Fault/Alarm Description Possible Causes
F003:
Line Undervoltage ■ Actuates when the line voltage remains below the value
defined in P0362 (in percentage of P0296) for a period longer
than the time set in P0357.
( ) = (100% − 0362) × 0296
■ Setting of P0296 in a range above the
rated line voltage.
■ Input fuses open.
■ Loss of a line phase.
F004:
Line Overvoltage ■ Actuates when the line voltage remains above the value
defined in P0361 (in percentage of P0296) for over 5 seconds.
( ) = (100 % + 0361) × 0296
■ Power supply above the maximum value.
■ Setting of P0296 in a range below the
rated line voltage.
F006:
Unbalance of the Line
Voltages ■ Actuates when the difference between the line voltage values
(P0033, P0034 and P0035) remain above the value set in P0363
for over 2 seconds (value of P0363 in percentage of P0296).
(%) =
| 0033
− 0034|
0296
× 100 %
(%) =
| 0034 − 0035|
0296
× 100 %
(%) =
| 0033
− 0035|
0296
× 100 %
■ The line voltage unbalance is above the
setting.
■ System unbalanced.
■ One of the input fuses open.
■ Loss of a line phase.
F008:
Line Under/Over
Frequency
■
Actuates when the line frequency is above or below the
maximum variation set in P0364 (in percentage of the rated
frequency).
. . (
) = (100
% + 0364) × (50 / 60 )
. . (
) = (100
% − 0364) × (50 / 60 )
■
Line frequency above or below the
maximum acceptable variation.
■ One of the input fuses open.
■ Loss of a line phase.
F009:
Field Supply Under/Over
Frequency ■ Actuates when the field supply frequency is above or below
the maximum variation set in P0364 (in percentage of the rated
frequency).
. . ( ) = (100 % + 0364) × (50 / 60 )
. . (
) = (100
% − 0364) × (50 / 60 )
Note: Relevant fault only when the field is supplied externally by
means of connector X3. Otherwise, the field frequency will be the
same as the converter main supply (R/S/T).
■ Field supply frequency above or below
the maximum acceptable variation.
■ One of the field supply fuses open.
F022:
Armature Overvoltage ■ Actuates when the armature voltage exceeds the maximum
level defined by P0358 (in percentage of P0400) for over 2
seconds.
( ) = (100
% + 0358) × 0400
■ Motor is being accelerated by the load.
■ Incorrect value set in P0400.
■ Overvoltage level set too low (P0358).
■ Incorrect field current setting (P0404 and
P0177).
■ Incorrect speed feedback configuration
(tacho / encoder).
A046:
High Load on the Motor ■ Signals when the armature current (P0003) is above the
overload level defined by P0349 (in percentage of P0156).
( ) = 0349
× 0156
Note: This alarm will be active if the following conditions are met:
■ P0156 > P0157 and
■ P0348 = 1 or P0348 = 3.
■ High load on the motor shaft.
■ Rotor locked.
■ Overload level set too low (P0156).
A050:
High Temperature on
Heatsink ■ Signals when the temperature measured on the heatsink is
above 85°C.
Note: The alarm will be removed when the temperature fall
below 82°C.
■ Load requiring a constant current close
to the converter rated capacity.
■ Fault on the fans of product.
■ Improper installation with obstruction of
the inlets and/or outlets of the product.
F051:
Converter
Overtemperature ■ Actuates when the temperature measured on the heatsink
reaches 90°C.
Note: Fault can only be reset when the temperature is below
82°C.
■ Load cycle incompatible with the
converter rated current.
■
Ambient temperature above the
maximum acceptable (40°C).
■ Fault on the fans of product.
■
Improper installation with obstruction of
the inlets and/or outlets of the product.
