ADAP-KOOL Drive Programming Guide
WARNING 47, 24 V supply low:
The external 24 V DC backup power supply may be overloaded, otherwise
contact your Danfoss supplier.
ALARM 48, 1.8 V supply low:
Contact your Danfoss supplier.
WARNING 49, Speed limit:
When the speed is not within the specified range in par. 4-11 and par.
4-13. the drive will show a warning. When the speed is below the speci-
fied limit in par. 1-86 (except when starting or stopping) the drive will
trip.
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 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.
WARNING/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 60, External Interlock:
External Interlock has been activated. To resume normal operation, apply
24 VDC to the terminal programmed for External Interlock and reset the
frequency converter (via Bus, Digital I/O or by pressing [Reset]).
WARNING 62, Output Frequency at Maximum Limit:
The output frequency is limited by 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:
Safe Stop has been activated. To resume normal operation, apply 24 VDC
to terminal 37 then send a Reset signal (via Bus, Digital I/O or by pressing
[Reset]).
ALARM 70, Illegal Frequency Converter Configuration:
Actual combination of control board and power board is illegal.
ALARM 80, Drive Initialised to Default Value:
Parameter settings are initialised to default setting after a manual (three-
finger) reset or via par. 14-22.
If the temperature is below 15° C the warning will be present.
WARNING/ALARM 92, NoFlow:
A no load situation has been detected for the system. See parameter
group 22-2*.
WARNING/ALARM 93, Dry Pump:
A no flow situation and high speed indicates that the pump has run dry.
See parameter group 22-2*
WARNING/ALARM 94, End of Curve:
Feed back stays lower than the set point, which may be indicates a leak-
age in the pipe system. See parameter group 22-5*
WARNING/ALARM 95, Broken Belt:
Torque is below the torque level set for no load indicating a broken belt.
See parameter group 22-6*
WARNING 96, Start Delayed:
Start of the motor has been delayed due to short cycle protection is ac-
tive. See parameter group 22-7*.
