Product Description:

The MIV0101A-1-B5 is an Okuma inverter unit from the MIV Servo Drives series. It operates as a dual-axis servo amplifier that supplies regulated power to BL or PREX motors used on CNC machine tools and other automated stations. By converting common DC-link voltage into phase-modulated outputs, the unit helps the motion controller maintain precise speed and position loops. This arrangement allows one compact amplifier to support coordinated motion on paired machine axes. It is suited to applications where synchronized feed motion and stable servo response are required across more than one machine function.

This drive supports 2 axes, each handled through dedicated current loops while command and feedback data move over servo, encoder, and converter links connected to the CNC and power converter. Control electronics are energized from a 24 VDC supply, which keeps the logic section separate from the main bus during line disturbances. The main bus operates at 300 VDC, supplied by the upstream converter and distributed through laminated bars inside the enclosure. Thermal energy created by switching losses is removed by an external fan, allowing steady operation during continuous duty. The module can operate BL or PREX motors on its L and M sides, giving the machine two independently controlled motor channels in one housing.

The aluminum housing measures 60 mm in width, 295 mm in depth, and 380 mm in height, so it fits narrow vertical spaces in electrical panels. With a mass of 5.5 kg, the unit remains manageable during panel mounting and also adds enough rigidity to help limit vibration. Field wiring is landed on M6 terminals at XT1 and M4 screws at XT2, which separates heavier power conductors from smaller connection points. The narrow enclosure also leaves room for adjacent modules and cable routing in compact cabinet layouts. Cable access remains straightforward because the slim profile reduces obstruction around neighboring hardware.
