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
the short circuit connection. Check
5-32 Term X30/6 Digi
Out (MCB 101)
.
For X30/7, check the load connected to X30/7 or remove
the short-circuit connection. Check
5-33 Term X30/7 Digi
Out (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 on the power card is out of range.
There are 3 supplies generated by the switch mode supply
(SMPS) on the power card:
•
24 V.
•
5 V.
•
±
18 V.
When powered with 24 V DC with the MCB 107 option,
only the 24 V and 5 V supplies are monitored. When
powered with 3-phase mains voltage, all 3 supplies are
monitored.
Troubleshooting
•
Check for a defective power card.
•
Check for a defective control card.
•
Check for a defective option card.
•
If a 24 V DC supply is used, verify proper supply
power.
WARNING 47, 24 V supply low
The supply on the power card is out of range.
There are 3 supplies generated by the switch mode supply
(SMPS) on the power card:
•
24 V.
•
5 V.
•
±
18 V.
Troubleshooting
•
Check for a defective power card.
WARNING 48, 1.8 V supply low
The 1.8 V DC supply used on the control card is outside of
the allowable limits. The supply is measured on the control
card. Check for a defective control card. If an option card is
present, check for overvoltage.
WARNING 49, Speed limit
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]
, the frequency
converter shows a warning. When the speed is below the
specified limit in
parameter 1-86 Trip Speed Low [RPM]
(except when starting or stopping), the frequency
converter trips.
ALARM 50, AMA calibration failed
Contact the Danfoss supplier or Danfoss Service.
ALARM 51, AMA check U
nom
and I
nom
The settings for motor voltage, motor current, and motor
power are wrong. Check the settings in
parameters
1–20
to
1–25
.
ALARM 52, AMA low I
nom
The motor current is too low. Check the settings in
.
ALARM 53, AMA motor too big
The motor is too big 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 parameter values of the motor are outside of the
acceptable range. AMA cannot run.
ALARM 56, AMA interrupted by user
The user has interrupted AMA.
ALARM 57, AMA internal fault
Try to restart AMA. Repeated restarts can overheat the
motor.
ALARM 58, AMA Internal fault
Contact the Danfoss supplier.
WARNING 59, Current limit
The current is higher than the value in
. Ensure that motor data in
parameters
1–20
to
1–25
are set correctly. Increase the
current limit if necessary. Ensure that the system can
operate safely at a higher limit.
WARNING 60, External interlock
A digital input signal is indicating a fault condition external
to the frequency converter. An external interlock has
commanded the frequency converter to trip. Clear the
external fault condition. To resume normal operation, apply
24 V DC to the terminal programmed for external interlock.
Reset the frequency converter.
WARNING 62, Output frequency at maximum limit
The output frequency has reached the value set in
parameter 4-19 Max Output Frequency
. Check the
application for possible causes. Possibly increase the
output frequency limit. Be sure that the system can
operate safely at a higher output frequency. The warning
clears when the output drops below the maximum limit.
WARNING/ALARM 65, Control card over temperature
The cut-out temperature of the control card is 80
°
C.
