Product Description:
The MIV02-1-B3 inverter unit is manufactured by Okuma as a member of the MIV Servo Drives series. In machine tools, this type of drive helps maintain responsive axis behavior during interpolation, indexing, and rapid positioning moves. This module is intended to run a single servo axis by converting DC bus energy into controlled three-phase output for precision motion in CNC machine tools and other automated stations. Serving as an interface between the power supply and a matched BL motor, it modulates current, monitors feedback, and coordinates torque delivery so that positional commands from the host controller are executed accurately. Its single-axis layout keeps the power stage and control functions focused on one motor channel.
Electrically, the drive’s logic circuitry is powered by a 24 VDC control supply, while the main power stage draws from a 300 VDC bus, keeping high-energy switching separate from low-level command electronics. Separating these supply levels helps reduce the effect of power-stage switching noise on command processing and feedback handling. It supports one axis, and the left-side output channel is rated for 2.0 kW, which corresponds to 2.67 hp. Okuma specifies BL/PREX synchronous motors for this cabinet, and the control section is matched to the electrical constants used by that motor family. This arrangement supports stable torque production, rapid acceleration, and regenerative braking behavior suited to compact lathes, grinders, and auxiliary machine axes.
Mechanical packaging is based on the service board code ICB1, and nonvolatile parameters are stored on control ROM type 3 so operating data remains available after power is removed. Cabinet space requirements are modest because the housing width is 60 mm, the front height is 380 mm, and the depth measures 325 mm. The slender profile allows multiple axes to be installed side by side on a common rail while preserving airflow around the heat sink. The housing proportions also leave room for adjacent wiring ducts and bus connections without making the unit unusually wide for a single-axis cabinet module. Its compact enclosure helps keep multi-axis cabinet layouts orderly where several servo modules share the same panel space.
