Performance
Use Heavy Duty Rating for applications requiring a high
Application overload tolerance with constant load torque, such as
extruders and conveyors.

Note: Changing the Duty Mode selection automatically changes the maximum size motor that the drive can run, sets the E2-oo parameters to
appropriate values (E4-oo for motor 2), and recalculates parameter settings determined by motor capacity (e.g., b8-04, L2-03).
n C6-02: Carrier Frequency Selection
Sets the switching frequency of the drive output transistors. Changes to the switching frequency lower audible noise and reduce
leakage current.

Use Normal Duty Rating for applications in which the torque
requirements drop along with the speed, such as fans and
pumps where a high overload tolerance is not required.
