3072- Parameter value is outside its limits. Perform a initiali-
5122 zation. Parameter number causing the alarm: Subtract the
code from 3072. Ex Error code 3238: 3238-3072 = 166 is
outside the limit

A A LARM 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 5-00 Digital I/O Mode and
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 5-00 Digital I/O Mode and
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: 24V, 5V, +/-
18V. When powered with 24V DC with the MCB 107 option,
only the 24V and 5V supplies are monitored. When powered
with three phase mains voltage, all three supplied are
monitored.

VLT Decentral Drive FCD 302 Operating Instructions
WARNING 47, 24V supply low:
The external 24V DC backup power supply may be
overloaded, otherwise Contact your Danfoss supplier.
WARNING 48, 1.8V supply low:
Contact your Danfoss supplier.
WARNING 49, Speed limit:
The speed is not within the specified range in 4-11 Motor
Speed Low Limit [RPM] and 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 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 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 acceptable 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 resistance Rs and Rr are increased.
In most cases, however, this is not critical.
ALARM 58, AMA internal fault:
Contact your Danfoss supplier.
WARNING 59, Current limit:
The current is higher than the value in 4-18 Current Limit.
WARNING 60, External interlock
External interlock has been activated. To resume normal
operation, apply 24V DC to the terminal programmed for
external interlock and reset the frequency converter (via
serial communication, digital I/O, or by pressing reset button
on keypad).
WARNING/ALARM 61, Feedback Error:
An error between calculated speed and speed measurement
from feedback device. The function Warning/Alarm/
Disabling setting is in 4-30 Motor Feedback Loss Function.
Accepted error setting in 4-31 Motor Feedback Speed Error
and the allowed time the error occur setting in 4-32 Motor
Feedback Loss Timeout. During a commissioning procedure
the function may be effective.
