The physical footprint of the FR-D720-7.5K is highly compact; however, mounting hole dimensions differ from legacy models, making a mounting adapter plate necessary for direct panel replacement.

Under these conditions, specify an inverter-duty motor with independent blower cooling or derate the drive. Note that the internal regenerative braking torque limit is 20%.
