Product Description:
The MIV0101-1-B3 is an inverter unit manufactured by Okuma and positioned within the MIV Servo Drives series for multi-axis machine-tool automation. As a dedicated servo drive component, it converts DC bus power into controlled three-phase output for each connected axis, allowing precise speed and torque regulation of synchronous and induction motors used on CNC lathes, mills, and grinders. The drive is divided internally into two power channels labeled L and M, and each channel is governed by an insulated-gate bipolar transistor bridge referenced to the centralized DC link. This arrangement supports paired servo axes in machine tools where coordinated motion and repeatable current control are required across feed and positioning functions.
For signal processing, this unit uses the Okuma proprietary control platform and is fitted with an MIV Servo Drives back-plane interface; the modulation logic resides on the plug-in control board designated ICB1. Motor compatibility is limited to Okuma’s low-inertia BL motor line and the high-efficiency PREX motor series, so parameter tables and current limits are matched to those windings. The rated continuous output per channel is 0.75 ARMS at 200 VAC, while overload response is handled through cycle-by-cycle current limiting to help prevent oversaturation of the stator iron and demagnetization of permanent magnets. Separating the control board from the power stage keeps signal handling and power conversion organized within the unit.
The symmetrical structure means both channels share identical mechanical ratings, and the maximum continuous mechanical output per phase is 1.33 hp, which is equivalent to 1.0 kW. The designation L side refers to the first axis connector block on the left of the heat sink, whereas the M side connector is positioned immediately to its right. Integrated thermistors in each power module track junction temperature to coordinate fan speed and reduce carrier frequency when ambient levels exceed 45 °C. Because the unit controls individual axes independently, both channels can use identical wiring harnesses while maintaining consistent dynamic response during simultaneous interpolation. The channel layout also keeps terminal identification clear when both axes are wired in the same cabinet.
