It delivers 1.1 kW normal-use output at 3.3 A from a 380-480 V 3-phase supply, with a frequency range of 47.5 to 63 Hz. The drive is rated for heavy-duty use at 0.75 kW / 2.6 A and light-overload use at 1.1 kW / 3.1 A.
The normal-use output current of 3.3 A sets the continuous motor current the drive can deliver without derating. The heavy-duty rating of 2.6 A applies for applications requiring higher torque at low speed or frequent overloads — match this figure to the motor's full-load current if the load profile includes shock or cyclic peaks. Frame size R1 determines the physical footprint for panel layout and mounting.
