WARNING 40, Overload of Digital Out-
put Terminal 27
Check the load connected to terminal 27 or
remove short-circuit connection. Check pa-
rameters 5-00 and 5-01.
WARNING 41, Overload of Digital Out-
10
put Terminal 29:
Check the load connected to terminal 29 or
remove short-circuit connection. Check pa-
rameters 5-00 and 5-02.
WARNING 42, Overload of Digital Out-
put On X30/6:
Check the load connected to X30/6 or remove
short-circuit connection. Check parameter
5-32.
WARNING 42, Overload of Digital Out-
put On X30/7:
Check the load connected to X30/7 or remove
short-circuit connection. Check parameter
5-33.
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:
194
Parameter value is outside its lim-
its. Perform an initialization. Pa-
rameter number causing the
alarm: Subtract the code from

3238-3072 = 166 is outside the
limit

MG.33.B9.22 - VLT
The speed is not within the range specified in
par. 4-11 and par. 4-13.
ALARM 50, AMA calibration failed:
Contact your Danfoss supplier.
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 set-
tings.
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 big for the AMA to be carried
out.
ALARM 55, AMA par. out of range:
The par. values found from the motor are out-
side the 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 it is carried out. Please note that repea-
ted runs may heat the motor to a level where
the resistances 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 par.
4-18.
WARNING 61, Tracking Error:
An error between the calculated speed and
speed measurement from the feedback de-
vice. The function Warning/Alarm/Disabling
setting is in par 4-30. Accepted error setting
in par 4-31 and the allowed time the error oc-
cur setting in par 4-32. During a commission-
ing procedure the function may be effective.
WARNING 62, Output Frequency at
Maximum Limit:
The output frequency is higher than the value
set in par. 4-19.
