Product Description:
The MIV02-1-B5 inverter unit is manufactured by Okuma for the MIV Servo Drives series. It converts energy from the shared DC link into motor-specific voltages while collecting encoder information, allowing the CNC to regulate torque and speed for the connected mechanical axis. The module serves as the power and feedback interface between the system bus and BL/PREX servo motors in automated machining centers. This arrangement allows the controller to coordinate motor current with position feedback during acceleration, steady motion, and deceleration.
The drive governs one axis, so its parameters and fault logs relate to one motion channel. Low-level electronics receive a stabilized supply of 24 VDC, which isolates the control logic from the main power section. The inverter draws energy from a shared 300 VDC bus, which can also return regenerated power to the supply converter. Nominal output on the L side is 2.0 kW, making the unit suitable for compatible medium-frame BL/PREX motors. Commands and feedback travel through the Servo / Encoder / Converter link, providing time-aligned position and current data to the CNC. A 5-bit address switch assigns the module a unique controller ID when multiple drive units share the enclosure.
The housing is only 60 mm wide, supporting dense side-by-side placement within the drive cabinet. It extends 325 mm in depth, so the cabinet must provide sufficient clearance for the body and its connections. Its height is 380 mm, and vertical airflow paths must remain unobstructed when drive units are arranged in a rack. The narrow front profile preserves space for adjacent modules while allowing the power stage and heat sink to fit within the deeper enclosure. The total assembly mass is 5.7 kg, allowing the module to be secured on cabinet rails rated for the installed load. Proper spacing around the housing helps heated air leave the power section without obstructing nearby busbars or control wiring.
