6. Warnings and Alarms
WARNING 42, Overload of Digital Out-
put On X30/7 :
Check the load connected to X30/7 or remove
short-circuit connection. Check parameter
5-33.
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:
The speed is not within the specified range in
par. 4-11 and par. 4-13.
ALARM 50, AMA calibration failed:
6
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 set-
tings.
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 big for the AMA to be carried
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 time-out:
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 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
130
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 cutout
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 defect and thus the fan speed is in-
creased 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
ALARM 70, Illegal FC Configuration:
Actual combination of control board and pow-
er board is illegal.
ALARM 80, Drive Initialized to Default
Value:
Parameter settings are initialized to default
setting after a manual (three-finger) reset.
ALARM 91, Analogue Input 54 Wrong
Settings:
Switch S202 has to be set in position OFF
(voltage input) when a KTY sensor is connec-
ted to analogue input terminal 54.
ALARM 250, New Spare Part:
The power or Switch Mode Power Supply has
been exchanged. The frequency converter
type code must be restored in the EEPROM.
Select the correct type code in Par 14-23 ac-
cording 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.
