VLT Automation Drive FC 300
Operating Instructions High Power
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 and par. 4-13.
ALARM 50, AMA calibration failed:
Contact your Danfoss supplier.
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 big for the AMA to be carried out.
ALARM 55, AMA par. out of range:
The par. 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 time-out:
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:
Contact your Danfoss supplier.
WARNING 61, Encoder loss:
Contact your Danfoss supplier.
WARNING 62, Output Frequency at Maximum Limit:
The output frequency is higher than the value set in par. 4-19
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 cutout temperature of the control
card is 80° C.
WARNING 66, Heatsink Temperature Low:
The heatsink 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 Activated:
Safe Stop has been activated. To resume normal operation, apply 24 V
DC to terminal 37, then send a reset signal (via Bus, Digital I/O, or by
pressing [RESET]). For correct and safe use of the Safe Stop function
follow the related information and instructions in the Design Guide
ALARM 69, Pwr.card temp:
Power card over temperature.
ALARM 70, Illegal FC Configuration:
Actual combination of control board and power board is illegal.
Warning 73, Safe Stop Auto Restart:
Safe Stopped, the drive may autostart when Safe Stop is removed
WARNING 77, Reduced power mode:
This warning indicates that the drive is operating in reduced power mode
(i.e. less than the allowed number of inverter sections). This warning will
be generated on power cycle when the drive is set to run with fewer
inverters and will remain on.
ALARM 79, Illegal PS config:
Current sensor connector at power card not installed or the scaling card
is the incorrect part number or is not installed
ALARM 80, Drive Initialized to Default Value:
Parameter settings are initialized to default setting after a manual (three-
finger) reset.
WARNING 81, CSIV corrupt:
CSIV file has syntax errors.
WARNING 82, CSIV parameter error:
CSIV parameter error
WARNING 85, Dang fail PB:
Profibus/Profisafe Error
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 243, Brake IGBT:
F enclosure equivalent to fault 27 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 244, Heatsink temp:
F enclosure equivalent to fault 29 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 245, Heatsink sensor:
F enclosure equivalent to fault 39 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 246, Pwr. card supply:
F enclosure equivalent to fault 46 in D and E enclosures. Report value
indicates source of the alarm (from left):
0-3 Inverter
4-7 Rectifier
ALARM 247, Pwr. card temp:
F enclosure equivalent to fault 69 in D and E enclosures. Report value
indicates source of the alarm (from left):
