VLT AutomationDrive FC 300 Operating
Instructions
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 61, Tracking Error:
An error between calculated speed and speed measurement from feed-
back device. The function Warning/Alarm/Disabling setting is in par.

ing procedure the function may be effective.
WARNING 62, Output Frequency at Maximum Limit:
The output frequency is higher than the value set in par. 4-19
Frequency
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, then send a reset signal (via Bus, Digital I/O, or by pressing
[RESET]).
WARNING 68, Safe Stop:
Safe Stop has been activated. Normal operation is resumed when Safe
Stop is disabled. Warning: Automatic Restart!
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-

Max Output
MG.33.AC.02 - VLT is a registered Danfoss trademark
tivated. When that happens, a reset signal must be is be sent (via Bus,
Digital I/O, or by pressing [RESET]).
WARNING 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. Warning: Automatic Restart.
ALARM 72, Dangerous Failure:
Safe Stop with Trip Lock. Unexpected signal levels on Safe Stop and Dig-
ital Input from the MCB 112 PTC Thermistor Card.
ALARM 80, Drive Initialised to Default Value:
Parameter settings are initialised to default setting after a manual (three-
finger) reset.
ALARM 90, Encoder loss:
Check the connection to encoder option and eventually replace the MCB
102.
ALARM 91, Analogue Input 54 Wrong Settings:
Switch S202 has to be set in position OFF (voltage input) when a KTY
sensor is connected to analogue input terminal 54.
ALARM 250, New Spare Part:
The power or Switch Mode Power Supply has been exchanged. The fre-
quency converter type code must be restored in the EEPROM. Select the
Typecode Setting
correct type code in par. 14-23
on unit. Remember to select 'Save to EEPROM' to complete.
ALARM 251, New Type Code:
The Frequency Converter has got a new type code.
