ALARM 49, Speed Limit:
When the speed is not within the specified range in
4-11 Motor Speed Low Limit [RPM]
and
4-13 Motor Speed
High Limit [RPM]
, the frequency converter will show a
warning. When the speed is below the specified limit in
1-86 Trip Speed Low [RPM]
(except when starting or
stopping) the frequency converter will trip.
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 presumably 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:
The current is higher than the value in
4-18 Current Limit
.
WARNING 60, External interlock:
External interlock has been activated. To resume normal
operation, apply 24 V DC to the terminal programmed for
external interlock and reset the frequency converter (via
serial communication, digital I/O, or by pressing [Reset]).
WARNING 62, Output Frequency at Maximum Limit:
The output frequency is higher than the value set in
4-19 Max Output Frequency
.
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
22-76 Interval between Starts
.
Warning 97, Stop Delayed:
A stop signal is suppressed because the motor has been
running less time than the minimum time programmed in
22-77 Minimum Run Time
.
Warning 219, Compressor Interlock:
At least one compressor is inversely interlocked via a
digital input. The interlocked compressors can be viewed
in
25-87 Inverse Interlock
.
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
14-23 Typecode Setting
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.
