Product Description:
The MIV04-1-B5 is an inverter unit manufactured by Okuma and supplied as part of the MIV Servo Drives series. As an inverter, it converts a regulated DC link into controlled three-phase power for Okuma servo motors, allowing axis speed and torque to be modulated under CNC command. The module installs with the control board and display card to form a closed-loop drive that interfaces with encoder feedback and converter supplies, providing coordinated motion for machining centers and other industrial automation equipment.
This variant supports a single mechanical axis, identified by an axis count of 1, so the control board dedicates all processing resources to one servo channel. Low-level logic and relay circuits draw 24 VDC control power, which allows operation from the machine’s standard auxiliary supply even when the main DC link is off. The DC bus accepts 300 VDC, establishing the intermediate voltage that the inverter section chops into pulse-width-modulated output for the motor phases. Continuous mechanical output is limited to 4.0 kW, providing enough capacity for mid-range feed or spindle duties, and the electrical equivalent is listed as 5.3 hp for compatibility with horsepower-based sizing conventions. Cabinet footprint is minimized to a width of 60 mm, enabling the drive to fit alongside additional axes without expanding the enclosure.
Physical service access is aided by a depth of 325 mm and a height of 380 mm, allowing cable routing and airflow clearances typical of Okuma control cabinets. A mass of 5.7 kg keeps the unit manageable during installation while still providing the thermal mass required for stable temperature rise at rated load. The housing size supports secure mounting inside a multi-axis cabinet without crowding adjacent drive modules.
