OKUMA BLII-D200A Servo Drive 200A

Buy online your OKUMA BLII-D200A Servo Drive from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

This OKUMA BLII-D series servo drive is designed to control and power BL servo motors in Okuma CNC machine tools. It is widely used as a replacement unit or spare part to restore reliable axis performance on lathes and machining centers.

The BLII-D200A is a 200 A servo amplifier that delivers precise current, speed and torque control while ensuring stable closed-loop axis operation. It converts DC bus power into controlled three-phase output for compatible Okuma BL servo motors and incorporates protection functions against overcurrent and overheating.

This drive is intended for direct replacement on Okuma machines equipped with BLII-D servo systems. Matching the same series and current rating helps preserve the original wiring, connectors and machine parameters, reducing installation time and minimizing downtime.

Its panel-mounted design integrates easily into existing Okuma electrical cabinets, making it suitable for maintenance, retrofit and repair projects on legacy CNC equipment.

Maintenance teams frequently keep the BLII-D200A in stock to quickly replace faulty servo amplifiers, restore machine availability and reduce production interruptions. It is commonly used to resolve servo alarms, axis faults and unstable motion while extending the service life of existing Okuma CNC systems.

Each unit can be tested by skilled engineers on dedicated CNC simulators before shipment to verify electrical performance and proper operation. It is supplied with protective industrial packaging, warranty coverage and worldwide shipping. Repair service, exchange service and obsolete part sourcing are available through Cnc-shopping to help maintain older Okuma installations.

Frequently asked questions about BLII-D200A:

How do I confirm compatibility with my Okuma cabinet
Match the full code on your existing amplifier to BLII-D200A, verify the current class and the BLII-D series label, and compare the connector layout and mounting holes. Also check the motor nameplate and control cabinet documentation to ensure the drive rating aligns with the axis it powers.

Is the 200 A model intended for any specific axis type
It is selected for axes that require higher current capacity. Use the same rating as the original unit to keep performance and protection behavior consistent with the machine design.

Will parameters need to be reloaded after a like-for-like swap
When replacing with the exact same reference, the CNC usually retains the required settings and the wiring remains unchanged. Follow your machine documentation and backup procedures to confirm parameter integrity before power up.

Do you provide repair or exchange service for this drive
Yes, depending on condition and availability, repair or an exchange service can be arranged to shorten downtime. Contact us with the fault description and the unit tag for a repair turnaround estimate.

Can this be used as a temporary drop-in during troubleshooting
Many maintenance teams keep a BLII-D200A as a replacement unit to isolate faults and restore motion quickly. Swapping in a known-good drive helps confirm whether the issue is in the amplifier or elsewhere in the axis chain.
