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 pre-
sumably 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 par. 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 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 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 80° C.
WARNING 66, Heatsink Temperature Low:
The heat sink temperature is measured as 0° C. This could indicate that
the temperature sensor is defective and thus the fan speed is increased
to the maximum in case the power part or 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 normal 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 related information and instructions in the Design Guide
ALARM 70, Illegal Frequency Configuration:
Actual combination of control board and power board is illegal.
ALARM 80, Initialization to Default Value:
Parameter settings are initialised to default setting after a manual (three-
finger) reset.
Warning 96, Start Delayed:
A start signal is suppressed because the time that has passed since last
accepted start is less than the minimum time programmed in par. 22-76.
Warning 97, Stop Delayed:
A stop signal is suppressed because the motor has been running less time
than the minimum time programmed in par. 22-77.
Warning 219, Compressor Interlock:
At least one compressor is inversely interlocked via a digital input. The
interlocked compressors can be viewed in par. 25-87.
ALARM 250, New Spare Part:
The power or Switch Mode Power Supply has been exchanged. The fre-
quency converter type code must be restored in the EEPROM. Select the
correct type code in Par 14-23 according to the label on unit. Remember
to select ‘Save to EEPROM’ to complete.
ALARM 251, New Type Code:
The frequency converter has got a new type code.
