3072- Parameter value is outside its limits. Perform an initiali-
5122 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
5376- Out of memory

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.

Operating Guide
WARNING 40, Overload of Digital Output Terminal 27
Check the load connected to terminal 27 or remove short-
circuit connection. Check parameter 5-00 Digital I/O Mode
and parameter 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 parameter 5-00 Digital I/O Mode
and parameter 5-02 Terminal 29 Mode.
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, 5 V,
+/-18 V. When powered with 24 V DC with the MCB 107
option, only the 24 V and 5 V supplies are monitored.
When powered with three-phase mains voltage, all three
phases 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
parameter 4-11 Motor Speed Low Limit [RPM] and
parameter 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
parameter 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 motor voltage, motor current, and motor
power is presumably wrong. Check 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 large 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 acceptable range.
ALARM 56, AMA interrupted by user
The AMA has been interrupted by the user.
