Warning Words, Extended Status Words And Alarm Words - Danfoss VLT DMS 300 Manual

below 158 °F (70 °C). The tolerance is ± 10%. The
temperature can be caused by the following:
- The ambient temperature too high.
- Motor cable too long.
- Too high AC line voltage.
ALARM 37-45: Internal fault
Internal faults 0-8 will be indicated in LED's Alarm,
Warning, Bus, Status as a flashing code.
Alarm 37, internal fault number 0: Communication
fault between control card and BMC2.
Alarm 38, internal fault number 1: Flash EEPROM
fault on control card.
Alarm 39, internal fault number 2: RAM
fault on control card
Alarm 40, internal fault number 3: Calibration
constant in EEPROM.
Alarm 41, internal fault number 4: Data
values in EEPROM.
Alarm 42, internal fault number 5: Fault in
motor parameter database.
Alarm 43, internal fault number 6: General
power card fault.
Alarm 44, internal fault number 7: Minimum software
version of control card or BMC2
Alarm 45, internal fault number 8: I/O fault (digital
input/output, relay or analog input/output)
NOTE
When restarting after an alarm 38-45, the
VLT frequency converter will display an
alarm 37. In parameter 615 the actual
alarm code can be read.
ALARM 50: AMT not possible
One of the following three possibilities can occur:
- The calculated R value falls outside permitted limits.
S
- The motor current in at least one of the
motor phases is too low.
- The motor in use is probably too small for AMT
calculations to be performed.
ALARM 51: AMT Fault re. nameplate data
192
Decentral Solutions
There is inconsistency between the registered motor
data. Check the motor data for the relevant setup.
ALARM 54: AMT incorrect motor
AMT cannot be performed on the motor being used.
ALARM 55: AMT timeout
Calculations are taking too long, possibly due
to noise on the motor cables.
ALARM 56: AMT warning during AMT
A variable frequency drive warning is given while
AMT is being performed.
WARNING 99: Locked
See parameter 18.
Warning words, extended status words
and alarm words
Warning words, status words and alarm words
appear in the display in Hex format. If there are
several warnings, status words or alarms, a total
of all the warnings, status words or alarms will be
displayed. Warning words, status words and alarm
words can also be read out using the serial bus in
parameters 540, 541 and 538 respectively.
