Warning: There is a risk of substantial power being
transmitted to the brake resistor if the brake transistor
is short-circuited.
WARNING/ALARM 28, Brake check failed:
Brake resistor fault: the brake resistor is not connected/working.
ALARM 29, Drive over temperature:
If the enclosure is IP 20 or IP 21/Type 1, the cut-out temperature of the
heat-sink is 95
º
C +5
º
C. The temperature fault cannot be reset, until the
temperature of the heatsink is below 70
º
C +5
º
C.
The fault could be:
- Ambient temperature too high
- Too long motor cable
ALARM 30, Motor phase U missing:
Motor phase U between the frequency converter and the the motor is
missing.
Turn off the frequency converter and check motor phase U.
ALARM 31, Motor phase V missing:
Motor phase V between the frequency converter and the motor is missing.
Turn off the frequency converter and check motor phase V.
ALARM 32, Motor phase W missing:
Motor phase W between the frequency converter and the motor is miss-
ing.
Turn off the frequency converter and check motor phase W.
ALARM 33, Inrush fault:
Too many power ups have occured within a short time period. See the
chapter
General Specifications
for the allowed number of power ups with-
in one minute.
WARNING/ALARM 34, Fieldbus communication fault:
The fieldbus on the communication option card is not working correctly.
Please check parameters associated with the module and make sure
module is properly inserted in Slot A of the drive. Check the wiring for
fieldbus.
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 frequency 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 com-
mand 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
2821 Serial port overflow
2822 USB port overflow
3072-
5122
Parameter value is outside its limits. Perform a initiali-
zation. Parameter number causing the alarm: Subtract
the code from 3072. Ex Error code 3238: 3238-3072 =
166 is outside the limit
5123 Option in slot A: Hardware incompatible with Control
board hardware
5124 Option in slot B: Hardware incompatible with Control
board hardware
5125 Option in slot C0: Hardware incompatible with Control
board hardware
5126 Option in slot C1: Hardware incompatible with Control
board hardware

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 connec-
tion. 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 connec-
tion. 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)
