Product Introduction

The Okuma MIV0101A-1-B5 is a dual-axis servo inverter module engineered for Okuma’s MIV CNC machine lineup.It supports both the A-axis and B-axis with 1.0 kW each,delivering balanced and coordinated motion control.The built-in ICB2 controller board(with Type 5 firmware)handles encoder feedback,position synchronization,and torque monitoring—all within its compact chassis.This makes the MIV0101A-1-B5 a central hub for precise motion control in high-performance machining centers.

By converting real-time CNC commands into clean,regulated current,the MIV0101A-1-B5 enables synchronized dual-axis operation with minimal latency.Its rack-mounted,hot-swappable design ensures rapid replacement and easy maintenance.Despite being phased out in favor of newer VAC5 solutions,its robust build and widespread field refurbishment make it a popular choice for sustaining legacy platforms.

For tasks like 5-axis contouring,rotary table indexing,or multi-axis mill-turn operations,relying on MIV0101A-1-B5 is a safe bet—it delivers steady torque,smooth transitions,and real-time responsiveness.It continues to empower precision machining in aerospace,mold-making,and mold repair sectors.

Core Advantages and Technical Highlights

Dual-axis coordination

The MIV0101A-1-B5 handles two axes of servo control in a single module,allowing synchronized movement without the complexity of linking separate drives.Ideal for rotary table and multi-axis transitions.

ICB2 controller enables tight feedback loops

Equipped with an ICB2 control board,the MIV0101A-1-B5 accurately tracks motor position with high-resolution encoder input.That precision ensures repeatable machining accuracy and stable contouring at high feed rates.

Efficient thermal design

Heat sink brass fins and a built-in active cooling fan ensure the MIV0101A-1-B5 remains within operational limits even under continuous production load—eliminating thermal throttling in harsh environments.

Hot-swap maintenance

Minimize downtime with plug-and-play replacement—technicians can swap failed modules without CNC shutdown.The MIV0101A-1-B5 slot-compatible design supports quick field service and part stocking.

Advanced protection logic

Integrated safeguards guard against over-current,voltage spikes,and thermal overload.The module’s rapid-response shutdown traces faults before they affect the rest of the machine.

Backward compatibility

Although designed for Okuma’s MIV lineup,the MIV0101A-1-B5 works with older VAC3/VAC III-style backplanes,enabling drop-in upgrades without rewiring or firmware changes.

Typical Application Scenarios

The MIV0101A-1-B5 is tailored for dual-axis operations in precision machining cells.In mold-making centers,it drives a B-axis rotary table while coordinating with vertical feed for undercut features—achieving sub-10µm repeatability and smooth contour transitions.

On aerospace part lines,it powers high-speed 2-axis drilling along composite curvature,where torque stability and synchronized motion matter most.Engineers choose the MIV0101A-1-B5 to suppress vibration and keep tool engagement consistent.

In automotive fixture calibration systems,the MIV0101A-1-B5 controls indexing plates and servo clamp mechanisms,delivering reliable performance during long run hours.Its dual-drive nature reduces cabinet complexity and simplifies maintenance.

Used in EDM rotary tables or multi-axis trimming cells,the MIV0101A-1-B5 sustains precise motion without introducing backlash—critical for accuracy and scrap reduction.Its proven durability and refinement make it a veteran’s pick in legacy CNC series.

Installation,Commissioning and Maintenance

Installation Preparation:Power down the CNC cabinet and verify the backplane for bent pins or foreign debris.Confirm that the 200–220 V AC supply is stable and protected via breaker.Insert the MIV0101A-1-B5 firmly in its slot,ensure the cooling fan is unobstructed,and reconnect axis motor and encoder cables to labeled ports.Follow with a soft power-up;a steady LED confirms proper initialization and toolpath-ready state.

Maintenance Suggestions:Conduct monthly visual inspections—check fan operation and LED indicators.Use compressed air to remove dust from fins and airflow vents.At any sign of torque fluctuation or thermal warning,power off,remove the drive,and bench-test the fan and heat sink.A failed module can be hot-swapped thanks to its dual-axis design and slot compatibility.Preserve connectors by avoiding excessive cycles.
