The order code 3BBR50000418077 corresponds to an ACQ580-01-213A-2 drive in Frame Size R7.
What the frame size means for fit
Frame Size R7 is the mounting and power-stage class for this drive. It determines the gland-plate opening, the DIN-rail or backplate bolt pattern, and the cable bend-radius clearance you need in the panel. If you're swapping an existing R7-frame unit, this order code drops in on the same footprint. If you're designing fresh, the R7 frame dimensions govern the enclosure fill factor and the heat dissipation budget — the drive's rated output is what the frame was built to handle.
