VLT AutomationDrive FC 300 Operating
Instructions
WARNING 42, Overload of Digital Output On X30/7 :
Check the load connected to X30/7 or remove short-circuit connection.
Check par. 5-33 Term X30/7 Digi Out (MCB 101)
ALARM 45, Earth fault 2:
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 it-
self.Turn off the frequency converter and remove the earth fault. This
alarm is detected under the start-up test sequence.
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, 5V, +/- 18V. 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 mains voltage, all three sup-
plied are monitored.
WARNING 47, 24 V supply low:
The external 24 V DC backup power supply may be overloaded, otherwise
Contact your Danfoss supplier.
WARNING 48, 1.8 V supply low:
Contact your Danfoss supplier.
WARNING 49, Speed limit:
The speed is not within the specified range in par. 4-11
Limit [RPM] Motor Speed High Limit [RPM]
and par. 4-13
ALARM 50, AMA calibration failed:
The motor is not suitable for the particular size of drive. Start the AMA
procedure once again by par. 1-29
eventually with a reduced AMA function. If still failing; check the motor
data.
ALARM 51, AMA check Unom and Inom:
The setting of motor voltage, motor current, and motor power is pre-
sumably wrong. Check the settings.
ALARM 52, AMA low Inom:
The motor current is too low. Check the settings.
ALARM 53, AMA motor too big:
The motor is too big for the AMA to be carried out.
ALARM 54, AMA motor too small:
The motor is too small for the AMA to be carried out.
ALARM 55, AMA par. out of range:
The motor parameter values found from the motor are outside acceptable
range.
ALARM 56, AMA interrupted by user:
The AMA has been interrupted by the user.
ALARM 57, AMA timeout:
Try to start the AMA again a number of times, until the AMA is carried
out. Please note that repeated runs may heat the motor to a level where
the resistance Rs and Rr are increased. In most cases, however, this is
not critical.
ALARM 58, AMA internal fault:
Contact your Danfoss supplier.
WARNING 59, Current limit:
The current is higher than the value in par. 4-18

WARNING 60, External interlock
External interlock has been activated. To resume normal operation, apply
24 V DC to the terminal programmed for external interlock and reset the
frequency converter (via serial communication, digital I/O, or by pressing
reset button on keypad).
WARNING/ALARM 61, Feedback Error:
An error between calculated speed and speed measurement from feed-
back device. The function Warning/Alarm/Disabling setting is in

WARNING 62, Output Frequency at Maximum Limit:
The output frequency is higher than the value set in par. 4-19
Frequency
. This is a warning in VVC plus
mode.
ALARM 63, Mechanical Brake Low:
The actual motor current has not exceeded the "release brake" current
within the "Start delay" time window.
WARNING 64, Voltage Limit:
The load and speed combination demands a motor voltage higher than
the actual DC link voltage.
WARNING/ALARM/TRIP 65, Control Card Over Temperature:
Control card over temperature: The cut-out temperature of the control
card is 80° C.
WARNING 66, Heatsink Temperature Low:
The heat sink temperature is measured as 0° C. This could indicate that
the temperature sensor is defect and thus the fan speed is increased to
the maximum in case the power part or control card is very hot.
ALARM 67, Option Configuration has Changed:
One or more options has either been added or removed since the last
power down.
ALARM 68, Safe Stop:
Safe Stop has been activated. To resume normal operation, apply 24 V
DC to T-37. Press reset button on LCP.
WARNING 68, Safe Stop:
Safe Stop has been activated. Normal operation is resumed when Safe
Stop is disabled. Warning: Automatic Restart!
ALARM 69, Power card temperature
The temperature sensor on the power card is either too hot or too cold.
Troubleshooting:
Check the operation of the door fans.
Check that the filters for the door fans are not blocked.
Check that the gland plate is properly installed on IP 21 and IP
54 (NEMA 1 and NEMA 12) drives.
ALARM 70, Illegal FC Configuration:
Actual combination of control board and power board is illegal.
ALARM 71, PTC 1 Safe Stop:
Safe Stop has been activated from the MCB 112 PTC Thermistor Card
(motor too warm). Normal operation can be resumed when the MCB 112
applies 24 V DC to T-37 again (when the motor temperature reaches an
acceptable level) and when the Digital Input from the MCB 112 is deac-
tivated. When that happens, a reset signal must be is be sent (via Bus,
Digital I/O, or by pressing [RESET]).
