Fault Messages
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 specified 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 can not be inadvertently energized. When necessary to work with live electrical com-
ponents, have a qualified licensed electrician or other individual who has been trained in handling live electrical com-
ponents perform these tasks. Failure to follow all of the recommended safety warnings provided, could result in death
or serious injury.
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.
This condition can be caused by a short in a connec-
ted potentiometer or improper wiring of the potenti-
ometer.
WARNING
Live Electrical Components!
Troubleshooting: Remove the wiring from terminal
50. If the warning clears, the problem is with the cus-
tomer 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 programd
by the user in par. 6-01
Live Zero Timeout Function.
The signal on one of the analog inputs is less than
50% of the minimum value programd for that input.
This condition can be caused by broken wiring or
faulty device sending the signal.
WARNING/ALARM 3, No motor
No motor has been connected to the output of the
frequency converter. This warning or alarm will only
appear if programd by the user in par. 1-80
Function
at Stop.
Troubleshooting: Check the connection between the
drive and the motor.
WARNING/ALARM 4, Mains phase loss A phase is
missing on the supply side, or the mains voltage im-
balance is too high. This message also appears for a
fault in the input rectifier on the frequency converter.
Options are programd at par. 14-12
Function at Mains
Imbalance.
WARNING
Live Electrical Components!
Troubleshooting: Check the supply voltage and sup-
ply currents to the frequency converter.
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 frequency converter
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 frequency converter is
still active.
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit,
the frequency converter trips after a time.
Troubleshooting:
Extend the ramp time
Change the ramp type
Activate functions in par. 2-10
Brake Function
Increase par. 14-26
