ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor.
The signal from the IGBT thermal sensor is not available on the power
card. The problem could be on the power card, on the gate drive card,
or the ribbon cable between the power card and gate drive card.
WARNING 40, Overload of Digital Output Terminal 27
Check the load connected to terminal 27 or remove short-circuit connec-
tion. Check par. 5-00
Digital I/O Mode
and par. 5-01
Terminal 27 Mode
.
WARNING 41, Overload of Digital Output Terminal 29
Check the load connected to terminal 29 or remove short-circuit connec-
tion. Check par. 5-00
Digital I/O Mode
and par. 5-02
Terminal 29 Mode
.
WARNING 42, Overload of Digital Output on X30/6 or Overload
of Digital Output on X30/7
For X30/6, check the load connected to X30/6 or remove short-circuit
connection. Check par. 5-32
Term X30/6 Digi Out (MCB 101)
.
For X30/7, check the load connected to X30/7 or remove short-circuit
connection. Check par. 5-33
Term X30/7 Digi Out (MCB 101)
.
ALARM 46, Power card supply
The supply on the power card is out of range.
There are three power supplies generated by the switch mode power
supply (SMPS) on the power card: 24 V, 5V, +/- 18V. When powered with
24 VDC with the MCB 107 option, only the 24 V and 5 V supplies are
monitored. When powered with three phase mains voltage, all three sup-
plied are monitored.
WARNING 47, 24 V supply low
The 24 VDC is measured on the control card. The external 24 VDC backup
power supply may be overloaded, otherwise contact your Danfoss sup-
plier.
WARNING 48, 1.8 V supply low
The 1.8 Volt DC supply used on the control card is outside of allowable
limits. The power supply is measured on the control card.
WARNING 49, Speed limit
The speed is not within the specified range in par. 4-11
Motor Speed Low
Limit [RPM]
and par. 4-13
Motor Speed High Limit [RPM]
.
ALARM 50, AMA calibration failed
Contact your Danfoss supplier.
ALARM 51, AMA check Unom and Inom
The setting of motor voltage, motor current, and motor power is pre-
sumably 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 big for the AMA to be carried out.
ALARM 55, AMA parameter 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. 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
The current is higher than the value in par. 4-18,
Current Limit
.
WARNING 60, External interlock
External interlock has been activated. To resume normal operation, apply
24 VDC to the terminal programmed for external interlock and reset the
frequency converter (via serial communication, digital I/O, or by pressing
reset button on keypad).
WARNING 61, Tracking error
An error has been detected between calculated motor speed and speed
measurement from feedback device. The function for Warning/Alarm/
Disable is set in par 4-30,
Motor Feedback Loss Function
, error setting in
par 4-31,
Motor Feedback Speed Error
, and the allowed error time in par
4-32,
Motor Feedback Loss Timeout
. During a commissioning procedure
the function may be effective.
WARNING 62, Output frequency at maximum limit
The output frequency is higher than the value set in par. 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.
