WARNING 41, Overload of digital output terminal 29
Check the load connected to terminal 29 or remove short-
circuit connection. Check
5-00 Digital I/O Mode
and
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
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
5-33 Term X30/7 Digi Out
(MCB 101)
.
ALARM 43, Ext. supply
MCB 113 Ext. Relay Option is mounted without ext. 24V DC.
Either connect an ext. 24V DC supply or specify that no
external supply is used via
14-80 Option Supplied by External
24VDC
[0]. A change in
14-80 Option Supplied by External
24VDC
requires a power cycle.
ALARM 45, Earth fault 2
Earth (ground) fault on start up.
Troubleshooting
Check for proper earthing (grounding) and loose
connections.
Check for proper wire size.
Check 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 three power supplies generated by the switch
mode power supply (SMPS) on the power card: 24V, 5V, +/-
18V. When powered with 24V DC with the MCB 107 option,
only the 24V and 5V supplies are monitored. When powered
with three phase mains voltage, all three supplied are
monitored.
Troubleshooting
Check for a defective power card.
Check for a defective control card.
Check for a defective option card.
If a 24V DC power supply is used, verify proper
supply power.
WARNING 47, 24V supply low
The 24 V DC is measured on the control card. The external
24V DC backup power supply may be overloaded, otherwise
contact your Danfoss supplier.
WARNING 48, 1.8V supply low
The 1.8V DC supply used on the control card is outside of
allowable limits. The power supply is measured on the
control card. Check for a defective control card. If an option
card is present, check for an overvoltage condition.
WARNING 49, Speed limit
When the speed is not within the specified range in
4-11 Motor Speed Low Limit [RPM]
and
4-13 Motor Speed High
Limit [RPM]
, the frequency converter will show 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 will trip.
ALARM 50, AMA calibration failed
Contact yourDanfoss supplier or DanfossService Department.
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 setting 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. AMAwill not run.
ALARM 56, AMA interrupted by user
The AMA has been interrupted by the user.
ALARM 57, AMA timeout
Try to restart AMA again. Repeated restarts may over heat
the motor.
ALARM 58, AMA internal fault
Contact your 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 through 1-25 are
set correctly. Possibly increase the current limit. Be sure the
system can operate safely at a higher limit.
ALARM 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
24V 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
4-30 Motor Feedback Loss Function
.
Accepted error setting in
4-31 Motor Feedback Speed Error
and the allowed time the error occur setting in
4-32 Motor
Feedback Loss Timeout
. During a commissioning procedure
the function may be effective.
