Product Description:

The MIV30-3-V5 inverter unit is produced by Okuma within the MIV Servo Drives series. As an Okuma Inverter Unit, it interfaces between the DC bus of an Okuma VAC Motor and the plant’s incoming supply to regulate torque and speed commands in machining centers and other CNC equipment. In industrial automation it converts the constant-voltage DC link into controlled three-phase output so that the attached motor receives the precise amplitude and frequency required for contouring and spindle positioning.

On the power side, the L-axis of this drive can deliver up to 40 hp, which is the mechanical power that can be transferred to the connected axis without overloading the silicon devices. The same capacity is expressed electrically as 30 kW, giving planners a direct comparison with mains ratings and breaker sizes. The internal bus accepts a nominal link voltage of 300 VDC, while a separate control section operates from 24 VDC so encoder power and logic can stay active during main-power dropouts. Cabinet planning is simplified by the unit’s front-panel footprint; its enclosure measures a width of 300 mm, which lets it line up with neighboring servo amplifiers on standard 300-mm DIN shelves.

The remaining dimensions influence airflow and weight distribution in a sealed CNC cabinet. A depth of 325 mm ensures that cable bends remain inside the enclosure without exceeding minimum radius, and a height of 380 mm keeps the heat-sink fins aligned with common cooling-fan arrays. The unit has a shipping and installation mass of 24.0 kg, which affects slide-rail and lift-point selection. The unit is engineered specifically for a VAC Motor interface, so its current regulators, carrier frequencies, and fault diagnostics are matched to the rotor feedback protocols used across Okuma machining platforms.
