ALARM 37
Inverter fault (GATE DRIVE FAULT):
An output IGBT or the power card is defective. Contact the Danfoss
Graham service department.
Auto Optimization Warnings 39 through 42
Automatic motor adaptation has stopped, because some parameters
have probably been improperly set, or the motor used in too large or
small for AMA to be carried out.
A choice must be made by pressing CHANGE DATA and choosing
‘Continue’ + OK or ‘Stop’ + OK.
If parameters need to be changed, select ‘Stop’, change the parameters
and run AMA again.
WARNING 39
CHECK PAR. 104, 106
Parameters 104, Motor Frequency, or 106, Rated Motor Speed, have
probably not been set correctly. Correct the setting and run AMA
again.
WARNING 40
CHECK PAR. 103, 105
Parameter 103 Motor Voltage, or 105 Motor Current, has not been set
correctly. Correct the setting and run AMA again.
WARNING 41
Motor Too Large (MOTOR TOO BIG)
The motor used is probably too large for AMA to be carried out. The
setting in parameter 102 Motor Power, may not match the motor. Check
the motor and select ‘Continue’ or [STOP].
WARNING 42
Motor Too Small (MOTOR TOO SMALL)
The motor used is probably too small for AMA to be carried out. The
setting in parameter 102 Motor Power, may not match the motor. Check
the motor and select ‘Continue’ or [STOP].
ALARM 60
Safety Stop (EXTERNAL FAULT)
Terminal 27, parameter 304, Digital Inputs, has been programmed for
a Safety Interlock and is a logic ‘0’.
WARNING 61
Output Frequency Low (FOUT < FLOW)
The output frequency is lower than parameter 223, Warning: Low
Frequency.
WARNING 62
Output Frequency High (FOUT > FHIGH)
The output frequency is higher than parameter 224, Warning: High
Frequency.
WARNING/ALARM 63
Output Current Low (I MOTOR < I LOW)
The output current is lower than parameter 221, Warning: Low
Current. Select the required function in parameter 409, Function in
Case of No Load.
WARNING 64
Output Current High (I MOTOR > I HIGH)
The output current is higher than parameter 222, Warning: High
Current.
WARNING 65
Feedback Low (FEEDBACK < FDB LOW)
The resulting feedback value is lower than parameter 227, Warning:
Low Feedback.
WARNING 66
Feedback High (FEEDBACK > FDB HIGH)
The resulting feedback value is higher than parameter 228, Warning:
High Feedback.
WARNING 67
Remote Reference Low (REF. < REF LOW)
The remote controlled reference is lower than parameter 225,
Warning: Low Reference.
WARNING 68
Remote Reference High (REF. > REF HIGH)
The remote controlled reference is higher than parameter 226,
Warning: High Reference.
WARNING 69
Temperature auto derate (TEMP.AUTO DERATE)
The heat sink temperature has exceeded the maximum value and the
auto derating function in parameter 411 is active. Warning: Temp.auto
Derate.
WARNING 99
Unknown Fault (UNKNOWN ALARM)
An unknown fault has occurred which the software is not able to
handle. Contact Danfoss Graham service department.
