Product Description:

The MIV0202A-1-B5 is an Okuma inverter unit that belongs to the MIV Servo Drives series. As a second-generation module, it forms part of the multi-axis drive stack on Okuma machining centers, converting the shared DC bus into phase-controlled outputs for paired servomotors. By integrating two amplifier channels on a single frame, the unit streamlines cabinet layouts and supports rapid, coordinated motion in industrial automation cells. This arrangement also reduces the number of separate drive housings needed for machines that use closely synchronized axis movement.

An internal control circuit operates from 24 VDC, energizing the logic boards, gate drivers, and status indicators independent of the main power section. DC link energy enters the unit at 300 VDC, allowing it to modulate voltage and frequency for each side without a separate rectifier. The module supervises 2 axes, identified as L and M, so one housing can drive paired machine functions such as feed tables or an auxiliary motion axis. Continuous output per channel reaches 2.0 kW, supplying enough power for medium-sized BL or PREX servomotors under sustained duty. Despite this electrical capacity, the panel footprint is limited to a width of 60 mm, permitting high-density mounting alongside additional axis cards and I/O. Independent low-voltage control power also helps the unit maintain monitoring and communication functions during main power transitions.

The enclosure stands 380 mm tall and extends 295 mm in depth, dimensions that affect rail spacing and door clearance inside the control cabinet. An installed mass of 5.5 kg keeps the unit manageable during installation while still providing enough thermal mass for stable temperature rise. The drive interfaces directly with Okuma’s BL Motor / PREX Motor families through keyed power plugs and digital encoder ports. This direct motor connection supports closed-loop response on machine axes where stable position and velocity control are required through repeated duty cycles.
