Okuma MIV servo drives are key components in Okuma CNC machines, responsible for precise axis control and stable machine operation. Over time, these units may develop faults due to aging components, thermal stress, or electrical issues.
In this article, we briefly explain the difference between repair, exchange, and compatibility of Okuma MIV servo drives.
Repair vs. Exchange – What’s the Difference?
Repair means restoring your original MIV unit by replacing defective electronic components, followed by full functional testing.
Exchange means receiving a fully refurbished and tested replacement unit, while your defective drive is returned to us as a core.
Both options are commonly used in industrial environments, depending on urgency and availability.
1 Axis and 2 Axis MIV Units
Okuma MIV drives are available in different configurations:
- 1 Axis units – control a single machine axis
- 2 Axis units – control two axes in one module
Choosing the correct version is critical for compatibility with your CNC system.
Common Symptoms of Faulty MIV Drives
- Axis alarms or intermittent errors
- Overheating
- No axis movement
- CNC startup failures related to servo systems
If these issues occur, professional diagnosis is strongly recommended.
Professional Testing Matters
All refurbished MIV servo drives offered by Schirmer GmbH are:
- tested under load
- electrically measured
- verified for full functionality before shipment
This ensures reliability and minimizes machine downtime.
