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 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:
8
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
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 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
