Product Introduction

The Okuma MIV0103-1-B5 L-M is a dual-axis servo drive/inverter module purpose-built for Okuma’s MIV series CNC machines.Engineered to control both spindle and axis motors,this module delivers 1.0 kW to the L-axis and 3.0 kW to the M-axis.A crucial detail:it integrates the ICB1 controller board with Type 5 ROM,ensuring compatibility with Okuma’s CNC platform.The casing features built-in heat sink cooling and rugged housing for harsh factory environments.

Designed for precision machining centers,the MIV0103-1-B5 plays a central role by converting command signals from the CNC controller into regulated power output for dual-axis servo motors.Its compact,hot-swappable rack design supports quick serviceability and streamlined system upgrades.Despite being discontinued,it remains in demand for field maintenance,thanks to high reliability and straightforward replacement.

The MIV0103-1-B5 ensures smooth torque handling,fast response to command changes,and stable operation under strain—all essential in high-performance manufacturing.Whether installed originally or used in retrofit solutions,this drive module continues to support precision applications across aerospace,mold-making,and automotive component machining.

Core Advantages and Technical Highlights

Robust dual-axis strength

The MIV0103-1-B5 L-M provides simultaneous control over two axes—spindle and secondary axis—optimizing space and cost in CNC cabinet design by combining functions in one unit.

Precision control with ICB1

With its integrated ICB1 control board and Type 5 ROM,the MIV0103-1-B5 delivers precise motor management.That translates to clean pulse output,fast dynamic response,and reduced positioning error.

Heat-rated for harsh environments

Okuma’s built-in heat sink and fan support sustained operation at temperatures around 50°C.Its plastic enclosure resists dust and moisture ingress,perfect for high-usage machining cells.

User-friendly hot-swap design

Maintenance crews can swap the MIV0103-1-B5 in under five minutes,restoring production rapidly.No need to power down adjacent modules—perfect for critical uptime scenarios.

Field-proven durability

Though discontinued,this model is widely stocked rebuilt by service houses.OEM-spec components and exhaustive load testing under real conditions make it a durable field choice.

Seamless backward compatibility

Direct compatibility with earlier VAC series(D6,D11,D22)means no rewiring or firmware change—just slot in MIV0103-1-B5,and your machine is ready to go.

Typical Application Scenarios

The MIV0103-1-B5 excels in precision mold and die grinding,where spindle stability and dynamic axis control are critical.For example,in aerospace impeller machining,the unit has supported continuous 5-axis contour cutting,maintaining sub-micron repeatability without thermal drift.

On automotive gear-shaft lines,this drive has enabled fast 20 min cycle times by balancing L-axis feed motion and high-speed spindle operation,delivering consistent surface finishes under varying loads.

Legacy Okuma retrofit shops rely on the MIV0103-1-B5 to revive aging MIV series machines.Instead of discarding a$300k CNC,they swap in this refurbished module—machine runs as new,investment protected.

Also found in advanced EDM or high-speed drilling cells where torque regulation is pivotal,the MIV0103-1-B5 ensures feed motions sync with rapid spindle rpm changes—pulling absolute timing accuracy.

Installation,Commissioning and Maintenance

Installation preparation:Ensure the CNC rack is powered down and cleared of dust.Inspect the backplane for bent pins or debris;confirm proper input voltage(200–220 VAC)and rated circuit breaker protection.Remove the old drive and insert the MIV0103-1-B5,securing it firmly.Connect spindle/axis motor leads and ensure the fan has free airflow.Power up,and observe the front LEDs;green or blinking light indicates successful initialization.

Maintenance suggestions:Schedule visual inspections monthly—look for flickering LED,dust accumulation,or fan wear.Clean ventilation holes with compressed air.If torque performance or thermal warning arises,gently blow the heat sink fins and manually spin the fan shaft to check for binding.For severe faults,hot-swap the module using backed-up configuration;this action restores operation with minimal CNC interruption.Avoid excessive unplugging to preserve connector integrity.
