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

3072-
5122
Parameter value is outside its limits. Perform an initial-
ization. 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)
.
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, Ground fault 2:
There is a discharge from the output phases to ground, either in the cable
between the adjustable frequency drive and the motor or in the motor
itself.Turn off the adjustable frequency drive and remove the ground
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, 5 V, +/-18 V. 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 AC line voltage, all three
supplied are monitored.
WARNING 47, 24 V supply low:
The external 24 V DC backup power supply may be overloaded, otherwise
contact your Danfoss supplier.
WARNING 48, 1.8 V supply low:
Contact your Danfoss supplier.
WARNING 49, Speed limit:
The speed is not within the specified range in par. 4-11
Motor Speed Low
Limit [RPM]
and par. 4-13
Motor Speed High Limit [RPM]
.
ALARM 50, AMA calibration failed:
The motor is not suitable for the particular size of drive. Start the AMA
procedure once again by par. 1-29
Automatic Motor Adaptation (AMA)
,
eventually with a reduced AMA function. If still failing; check the motor
data.
ALARM 51, AMA check Unom and Inom:
The setting of the motor voltage, motor current, and motor power is pre-
sumably wrong. Make sure the settings.
ALARM 52, AMA low Inom:
The motor current is too low. Check the settings.
ALARM 53, AMA motor too big:
The motor is too big for the AMA to be carried out.
ALARM 54, AMA motor too small:
The motor is too small for the AMA to be carried out.
ALARM 55, AMA par. out of range:
The motor parameter values found from the motor are outside the ac-
ceptable range.
ALARM 56, AMA interrupted by user:
The AMA has been interrupted by the user.
ALARM 57, AMA timeout:
Try to start the AMA again a number of times, until the AMA is carried
out. Please note that repeated runs may heat the motor to a level where
the resistances Rs and Rr are increased. In most cases, however, this is
not critical.
