Troubleshooting
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 parameter 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 parameter 5-33 Term
X30/7 Digi Out (MCB 101).
ALARM 43, Ext. supply
MCB 113 Ext. Relay Option is mounted without external 24
V DC. Either connect an ext. 24 V DC supply or specify that
no external supply is used via parameter 14-80 Option
Supplied by External 24VDC [0] No. A change in
parameter 14-80 Option Supplied by External 24VDC requires
a power cycle.
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 24 V DC is measured on the control card. This alarm
appears when the detected voltage of terminal 12 is <18
V.
Troubleshooting
•
Check for a defective control 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.

Programming Guide
WARNING 49, Speed limit
When the speed is outside of the specified range in
4-11 Motor Speed Low Limit [RPM] and 4-13 Motor Speed
High Limit [RPM], the frequency converter shows a warning.
When the speed is below the specified limit in 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
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
The motor current is too low. Check the settings in
4-18 Current Limit.
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 again. Repeated restarts can over heat
the motor.
ALARM 58, AMA Internal fault
Contact the Danfoss supplier.
WARNING 59, Current limit
The current is higher than the value in 4-18 Current Limit.
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/ALARM 61, Feedback error
An error between calculated speed and speed
measurement from feedback device. The function Warning/
Alarm/Disabling setting is in parameter 4-30 Motor
Feedback Loss Function. The tolerable error is set in
parameter 4-31 Motor Feedback Speed Error. The tolerable
feedback loss time is set in parameter 4-32 Motor Feedback
Loss Timeout. During a commissioning procedure the
function may be effective.
