Product Description:
The MIV01A-1-B5 inverter unit is produced by Okuma for the MIV Servo Drives series. It belongs to the manufacturer’s motion-control platform and interfaces with BL and PREX servo motors used in CNC machining centers and automated material-handling cells. By accepting command data from an Okuma control board, the drive modulates its internal power stage so that a mechanical axis follows programmed velocity and position profiles. Feedback-based monitoring also protects the system against overcurrent conditions and DC-bus irregularities during operation.
The drive supports an axis count of 1, so its monitoring, gating, and regenerative functions are dedicated to a single motor channel. Logic circuits are energized by a control supply of 24 VDC, which keeps the microprocessors and interface relays active when the main power link is disabled. The power section receives a DC bus voltage of 300 VDC. IGBT devices switch this high-energy rail to produce three-phase output power for the motor windings. Continuous shaft power on the L side reaches 1.0 kW, or 1.33 hp, providing power for light to medium cutting, feed, or auxiliary axes. The package has a mass of 5.7 kg, which should be considered when selecting cabinet supports and mounting hardware. An ICB1 control board and ROM type 5 are installed to support the required Okuma control configuration.
The housing measures 380 mm in height, 325 mm in depth, and 60 mm in width, allowing the unit to be stacked vertically beside other MIV modules. Main power terminates at the XT1 terminal, which accepts an M6 screw, while auxiliary connections use an M4 screw at the XT2 terminal for signal grounding. Motor leads connect through a 1-178137-2 AMP connector, and encoder feedback enters through a D02-M15SAG-13L9 JAE plug. Status lines terminate at a 53460-0611 Molex header. These keyed connectors help prevent mismatched connections and reduce wiring errors during maintenance.
