FC 300 Design Guide
WARNING/ALARM 34
Fieldbus communication fault:
The fieldbus on the communication option
card is not working.
WARNING 35
Out of frequency range:
This warning is active if the output frequency has
reached its Warning speed low (par. 4-52) or
Warning speed high (par. 4-53). If the adjustable
frequency drive is in Process control, closed loop
(par. 1-00), the warning is active in the display. If
the adjustable frequency drive is not in this mode, bit
008000 Out of frequency range in extended status
word is active but there is no warning in the display.
ALARM 38
Internal fault:
Contact your Danfoss supplier.
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:
Contact your Danfoss supplier.
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 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.

Troubleshooting
ALARM 55
AMA par. out of range:
The par. values found from the motor are
outside 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 the AMA is carried out. Please note that
repeated runs may heat the motor to a level where
the resistance Rs and Rr is increased. In most
cases, however, this is not critical.
ALARM 58
AMA internal fault:
Contact your Danfoss supplier.
WARNING 59
Current limit:
Contact your Danfoss supplier.
WARNING 61
Encoder loss:
Contact your Danfoss supplier.
WARNING 62
Output Frequency at Maximum Limit:
The output frequency is higher than the
value set in par. 4-19
ALARM 63
Mechanical Brake Low:
The actual motor current has not exceeded
the "release brake" current within the "Start
delay" time window.
WARNING 64
Voltage Limit:
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
WARNING/ALARM/TRIP 65
Control Card Over Temperature:
Control card over temperature: The cut-out
temperature of the control card is 176 °F (80 °C).
WARNING 66
Heatsink Temperature Low:
The heat sink temperature is measured as 0° C. This
could indicate that the temperature sensor is defect
