Duty ratings — normal vs heavy vs light overload
The 3ABD00046720-D: This drive carries three distinct output ratings, and which one governs your application depends on the load profile. Normal use delivers 3 kW at 7.2 A — that's your baseline for constant torque loads like positive displacement pumps or screw compressors running continuously. Light-overload use sits at 3.0 kW and 6.8 A — essentially the normal duty current derated slightly, likely for variable torque applications like centrifugal pumps and fans where the load drops off at lower speeds. The IE2 efficiency class means it meets the baseline European efficiency standard for motor-drive systems.
