Duty ratings and motor sizing
The 3ABD00059528-D: The normal-duty rating of 22 kW / 40 A is the primary sizing figure for most variable-torque loads such as pumps and fans. For constant-torque applications like conveyors or extruders, the heavy-duty rating of 19 kW / 34 A applies, reflecting the higher thermal stress. The light-overload rating of 22 kW / 38 A covers applications with infrequent overloads.
Frame size and mounting
Frame size R4 defines the mechanical footprint and mounting hole pattern. Wall-mounted installation is standard; the IP21 / NEMA Type 1 enclosure means the drive is not sealed against dust ingress or washdown — locate it in a cabinet or clean electrical room. Verify gland-plate clearance and cable bend radius for the incoming mains and motor leads before committing the panel layout.
