Diagnostics and Troubleshoo...
•
Check the operation of the communication
equipment.
•
Verify a proper installation based on EMC
requirements.
ALARM 30, Motor phase U missing
Motor phase U between the frequency converter and the
motor is missing.
Remove power from the frequency converter and check
motor phase U.
ALARM 31, Motor phase V missing
Motor phase V between the frequency converter and the
motor is missing.
Remove power from the frequency converter and check
motor phase V.
ALARM 32, Motor phase W missing
Motor phase W between the frequency converter and the
motor is missing.
Remove power from the frequency converter and check
motor phase W.
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
Table 5.6 is displayed.
Troubleshooting
•

WARNING 40, Overload of digital output terminal 27
Check the load connected to terminal 27 or remove short-
circuit connection. Check 5-00 Digital I/O Mode and
5-01 Terminal 27 Mode.
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.
ALARM 44, Earth fault DESAT
There is a discharge from the output phases to earth,
either in the cable between the frequency converter and
the motor, or in the motor itself.
Troubleshooting
•
Turn off the frequency converter and remove the
earth fault.
•
Measure the resistance to ground of the motor
leads and the motor with a megohmmeter to
check for earth fault in the motor.
ALARM 46, Gate drive voltage fault
The supply on the power card is out of range.
There are 3 power supplies generated by the switch mode
power supply (SMPS) on the power card: 24 V, 5 V, and
±18 V.
Troubleshooting
•
Check for a defective power card.
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card. This alarm
arises when the detected voltage of terminal 12 is lower
than 18 V.
Troubleshooting
•
Check for a defective control card.
ALARM 51, AMA check U
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.
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.
Troubleshooting
Contact the supplier or
Danfoss Service
Department.
