Troubleshooting
WARNING/ALARM 36, Mains failure:
This warning/alarm is only active if the supply voltage to the
frequency converter is lost and par. 14-10 Mains Failure is NOT
set to OFF. Possible correction: check the fuses to the frequen-
cy converter
ALARM 37, Phase imbalance:
There is a current imbalance between the power units
ALARM 38, Internal fault:
By this alarm it may be necessary to contact your Danfoss
supplier. Some typical alarm messages:
0 The serial port cannot be initialized. Serious hardware
failure
256 The power EEPROM data is defect or too old
512 The control board EEPROM data is defect or too old
513 Communication time out Reading EEPROM data
514 Communication time out Reading EEPROM data
515 The Application Orientated Control cannot recognize the
EEPROM data
516 Cannot write write to the EEPROM because a write
command is on progress
517 The write command is under time out
518 Failure in the EEPROM
519 Missing or invalid BarCode data in EEPROM 1024 – 1279
CAN telegram cannot be sent. (1027 indicate a possible
hardware failure)
1281 Digital Signal Processor flash time-out
1282 Power micro software version mismatch
1283 Power EEPROM data version mismatch
1284 Cannot read Digital Signal Processor software version
1299 Option SW in slot A is too old
1300 Option SW in slot B is too old
1311 Option SW in slot C0 is too old
1312 Option SW in slot C1 is too old
1315 Option SW in slot A is not supported (not allowed)
1316 Option SW in slot B is not supported (not allowed)
1317 Option SW in slot C0 is not supported (not allowed)
1318 Option SW in slot C1 is not supported (not allowed)
1536 An exception in the Application Orientated Control is
registered. Debug information written in LCP
1792 DSP watchdog is active. Debugging of power part data
Motor Orientated Control data not transferred correctly
2049 Power data restarted
2315 Missing SW version from power unit
2816 Stack overflow Control board module
2817 Scheduler slow tasks
2818 Fast tasks
2819 Parameter thread
2820 LCP stack overflow

ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor.
The signal from the IGBT thermal sensor is not available on the
power card. The problem could be on the power card, on the
gate drive card, or the ribbon cable between the power card
and gate drive card.
WARNING 40, Overload of Digital Output Terminal 27
Check the load connected to terminal 27 or remove short-
circuit connection. Check par. 5-00 Digital I/O Mode and
par. 5-01 Terminal 27 Mode.
WARNING 41, Overload of Digital Output Terminal 29:
Check the load connected to terminal 29 or remove short-
circuit connection. Check par. 5-00 Digital I/O Mode and
par. 5-02 Terminal 29 Mode.
WARNING 42, Overload of Digital Output On X30/6 :
Check the load connected to X30/6 or remove short-circuit
connection. Check par. 5-32 Term X30/6 Digi Out (MCB 101).
WARNING 42, Overload of Digital Output On X30/7 :
Check the load connected to X30/7 or remove short-circuit
connection. Check par. 5-33 Term X30/7 Digi Out (MCB 101).
ALARM 45, Earth fault 2:
There is a discharge from the output phases to earth, either in
the cable between the frequency converter and the motor or
in the motor itself.Turn off the frequency converter and
remove the earth fault. This alarm is detected under the start-
up test sequence.
ALARM 46, Power card supply
The supply on the power card is out of range.
There are three power supplies generated by the switch mode
power supply (SMPS) on the power card: 24 V, 5V, +/- 18V.
When powered with 24 VDC with the MCB 107 option, only
the 24 V and 5 V supplies are monitored. When powered with
three phase mains voltage, all three supplied are monitored.
WARNING 47, 24 V supply low:
The external 24 V DC backup power supply may be overloa-
ded, otherwise Contact your Danfoss supplier.
WARNING 48, 1.8 V supply low:
Contact your Danfoss supplier.
