maximum current reference vector (I
MaxRef
) is equal to 1.1 x
Maximum Rated Current
(11.060) or 0.7 x Kc whichever is lower.
The drive can have a heavy duty rating intended for applications where high overload current may be required under transient conditions, or it can have
a normal duty rating where a lower level of overload current is required. The duty rating is selected automatically by the drive based on the setting of
Rated Current
(05.007). The
Maximum Heavy Duty Rating
(11.032) and
Maximum Rated Current
(11.060) are fixed for each drive size and the table
below shows the possible duty ratings that can be selected depending on the levels of these parameters.
Conditions
Possible duty ratings
Maximum Heavy Duty Rating
(11.032) = 0.00
Normal duty operation only
Maximum Heavy Duty Rating
(11.032) <
Maximum Rated Current
(11.060)
Heavy duty operation if rated current > MAX, otherwise
normal duty operation
Maximum Heavy Duty Rating
(11.032) =
Maximum Rated Current
(11.060)
Heavy duty operation only
The different duty ratings modify the motor protection characteristic (see
Motor Thermal Time Constant 1
(04.015)). The different duty ratings can also
change the level of I
MaxRef
as described previously.
In a drive that contains multiple power modules
Full Scale Current Kc
(11.061) is the full scale current of an individual module multiplied by the number
of modules.
Maximum Heavy Duty Rating
(11.032) and
Maximum Rated Current
(11.060) are the value for an individual module multiplied by the
number of modules.
