5000 FLUX
The tolerance is ± 5°C. The temperature fault
cannot be reset, until the temperature of the
heat-sink is below 60°C.
The fault could be the following:
- Ambient temperature too high
- Too long motor cable
ALARM: 30
Motor phase U missing
(MISSING MOT.PHASE U):
Motor phase U between frequency converter
and motor is missing.
Turn off the frequency converter and check
motor phase U.
ALARM: 31
Motor phase V missing
(MISSING MOT.PHASE V):
Motor phase V between frequency converter
and motor is missing.
Turn off the frequency converter and check
motor phase V.
ALARM: 32
Motor phase W missing
(MISSING MOT.PHASE W):
Motor phase W between frequency converter
and motor is missing.
Turn off the frequency converter and check
motor phase W.
WARNING/ALARM: 34
Profibus communication fault
(PROFIBUS COMMUNICATION FAULT):
The profibus on the communication option
card is not working.
WARNING: 35
Out of speed range
(OUT OF SPEED RANGE):
This warning is active if the output frequency has
reached its Output speed low limit (parameter 201)
or Output speed high limit (parameter 202).
WARNING/ALARM: 36
Mains failure (MAINS FAILURE):
This warning/alarm is only active if the supply voltage
to the frequency converter is lost and if parameter 407
Mains fault has been set to another value than OFF .
If parameter 407 has been set to Contr. ramp-down
trip [2], the frequency converter will first give a warning
and then ramp down and trip, while giving an alarm.
Check the fuses to the frequency converter.
ALARM: 37
Inverter fault (Inverter fault):
IGBT or the power card is defective. Contact
your Danfoss supplier.
Auto-optimisation warnings
Automatic motor adaptation has stopped, since some
parameters have probably been set wrongly, or the
motor used is too big/small for AMA to be carried out.
A choice must thus be made by pressing [CHANGE
DATA] and choosing ‘Continue ’ + [OK] or ‘Stop ’ + [OK].
If parameters need to be changed, select
‘Stop ’ ; start up AMA all over.
WARNING: 39
CHECK P.104,106
The setting of parameter 102, 104 or 106
is probably wrong. Check the setting and
choose ‘Continue ’ or ‘Stop ’ .
WARNING: 40
CHECK P.103,105
The setting of parameter 102, 103 or 105
is probably wrong. Check the setting and
choose ‘Continue ’ or ‘Stop ’ .
WARNING: 41
MOTOR TOO BIG
The motor used is probably too big for AMA to
be carried out. The setting in parameter 102
may not match the motor. Check the motor
and choose ‘Continue
’
or ‘Stop
’
.
WARNING: 42
MOTOR TOO SMALL
The motor used is probably too small for AMA
to be carried out. The setting in parameter 102
may not match the motor. Check the motor
and choose ‘Continue ’ or ‘Stop ’ .
ALARM: 43
Brake fault (BRAKE FAULT)
A fault has arisen on the brake. The text shown in
the display indicates a fault message. The figure
after the text is the fault code that can be seen
in the fault log, parameter 615.
Brake check failed (BRAKE CHECK FAILED) [0]
The brake check carried out during power-up indicates
that the brake has been disconnected. Check
whether the brake has been connected correctly
and that it has not been disconnected.
Brake resistor short-circuited
(BRAKE RESISTOR FAULT) [1]
The brake output has short-circuited. Replace
the brake resistor.
Brake IGBT short-circuited
