Product Description:
The MIV0204A-1-B5 inverter unit is produced by Okuma within the MIV Servo Drives series. This module functions as a compact drive interface that converts the supply bus into regulated power for synchronous or induction servomotors in CNC machinery. It connects directly to the machine control and distributes power to both the L and M servo channels, providing coordinated motion for tool turrets, feed axes, or auxiliary spindles in automated production lines. The arrangement allows one compact module to serve paired machine motions that must respond to the same control platform.
Internally the unit supports 2-axis operation, meaning a single housing contains independent L-side and M-side stages that run two motors simultaneously. Its logic circuits draw 24 VDC control power, keeping the signal electronics isolated from the main bus. The converter is fed by a 300 VDC link, and this common DC bus lets multiple inverters share regenerated energy while simplifying cabinet wiring. On the L side, continuous output is 2.0 kW, or 2.67 hp, so medium-frame motors can accelerate without derating. The M side provides 4.0 kW, covering axes or spindle loads that demand higher torque. This layout is useful when one channel drives a feed axis and the other drives a heavier rotary load.
Command processing is carried out by the ICB1 control board, and motion algorithms run on ICB-H for position loop updates compatible with BL Motor and PREX Motor feedback. Separate control hardware and power conversion stages help keep command handling and motor output coordinated inside one enclosure. A slim enclosure only 60 mm wide, 295 mm deep, and 380 mm high makes panel layout straightforward during retrofits. The metallic frame weighs 5.5 kg, which helps keep handling manageable during installation with the M4 screws specified for the XT2 terminal strip. As an inverter unit, its DC bus interface forwards regenerated energy to upstream supplies, reducing heat in the cabinet. The second-generation design also standardizes diagnostics across the MIV Servo Drives series, so status reporting remains consistent with related modules in the same platform.
