Product Description:

The MIV06-1-B1 is a servo drive module produced by Okuma and assigned to the MIV Servo Drives series. As an Okuma Inverter Unit, it converts the common DC bus energy into phase-modulated outputs for brushless (BL) and PREX motors while relaying encoder feedback to the master controller. Within industrial automation, the unit sits between the CNC processor and the machine's motion hardware, supplying regulated current and real-time status so that machining centers, lathes, or gantry systems maintain commanded trajectories under dynamic load. This arrangement lets the CNC command torque and speed changes without placing the power electronics inside the control processor.

Its control section receives 24 VDC logic power, keeping internal processors active even when the main bus is disabled. The power stage draws from a 300 VDC DC bus that is distributed by the converter rack, and it can return regenerative energy to that bus during deceleration. The module governs 1 axis, so one BL or PREX motor is energized per drive. Continuous output is limited by the L side capacity of 6.0 kW, which is the maximum spindle or feed-axis power. Command, status, and position data travel over Servo / Encoder / Converter links, a dedicated back-plane network that synchronizes this drive with adjacent axes. The regenerative path helps reduce wasted braking energy when the connected axis slows down. These signals are identified by a 5-bit controller ID switch that assigns the logical address within the rack.

Thermal management relies on 2 axial fans that pull air across the heat sinks and expel it through the cabinet roof. The chassis stands 380 mm tall, spans 100 mm across the front panel, and extends 325 mm from the mounting rail. This footprint allows multiple MIV modules to be stacked in one enclosure while leaving room for connector access and vertical airflow between neighboring drive channels.
