ALARM: 37
Inverter fault (Inverter fault):
IGBT or the power card is defective. Contact your
Danfoss supplier.
Auto-optimisation warnings
Automatic motor adaptation has stopped, since
some parameters have probably been set wrongly,
or the motor used is too big/small for AMA to be car-
ried out. A choice must thus be made by pressing
[CHANGE DATA] and choosing ‘Continue’ + [OK] or
‘Stop’ + [OK].
If parameters need to be changed, select ‘Stop’;
start up AMA all over.
WARNING: 39
CHECK P.104,106
The setting of parameter 102, 104 or 106 is probably
wrong. Check the setting and choose ‘Continue’ or
‘Stop’.
WARNING: 40
CHECK P.103,105
The setting of parameter 102, 103 or 105 is probably
wrong. Check the setting and choose ‘Continue’ or
‘Stop’.
WARNING: 41
MOTOR TOO BIG
The motor used is probably too big for AMA to be
carried out. The setting in parameter 102 may not
match the motor. Check the motor and choose
‘Continue’ or ‘Stop’.
WARNING: 42
MOTOR TOO SMALL
The motor used is probably too small for AMA to be
carried out. The setting in parameter 102 may not
match the motor. Check the motor and choose
‘Continue’ or ‘Stop’.
ALARM: 43
Brake fault (BRAKE FAULT)
A fault has arisen on the brake. The text shown in
the display indicates a fault message. The figure af-
ter the text is the fault code that can be seen in the
fault log, parameter 615.
Brake check failed (BRAKE CHECK FAILED) [0]
The brake check carried out during power-up indi-
cates that the brake has been disconnected. Check
whether the brake has been connected correctly and
that it has not been disconnected.
Brake resistor short-circuited
(BRAKE RESISTOR FAULT) [1]
The brake output has short-circuited. Replace the
brake resistor.
Brake IGBT short-circuited
(BRAKE IGBT FAULT) [2]
The brake IGBT has short-circuited. This fault
means that the unit is not able to stop the brake and
that, consequently, the resistor is constant being en-
ergized.
WARNING/ALARM: 44
Encoder loss (ENCODER FAULT)
The encoder signal is interrupted from terminal 32 or
33. Check the connections.
