Product Description:

The MIV22-3-V3 inverter unit is produced by Okuma as part of the MIV Servo Drives series. Designed for CNC and general factory automation, this module links the machine controller to a servomotor and delivers pulse-width-modulated power with regenerative braking on one axis. Its role is to maintain commanded velocity and position loops while sharing a common DC bus with other inverters, improving energy efficiency across the installation. This arrangement makes the unit suitable for machine layouts that require coordinated servo control without adding a separate power stage for each function.

For motion execution, the drive handles 1 controlled axis, so parameter files, fault logs, and diagnostic routines are dedicated to a single motor channel. Incoming control logic is supplied at 24 VDC, separate from the high-energy section that draws from a 300 VDC common bus; this split supply helps preserve control functions when the main line is removed. The left-hand power segment is rated for 22 kW, allowing the inverter to supply the current needed during rapid acceleration and deceleration. Operating status is reported on a 7-Segment LED display, and the front panel supports two display modes that switch between alarm codes and live bus information. This display arrangement makes operating status easier to check during normal use.

Cabinet layout is supported by the unit’s footprint. The chassis depth is 325 mm, the height is 380 mm, and the width is 150 mm, so multiple inverters can be arranged neatly in a standard enclosure while leaving room for airflow. Heat-dissipating fins and a sturdy frame support thermal stability, and the listed mass is 11.2 kg. All power terminations are placed on the left side, which helps keep cable routing orderly in tightly packed panels. The two display modes remain visible when drives are mounted side by side, which helps preserve front-panel readability in dense cabinet installations.
