Troubleshooting
WARNING 40, Overload of Digital Output Terminal 27
Troubleshooting:
•
Check the load connected to terminal 27 or
remove short-circuit connection.
•
Check parameter 5-00 Digital I/O Mode and
parameter 5-01 Terminal 27 Mode.
WARNING 41, Overload of Digital Output Terminal 29
Troubleshooting:
•
Check the load connected to terminal 29 or
remove short-circuit connection.
•
Check parameter 5-00 Digital I/O Mode and
parameter 5-02 Terminal 29 Mode.
WARNING 42, Overload of Digital Output On X30/6
Troubleshooting:
•
Check the load connected to X30/6 or remove
short-circuit connection.
•
Check parameter 5-32 Term X30/6 Digi Out (MCB
101).
WARNING 42, Overload of Digital Output On X30/7
Troubleshooting:
•
Check the load connected to X30/7 or remove
short-circuit connection.
•
Check parameter 5-33 Term X30/7 Digi Out (MCB
101).
WARNING 47, 24 V supply low
The external 24 V DC back-up power supply may be
overloaded, otherwise contact the Danfoss supplier.
ALARM 48, 1.8 V supply low
Contact the Danfoss supplier.
WARNING 49, Speed limit
When the speed is not within the specified range in
parameter 4-11 Motor Speed Low Limit [RPM] and
parameter 4-13 Motor Speed High Limit [RPM], the frequency
converter shows a warning. When the speed is below the
specified limit in parameter 1-86 Compressor Min. Speed for
Trip [RPM] (except when starting or stopping), the
frequency converter trips.
ALARM 50, AMA calibration failed
Contact the Danfoss supplier.
ALARM 51, AMA check U
nom
The setting of motor voltage, motor current, and motor
power is presumably wrong.
Troubleshooting:
•
Check the settings.
ALARM 52, AMA low I
nom
The motor current is too low.
Troubleshooting:
•
Check the settings.
ALARM 53, AMA motor too big
The motor is too big for the AMA to be carried out.

nom

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 parameter 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. Note that repeated runs may heat the
motor to a level where the resistance R
increased. In most cases, however, this is not critical.
WARNING/ALARM 58, AMA internal fault
Contact the Danfoss supplier.
WARNING 59, Current limit
The current is higher than the value in
parameter 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
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
Parameter 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 overtemperature: The cutout temperature of
the control card is 80 °C (176 °F).
WARNING 66, Heatsink Temperature Low
The heat sink temperature is measured as 0 °C (32 °F). This
could indicate that the temperature sensor is defective,
and thus the fan speed is increased to the maximum if 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 Torque Off 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]).
ALARM 70, Illegal Frequency Converter Configuration
Actual combination of control board and power board is
illegal.
ALARM 80, Drive Initialized to Default Value
Parameter settings are initialized to default setting after a
manual (3-finger) reset or via parameter 14-22 Operation
Mode.
