Technical Principles and Innovative Values

Innovation Point 1:Precise Motion Control

The OKUMA BDU-30D uses IGBT PWM control to deliver 25A continuous current,ensuring accurate torque and speed for motors like the BL-50E-20.It reduces axis jitter by 30%compared to standard DC drives,ideal for low-speed,high-accuracy CNC tasks like drilling.

Innovation Point 2:Integrated Diagnostics

Featuring red and yellow LED indicators(e.g.,PSON green for power,red for alarms like OCM or OV),the BDU-30D provides real-time fault detection,cutting troubleshooting time by 40%.Alarms like overcurrent-motor(OCM)or overvoltage(OV)are instantly actionable via OSP protocols.

Innovation Point 3:Compact and Robust Design

With a 350x150x120mm frame and large-current PC board,the BDU-30D thrives in harsh environments up to 55°C with IP54 cabinet protection.It offers 20%longer lifespan than non-protected drives in dusty CNC workshops.

Innovation Point 4:Seamless Motor Integration

Optimized for the BL-50E-20 motor(1kW,2000 RPM,5.3 N-m),the BDU-30D amplifies command signals for precise motion,supporting Okuma’s 5000 control systems.Its single-axis design simplifies setup,reducing installation time by 25%compared to multi-axis drives.

Application Cases and Industry Value

In a German automotive plant,the OKUMA BDU-30D powered a CNC lathe with a BL-50E-20 motor for gear machining.Its 25A current control reduced dimensional errors by 90%,boosting output by 12,000 units annually.LED diagnostics resolved a bad gate board issue in minutes,saving€30,000 in downtime costs.

In a U.S.metalworking facility,the BDU-30D drove a CNC milling machine for precision parts.Its stable 2000 RPM performance and OSP integration cut surface finish errors by 85%,increasing throughput by 10%.The drive’s compact design fit tight control cabinets,proving its versatility in high-precision applications.
