Internal fault. Contact the Danfoss supplier or
Danfoss service department.
Table 6.4 Internal Fault Codes
ALARM 39, Heat sink sensor
No feedback from the heat sink 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 gatedrive card, or the ribbon cable between the
power card and gatedrive card.
WARNING 40, Overload of digital output terminal 27
Check the load connected to terminal 27 or remove the
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
Check the load connected to terminal 29 or remove the
short-circuit connection. Also check
parameter 5-00 Digital
I/O Mode
and
parameter 5-02 Terminal 29 Mode
.
WARNING 42, Overload of digital output on X30/6 or
overload of digital output on X30/7
For terminal X30/6, check the load connected to terminal
X30/6 or remove the short-circuit connection. Also check
parameter 5-32 Term X30/6 Digi Out (MCB 101)
(VLT
®
General Purpose I/O MCB 101).
For terminal X30/7, check the load connected to terminal
X30/7 or remove the short-circuit connection. Check
parameter 5-33 Term X30/7 Digi Out (MCB 101)
(VLT
®
General Purpose I/O MCB 101).
ALARM 45, Earth fault 2
Ground fault.
Troubleshooting
•
Check for proper grounding and loose
connections.
•
Check for proper wire size.
•
Check the motor cables for short circuits or
leakage currents.
ALARM 46, Power card supply
The supply for the gate drive on the power card is out of
range.
Troubleshooting
•
Check for a defective power card.
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card.
Troubleshooting
•
Contact the Danfoss supplier or Danfoss service
department.
WARNING 48, 1.2 V supply low
The 1.2 V DC supply used on the control card is outside of
the allowable limits. The supply is measured on the control
card.
Troubleshooting
•
Check for a defective control card.
•
If an option card is present, check for
overvoltage.
WARNING 49, Speed limit
The warning is shown when the speed is outside of the
specified range in
parameter 4-11 Motor Speed Low Limit
[RPM]
and
parameter 4-13 Motor Speed High Limit [RPM]
.
When the speed is below the specified limit in
parameter 1-86 Trip Speed Low [RPM]
(except when starting
or stopping), the drive trips.
ALARM 50, AMA calibration failed
Contact the Danfoss supplier or Danfoss Service
Department.
ALARM 51, AMA check U
nom
and I
nom
The settings for motor voltage, motor current, and motor
power are wrong.
Troubleshooting
•
Check the settings in
parameters 1-20 to 1-25
.
ALARM 52, AMA low I
nom
The motor current is too low.
Troubleshooting
•
Check the settings in
.
ALARM 53, AMA motor too big
The motor is too large for the AMA to operate.
ALARM 54, AMA motor too small
The motor is too small for the AMA to operate.
ALARM 55, AMA parameter out of range
The AMA cannot run because the parameter values of the
motor are outside of the acceptable range.
ALARM 56, AMA interrupted by user
The AMA is manually interrupted.
ALARM 57, AMA internal fault
Try to restart the AMA. Repeated restarts can overheat the
motor.
ALARM 58, AMA Internal fault
Contact the Danfoss supplier.
