Product Description:
The MIV14-3-V5 is an Okuma inverter unit assigned to the MIV Servo Drives series. As a servo drive, it conditions DC bus power and sends timed switching commands so a linked VAC motor can follow numerical-control position and velocity demands on machine-tool axes. The closed-loop architecture lets the CNC correct motor response as load changes during cutting and rapid traverse moves. Okuma supplies this model for compact, panel-mounted automation where a single axis requires closed-loop torque, speed, and position regulation.
The drive is configured for a single-axis workload, so its power stage, current sensors, and feedback channels are dedicated to one motor channel. Control electronics draw a stable 24 VDC from a separate supply, while the power section relies on a 300 VDC bus that is typically generated by a shared MIV rectifier. This arrangement separates low-voltage control power from the main energy path and supports stable logic operation during machine startup. A continuous output of 14 kW allows the unit to maintain commanded torque during extended machining passes without thermal derating. Internal regulation and regenerative functions are managed by the ICB3 inverter control board, which also stores the ladder parameters used with Control ROM Type 5 to match the VAC motor’s resolver feedback and current limits.
The enclosure weighs 11.2 kg, which helps when planning direct-panel or top-hat rail mounting inside sealed control boxes. Its face measures 150 mm in width and 380 mm in height, and the 325 mm depth keeps the footprint compact while leaving room for airflow across the heat-sink fins. These front dimensions also help the module fit beside companion drive hardware in dense cabinets. The speed monitor produces 1 volt for every 1562 min⁻¹/V of motor speed, which supports external analog speed monitoring, and the voltage error scale of 1/42 supports PI loop verification with a handheld meter. Termination points are secured by M6 and M8 screws at XT1 and XT2 to complete the power and brake wiring paths.
