Danfoss VLT AutomationDrive FC 300 Instruction Manual

Please confirm the spare part and its power card are the correct part
number.
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 78, Tracking Error:
The difference between setpoint value and actual value has exceeded the
value in par. 4-35
Tracking Error . Disable the function by
par. 4-34
Tracking Error Function or select an alarm/warning also in
par. 4-34
Tracking Error Function . Investigate the mechanics around the
load and motor. Check feedback connections from motor – encoder – to
drive. Select motor feedback function in par. 4-30
Motor Feedback Loss
Function
. Adjust tracking error band in par. 4-35 Tracking Error and
par. 4-37
Tracking Error Ramping .
ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not installed. Also MK102
connector on the power card could not be installed.
ALARM 80, Drive Initialized to Default Value:
Parameter settings are initialized to default setting after a manual (three-
finger) reset.
ALARM 81, CSIV corrupt:
CSIV file has syntax errors.
ALARM 82, CSIV par. err.:
CSIV failed to init a parameter.
ALARM 85, Dang fail PB:
Profibus/Profisafe Error.
ALARM 86, Dang fail DI:
Sensor Error.
ALARM 90, Feedback Mon.:
Check the connection to encoder/ resolver option and eventually replace
the MCB 102or MCB 103.
ALARM 91, Analog Input 54 Wrong Settings:
Switch S202 has to be set in position OFF (voltage input) when a KTY
sensor is connected to analog input terminal 54.
ALARM 243, Brake IGBT
This alarm is only for F Frame drives. It is equivalent to Alarm 27. The
report value in the alarm log indicates which power module generated
the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 244, Heatsink temperature
This alarm is only for F Frame drives. It is equivalent to Alarm 29. The
report value in the alarm log indicates which power module generated
the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 245, Heatsink sensor
This alarm is only for F Frame drives. It is equivalent to Alarm 39. The
report value in the alarm log indicates which power module generated
the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
ALARM 246, Power card supply
This alarm is only for F Frame drives. It is equivalent to Alarm 46. The
report value in the alarm log indicates which power module generated
the alarm:
1 = left most inverter module.
2 = middle inverter module in F2 or F4 drive.
2 = right inverter module in F1 or F3 drive.
3 = right inverter module in F2 or F4 drive.
5 = rectifier module.
