Product Description:

The MIV22-1-B1 inverter unit is produced by Okuma within the MIV Servo Drives series. It functions as a power and control interface in industrial automation, converting the shared DC link energy into three-phase outputs for matched BL or PREX servo motors. Positioned between the CNC controller and the electromechanical load, the drive closes the velocity and position loops for one motion channel, ensuring coordinated movement and torque delivery during machining or material-handling tasks.

This drive is designed for a single axis; the specification lists an axis count of 1, meaning all resources on the module support one motor at a time. Low-level logic, gating, and diagnostics are powered from a dedicated control supply of 24 VDC, while the power stage draws from a shared DC bus rated at 300 VDC. The L-side output capacity reaches 22 kW, allowing the unit to handle motors up to 30 hp without derating. Command and feedback travel through the control links denoted as Servo / Encoder / Converter; this trio carries drive commands, incremental or absolute position data, and DC bus status so the host controller can implement synchronized motion and active fault supervision.

For cabinet layout, the housing stands 380 mm high, spans 150 mm wide, and extends 325 mm deep, giving service personnel clear clearance figures when planning vertical stacks or side-by-side installations. A mass of 11.2 kg keeps the drive light enough for rail mounting yet heavy enough to serve as a thermal sink. The front panel accepts an MFP1 display card for parameter entry and alarm viewing. Power wiring terminates on the 1-179276-2 AMP AC connector, while feedback from the external encoder plugs into the D02-M15SAG-13L9 JAE EPG connector. These standardized interfaces simplify replacement and keep field wiring consistent with other Okuma motion modules.
