Product Description:
The MIV15-3-V1 is an inverter unit made by Okuma for the MIV Servo Drives series used in CNC and general automation. It regulates three-phase AC motors by converting shared DC link power into controlled AC output for spindle or feed-axis duty. When connected to an Okuma OSP control, it serves as the power stage that responds to motion commands while monitoring current, temperature, and fault status. Because the inverter modulates motor voltage and frequency in real time, it can follow changing acceleration, deceleration, and steady-state load demands. This makes it suitable for machine functions that require repeatable speed and torque control during cutting and positioning cycles.
The drive is sized for motors up to 15 kW, allowing continuous power delivery for appropriately matched axes. Its power section operates from a 300 VDC bus, while low-voltage logic is supplied separately with 24 VDC so control functions can remain active during a main power interruption. Using a common DC link can simplify multi-axis machine layouts by allowing several inverter sections to draw from the same source. The housing width of 150 mm helps conserve cabinet space and leaves more room for neighboring modules, cable bends, and cooling paths. Even with that narrow face, the complete unit weighs 11.2 kg, so the mounting surface must support the mass of the heat sink, power components, and internal reactors.
The unit has a height of 380 mm and a depth of 325 mm, so enclosure layout must allow enough space for airflow and cable routing. Control functions are managed by the ICB3 inverter control board, which handles pulse-width modulation, overcurrent protection, and parameter retention inside the power section. Operating states and alarm codes are shown on a front-panel 7-segment LED display, allowing status checks directly at the cabinet. The terminal arrangement uses M6 and M8 screws at XT1 and XT2 to secure the main electrical connections. Its AC motor interface also supports proper commutation with compatible Okuma feedback devices.
