Product Description:

The MIV03-1-P1 is an inverter unit manufactured by Okuma for the MIV Servo Drives series. As an integral component between the converter and the servo motors, it manages power delivery and motion commands for machining and material-handling equipment. The unit is intended to operate PREX motors and uses dedicated servo, encoder, and converter links for coordinated control. This arrangement allows precise position and velocity regulation in automated production cells. It also serves as the interface that ties motor feedback to the converter section during axis operation.

This model supports 1-axis operation, so one drive controls one machine slide or spindle. Internal logic and I/O are powered by a 24 VDC control rail, which keeps low-level electronics separate from the main power circuit. This separation helps protect control circuits from the higher-energy bus section during normal operation. The main DC bus operates at 300 VDC, providing the energy reserve needed for rapid torque transients without sag. Okuma lists an L-side capacity of 4 hp, which is the continuous mechanical output the matched motor can deliver while the inverter remains within its thermal and electrical limits. Command processing is handled by an ICB1 control board, and synchronized data over the servo, encoder, and converter links keeps the position loop closed during operation.

The cabinet footprint is compact, with a width of 60 mm, a depth of 325 mm, and a height of 380 mm. These dimensions support side-by-side mounting with other MIV modules while still leaving room for cable routing and airflow in a control rack. A transport mass of 5.7 kg allows the unit to be handled without lifting equipment during installation or service. Its tall, narrow housing also fits well in dense machine enclosures where rack space is limited. The layout leaves practical clearance for adjacent modules and front-access wiring.
