The par. values found from the motor are out-
side 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:
6
The current is higher than the value in par.
4-18.
WARNING 62, Output Frequency at
Maximum Limit:
The output frequency is limited by 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
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 70, Illegal Frequency Configura-
tion:
