 Function at
Mains Imbalance.
CAUTION
Live Electrical Components!
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.
