Product Description:
The MIV06-3-V3 inverter unit is produced by Okuma and belongs to the MIV Servo Drives series. Designed as an intermediate section between the DC link and a matched VAC motor, it modulates power so that the machining center’s numerical controller can adjust speed and torque without mechanical belts or gear changes. By performing closed-loop current and velocity regulation, the drive supports precise tool positioning and helps shorten cycle times in automated production cells. Within Okuma’s electrical cabinet architecture, it occupies a compact slot and shares a common power rail with other spindle or feed axes.
The unit has a single-axis configuration, so one motor channel is energized and monitored through the servo, encoder, and converter communication links that form the internal feedback chain. The control electronics operate on 24 VDC, providing low-voltage power for the gate-firing logic and related circuits. A separate converter supplies the 300 VDC bus used by the inverter as its main energy source. The inverter converts this DC input into a three-phase output with a continuous capacity of 6.0 kW. This output is suitable for mid-frame feed drives used on X- or Y-axis tables and provides additional capacity for acceleration peaks.
The unit has a frame width of 100 mm, a height of 380 mm, and a depth of 325 mm. These dimensions allow the heat-sink fin stack to align with standard 200 mm pitch rails inside the electrical cabinet. The unit weighs 7.3 kg, allowing it to be mounted without specialized lifting equipment. Two display modes are available, and operating status appears on a 7-segment LED that presents alarms and ready codes numerically. Field wiring terminates on the XT1 and XT2 terminal blocks, which accept M6 and M5 screws, respectively. The aluminum chassis provides a continuous grounding path around the terminal lugs.
