OKUMA MIV08-1-P1 1-Axis Servo Drive

Buy online your OKUMA MIV08-1-P1 1-Axis Servo Drive from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The OKUMA MIV08-1-P1 is a single-axis servo amplifier designed for OKUMA CNC machines equipped with OSP controls. Its primary function is to drive and control one AC servo motor axis, providing precise torque, speed, and position regulation for reliable machine movement and accurate positioning.

Part of the OKUMA MIV series, this servo drive operates within a closed-loop control system where the CNC manages position commands while the amplifier controls motor current and velocity. This architecture ensures smooth axis response, stable motion, and repeatable positioning performance on linear and rotary axes.

The MIV08-1-P1 is designed for use with a 7.5 kW (10 hp) servo motor and is commonly installed on CNC lathes, machining centers, and other OKUMA machine tools. It integrates directly into existing machine cabinets using the original wiring, connectors, and control interfaces, making it a practical replacement solution when a servo amplifier failure occurs.

Typical symptoms of a faulty amplifier include servo alarms, unstable axis movement, overcurrent faults, servo enable errors, or unexpected machine stoppages. Replacing the unit with a matching MIV08-1-P1 helps restore normal machine operation while maintaining the original servo tuning and control parameters.

Manufactured in Japan, the OKUMA MIV08-1-P1 is built for continuous industrial operation in demanding production environments. Although this model has been discontinued, it remains widely used as a replacement part, refurbished unit, or emergency spare for legacy OKUMA machines. Keeping a compatible amplifier in stock can significantly reduce downtime and support the long-term maintenance of OSP-based CNC systems.

Frequently asked questions about MIV08-1-P1:

How do I confirm that MIV08-1-P1 is the right drop-in for my machine?
Match the full code on your existing amplifier and confirm the OSP control generation on the machine. Share the machine model and axis designation so we can verify pairing with the installed servo motor and cabinet layout.

Which axes can this module drive?
It is a single-channel servo amplifier used for linear axes such as X, Y or Z, and can also be used for rotary positioning axes when specified by the machine builder. Motor pairing and parameters must correspond to the original OKUMA configuration.

Will I need to reload parameters after replacement?
Axis parameters are typically stored in the CNC, not the power amplifier. After installing the replacement unit, follow the machine’s standard procedure to verify axis address, servo enable and any model-specific settings before resuming production.

Can you help with refurbished or exchange options?
Yes, depending on condition and availability we can offer a refurbished unit, an exchange service to reduce turnaround, or a repair service for your faulty drive. Contact us with your unit’s code and fault details for the best route.
