Product Description:

The MIV06DB-1-B8 inverter unit is manufactured by Okuma as part of the MIV Servo Drives series. Designed for motion control in CNC machining centers, this product conditions DC bus energy and executes pulse-width modulation so that BL and PREX servo motors receive the current profile they require for precise positioning and speed regulation in industrial automation cells. As an inverter unit, it forms the power segment of a distributed axis loop by converting the plant DC supply into controlled three-phase output for commanded motion.

At the control level, the drive supervises a 1-axis motion channel and draws housekeeping power from a 24 VDC supply, while a separate link furnishes 300 VDC to its IGBT bridge. The L-side power stage is rated for up to 8 hp or 6.0 kW, allowing it to energize medium-frame spindles and linear axes. The internal ICB1 inverter control board performs PWM generation, current feedback, and fault detection. A peak torque reference of 3 V is accepted on the analog input, allowing simple voltage scaling from the host motion controller. Command and feedback lines terminate on a 53460-0611 Molex signal connector for straightforward signal wiring.

For multi-axis applications, several drives can be daisy-chained, and a loop may include up to 8 modules, span 100 m, and permit individual unit spacing of 25 m from the next node. Speed feedback is interpreted on a scale of 1562 rpm/V, giving the controller predictable resolution across the operating range. Cabinet layout is simplified by the enclosure dimensions of 100 mm in width, 380 mm in height, and 325 mm in depth, so adjacent equipment can be packed tightly without disturbing airflow. The housing is sized to match standard rail hardware, which helps keep cabinet installation straightforward in multi-drive systems.
