2.1.1.1 DRIVE CURRENT OVERLOAD SELECTION
Four types of drive overload can be set on C56

NB: the choice also changes the rated drive current as shown by the tables in the installation file and
the correct value is always displayed in ampere rms in P53.
The delivered current is also used to calculate the operating temperature reached by the power
component junctions with the drive presumed to be working with standard ventilation at the maximum
ambient temperature permitted.
If this temperature reaches the maximum value permitted for the junctions, the delivered power limit
is restricted to a value that is just over the rated drive current, i.e. the system's effective thermal
current (see following table).
Now the drive will only overload if the temperature drops below the rated value, which will only occur
after a period of operation at currents below the rated current.
The junction temperature calculation also considers the temperature increase that occurs while
operating at low frequencies (below 2.5 Hz) due to the fact that the current is sinusoidal and thus has
peak values that are higher than the average value. With electrical operating frequencies lower than
2.5Hz, the drive goes into maximum overload for 20-30ms after which the maximum current limit is
reduced by √2 as shown by the following table:
C56 Max. drive current
0 120% I NOM AZ for 30 seconds
1 150% I NOM AZ for 30 seconds
2 200% I NOM AZ for 30 seconds
200% I NOM AZ for 3 seconds
3‫٭‬
155% I NOM AZ for 30 seconds
N.B. = the overload time illustrated is calculated with the drive running steady at the rated motor
current. If the average delivered current is lower than the rated motor current, then the overload time
will increase. Thus the overload will be available for a longer or identical time to the ones shown.
N.B. 3‫ = ٭‬the 200% overload is available until junction temperatures are estimated to be 95% of the
rated value; at the rated value the maximum limit becomes 180%. For repeated work cycles, TDE
MACNO is available to estimate the drive's actual overload capacity
