Product Description:

The MIV0102A-1-B5 inverter unit belongs to the MIV Servo Drives series manufactured by Okuma. As a servo drive component, it interfaces between the CNC control and paired synchronous motor channels, providing the regulated power conversion required for precise positioning and feed operations on machine tools and other automated equipment. Its role is to convert direct-current link voltage into controlled three-phase output while coordinating with feedback signals for closed-loop motion control. This arrangement allows one module to support coordinated axis movement without requiring separate inverter sections for each connected motor channel.

Internally, the drive is configured for 2 independent axes. Each axis receives command logic from a 24 VDC control supply that keeps the gate drivers and monitoring circuits active even during main power interruptions. The power stage draws energy from a shared 300 VDC DC bus, which supports rapid current transitions without separate rectifiers for each channel. The left-side power channel is rated at 1.0 kW, making it suitable for lighter motion loads such as auxiliary slides or smaller rotary functions. The main-side channel is rated at 2.0 kW, allowing it to drive heavier linear motion tasks at production speeds while remaining within the same compact housing.

The corresponding mechanical ratings are 1.33 hp on the L side and 2.67 hp on the M side, providing horsepower references for motor matching. Field wiring uses an M4 lower terminal screw for logic connections and an M6 upper terminal screw for the DC bus and motor leads, which keeps low-power and high-current terminations separated by function. The housing weighs 5.5 kg, which keeps the module manageable in standard cabinet installations. Its compact mass also helps limit vibration transfer to adjacent control electronics as the drive modulates energy between channels.
