Danfoss VLT AutomationDrive FC 361 Programming Manual page 191

Troubleshooting
•
Adjust the tracking error band in
parameter 4-35 Tracking Error and
parameter 4-37 Tracking Error Ramping.
ALARM 79, Illegal power section configuration
The scaling card has an incorrect part number or is not
installed. The MK102 connector on the power card could
not be installed.
ALARM 80, Drive initialised to default value
Parameter settings are initialized to default settings after a
manual reset. To clear the alarm, reset the unit.
ALARM 81, CSIV corrupt
CSIV file has syntax errors.
ALARM 82, CSIV parameter error
CSIV failed to initialize a parameter.
ALARM 83, Illegal option combination
The mounted options are incompatible.
ALARM 88, Option detection
A change in the option layout is detected.
Parameter 14-89 Option Detection is set to [0] Frozen config-
uration and the option layout has been changed.
•
To apply the change, enable option layout
changes in parameter 14-89 Option Detection.
•
Alternatively, restore the correct option configu-
ration.
ALARM 90, Feedback monitor
Check the connection to encoder/resolver option and, if
®
necessary, replace VLT Encoder Input MCB 102 or VLT
Resolver Input MCB 103.
ALARM 91, Analog input 54 wrong settings
Set switch S202 in position OFF (voltage input) when a
KTY sensor is connected to analog input terminal 54.
ALARM 95, Broken belt
Torque is below the torque level set for no load, indicating
a broken belt. Parameter 22-60 Broken Belt Function is set
for alarm.
Troubleshooting
•
Troubleshoot the system and reset the frequency
converter after clearing the fault.
ALARM 99, Locked rotor
The rotor is blocked.
WARNING/ALARM 101, Speed monitor
The speed monitor is out of range.
WARNING/ALARM 104, Mixing fan fault
The fan is not operating. The fan monitor checks that the
fan is spinning at power-up or whenever the mixing fan is
turned on. The mixing-fan fault can be configured as a
warning or an alarm trip in parameter 14-53 Fan Monitor.
Troubleshooting
•
Cycle power to the drive to determine if the
warning/alarm returns.

Programming Guide
WARNING/ALARM 122, Mot. rotat. unexp.
The drive performs a function that requires the motor to
be at standstill, for example DC hold for PM motors.
WARNING/ALARM 148, System temp
One or more of the system temperature measurements is
too high.
WARNING/ALARM 154, D.out overload
Digital output overloaded.
ALARM 244, Heat sink temperature
This alarm is equivalent to ALARM 29, Power module temp.
The report value in the alarm log indicates which power
module generated the alarm:
ALARM 245, Heat sink sensor
There is no feedback from the heat sink sensor.
The report value in the alarm log indicates which power
module generated the alarm:
