Danfoss VLT 5008 Operating Instructions

VLT
®
5000 Series
Warning: There is a risk of substantial power
being transmitted to the brake resis- tor if
the brake transistor has short-circuited.
ALARM: 29
Heat sink temperature too high
(HEATSINKOVERTEMP.):
If the enclosure is IP 00 or IP 20/NEMA 1, the cut-out
temperature of the heat-sink is 90°C. If IP 54 is
used, the cut-out temperature is 80°C.
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
- Too high switching frequency.
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.
ALARM: 33
Quick discharge not OK
(QUICK DISCHARGE NOT OK):
Check whether a 24 Volt external DC supply has
been connected and that an external brake/discharge
resistor has been fitted.
WARNING/ALARM: 34
Fieldbus communication fault
(FIELDBUS COMMUNICATION FAULT):
The fieldbus on the communication option
card is not working.
WARNING: 35
Out of frequency range
(OUT OF FREQUENCY RANGE):
This warning is active if the output frequency has
reached its Output frequency low limit (parameter 201)
or Output frequency high limit (parameter 202). If
the frequency converter is in Process control, closed
loop (parameter 100), the warning will be active in the
display. If the frequency converter is in another mode
than Process control, closed loop, bit 008000 Out of
frequency range in extended status word will be active,
while there will be no warning in the display.
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’;startupAMAallover.
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’.
