Product Description:
The MIV30-3-V1 is an inverter unit produced by Okuma as part of the MIV Servo Drives series. It converts shared DC bus energy into controlled three-phase output for multiple servo axes, allowing machine tools to execute coordinated motion profiles without external transformers. Within an automation cell, the unit forms the electrical interface between the CNC controller and the power section, governing acceleration, deceleration, and steady-state speed while protecting connected motors against overload and regenerative surges.
The drive incorporates an ICB3 control board that interprets CNC commands and modulates gate signals. Paired with Control ROM type 1, the board runs vector control algorithms for regulated motor operation. Low-level electronics draw a 24 VDC control supply so the command circuitry stays energized even when the main bus is isolated. Power conversion is fed from a 300 VDC common bus, allowing parallel mounting with other MIV modules that share the same energy reservoir. On its L-side output, the inverter can furnish up to 40 hp, which is equivalent to 30 kW, giving it the capacity to operate multiple medium-frame servomotors or a single high-demand spindle under continuous duty.
The enclosure stands 380 mm high, spans 300 mm wide, and extends 325 mm deep, so a standard 600 mm panel can accommodate front cable loops while maintaining airflow clearance behind the heat sink. Unit mass is 24.0 kg, which supports stable mounting and helps damp vibration transmitted from adjacent modules. The welded chassis aligns with Okuma’s forced-air channel, directing exhaust upward to keep nearby electronics within rated temperatures. This layout also helps maintain consistent thermal behavior in the control section during prolonged operation.
