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).
WARNING/ALARM 45, Ground Fault 2
Ground fault on start-up.
Troubleshooting
• Check for proper grounding and loose connections.
• Check for proper wire size.
• Check motor cables for short-circuits or leakage cur-
rents.
WARNING/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, 5 V,
+/- 18 V. 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 AC line 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 24 VDC power supply is used, verify proper sup-
ply power.
WARNING/ALARM 47, 24 V Supply Low
The 24 V DC is measured on the control card. The exter-
nal 24 VDC backup power supply may be overloaded;
otherwise, contact your Danfoss supplier.
WARNING/ALARM 48, 1.8 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 condi-
tion.
WARNING/ALARM 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 adjustable frequency drive 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 adjustable frequency drive will trip.
ALARM 50, AMA calibration failed
Contact your 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. 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. AMA will 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 exter-
nal to the adjustable frequency drive. An external inter-
lock has commanded the adjustable frequency drive to
trip. Clear the external fault condition. To resume normal
operation, apply 24 VDC to the terminal programmed for
external interlock. Reset the adjustable frequency drive.
WARNING 62, Output frequency at maximum limit
The output frequency has reached the value set in 4-19
Max Output Frequency. Check the application to deter-
mine the cause. Possibly increase the output frequency
limit. Be sure the system can operate safely at a higher
output frequency. The warning will clear when the output
drops below the maximum limit.
WARNING/ALARM 65, Control card over temperature
The cutout temperature of the control card is 176°F
[80 °C].
