Power ratings and duty selection
The 3ABD00048121: Three duty points are listed so the drive can be sized to the load profile without overspending. Normal use (22 kW, 45 A) is the headline figure for typical industrial fans, pumps, and conveyors. Heavy-duty use (18.5 kW, 38 A) applies when the motor demands constant torque across the speed range — mixers, extruders, or positive-displacement pumps. Light-overload use (22 kW, 42.8 A) sits between normal and heavy-duty; it is the same power as normal use but at a slightly lower current, reflecting a different thermal model for variable-torque profiles. The IE2 efficiency class means this drive is matched to older motor fleets or retrofit projects where premium efficiency is not mandated.
Physical and environmental fit
Frame R4 is the mechanical envelope — it defines the module width, depth, and mounting hole pattern for the panel backplate. The WEEE category is 5 (small equipment under 50 cm), which may affect end-of-life reporting in EU jurisdictions.
