Product Description:
The MIV102A-1-B5 is an inverter unit produced by Okuma for the MIV Servo Drives series. It converts the shared DC link energy of a multi-axis system into regulated three-phase output that governs torque and speed loops in CNC machining centers and other automated equipment. Positioned between the motion controller and the servo motor, the module provides the power stage that enables coordinated interpolation and precise positioning required for industrial automation tasks. This arrangement allows the control system to send motion commands while the inverter supplies the regulated output needed for stable axis response.
The unit operates from a DC bus of 300 VDC, establishing the maximum voltage supplied to the motor windings. Control logic is maintained by a separate 24 VDC supply, so parameters and diagnostics remain available when the main bus is powered down. A continuous-to-peak capacity window of 1.8 × 2.8 kW matches the thermal margin of the output transistors. Compatibility with BL motor and PREX motor types allows use on high-response axes or energy-efficient spindles without changing the basic drive setup. The inverter control board specified as ICB1 works with type 5 control, aligning switching patterns and feedback handling with current Okuma motion algorithms for stable speed and torque regulation.
The housing weighs 5.5 kg, which supports direct panel mounting without additional support brackets. Overall height is 380 mm and depth is 295 mm; with a front width of 60 mm, several units can be stacked in a narrow cabinet while still leaving airflow channels. Classified as a Second Generation inverter, the module includes updated heat-sink fins and gate drivers for improved thermal handling in compact enclosures. Connection hardware uses an XT1 power terminal secured by an M6 screw and an XT2 control terminal tightened with an M4 screw for secure electrical attachment.
