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 connection. 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 connection. 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 supplied are monitored.
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card. The external V
DC backup power supply may be overloaded, otherwise
contact your Danfoss supplier.
WARNING 48, 1.8 V supply low
The 1.8 V 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
When the speed is not within the specified range in par. 4-11
and par. 4-13. the drive will show a warning. When the speed
is below the specified limit in par. 1-86 Trip Speed Low [RPM]
(except when starting or stopping) the drive will trip.
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 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 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 V DC 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 62, Output frequency at maximum limit
The output frequency is higher than the value set in
par. 4-19 Max Output Frequency
