Product Description:
The MIV-02-1-B5 is an inverter unit manufactured by Okuma as part of the MIV Servo Drives series. It converts DC-link energy generated by the main converter into regulated three-phase power for precision servo control, allowing CNC machinery to position axes using encoder feedback. By integrating servo, encoder, and converter communication links, the unit serves as a compact drive element in industrial automation systems that require accurate motor response and close coordination with the master controller.
Control circuitry operates from a 24 VDC supply, keeping the logic circuits isolated from the power stage. The drive supports one mechanical channel through its single-axis control architecture, simplifying parameter management for one motor. A shared bus rated at 300 VDC feeds the IGBT bridge, a voltage commonly used in mid-power machine tool installations. Continuous output is limited to 2.8 kW, establishing the thermal limit for sustained operation with BL or PREX motors. The slim face width of 60 mm allows multiple inverters to be mounted side by side on a DIN rail while maintaining airflow. The module operates as a network slave station, so sequencing and diagnostic commands originate from the upstream CNC or motion controller through the designated communication links.
The unit has an overall height of 380 mm and a chassis depth of 325 mm, allowing space behind door-mounted wiring ducts. Its installed mass is 5.7 kg, which permits manageable handling while providing stability after the unit is secured inside the cabinet. After mains power is removed, the internal capacitors discharge to a safe voltage within 2 minutes, permitting prompt access to connected motors or encoders. Address allocation in multi-axis systems is handled by a 5-bit controller ID switch on the left side, simplifying system setup without requiring additional hardware.
