6. Troubleshooting
WARNING 35, Out of frequency range:
This warning is issued if the output frequency
has reached its
Warning speed high
or
justable frequency drive is in
closed-loop (par. 1-00), the warning is active
in the display. If the adjustable frequency
drive is not in this mode, bit 008000

active but there is no warning in the display.
ALARM 38, Internal fault:
Contact the local Danfoss supplier.
WARNING 47, 24 V supply low:
The external 24 V DC back-up power supply
may be overloaded; otherwise, contact your
local Danfoss supplier.
6
WARNING 48, 1.8 V supply low:
Contact the local Danfoss supplier.
ALARM 50, AMA calibration failed:
Contact the local 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 small for the AMA to be car-
ried 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 the local Danfoss supplier.
WARNING 59, Current limit:
Contact the local Danfoss supplier.

WARNING 62, Output Frequency at
Maximum Limit:
The output frequency is higher than the value
set in par. 4-19.
,
WARNING 64, Voltage Limit:
The load and speed combinations demand a
motor voltage higher than the actual DC link
voltage.
WARNING/ALARM/TRIP
Card Overtemperature:
Control card overtemperature: The cut-out
temperature of the control card is 176° F [80°
C].
WARNING 66, Heatsink Temperature
Low:
The heatsink temperature is measured as 32°
F [0° C]. This could indicate that the temper-
ature sensor is defective and thus the fan
speed is increased to the maximum if the pow-
er part or the control card is very hot.
ALARM 67, Option Configuration has
Changed:
One or more options has either been added or
removed since the last power-down.
ALARM 68, Safe Stop Activated:
Safe Stop has been activated. To resume nor-
mal operation, apply 24 V DC to terminal 37,
then send a reset signal (via bus, digital I/O,
or by pressing [RESET]). For correct and safe
use of the Safe Stop function, follow the rela-
ted information and instructions in the Design
Guide
ALARM 70, Illegal Frequency Configura-
tion:
Current combination of control board and
power board is illegal.
ALARM 80, Initialization to Default Val-
ue:
Parameter settings are initialized to default
setting after a manual (three-finger) reset.
