Product Description:

The MIV0404-1-B1 is an Okuma inverter unit in the MIV Servo Drives series. It combines a control board, display card, and power inverter in one chassis to regulate two servo channels without separate amplifier sections. This integrated layout lets the CNC controller manage paired axes from one housing instead of using multiple independent modules. In industrial automation, the drive conditions a DC bus and supplies modulated three-phase power so connected BL and PREX motors receive the commanded speed and torque needed for coordinated motion on lathes and machining centers.

The unit delivers a continuous output of 4.0 kW × 4.0 kW, so both channels can operate at the stated rating. A built-in dual inverter topology supports 2 axes identified as L and M, which reduces cabinet space compared with separate single-axis modules. Motor current is processed by the ICB1 control board, which manages gate timing, overcurrent detection, and status feedback during operation. Internal logic and I/O run from a 24 VDC control supply, while the switching stage is fed from a shared 300 VDC bus. This separation keeps low-voltage control circuits distinct from the main power section. Standard ROM 1 stores servo parameters and alarm history, and terminal markings keep the wiring layout easy to follow.

The enclosure measures 100 mm in width, 380 mm in height, and 325 mm in depth. Its mass is 7.8 kg, which keeps the assembly relatively manageable when mounted in a vertical rack. These proportions support dense panel layouts and allow multiple units to be installed side by side with little unused space. The supplied configuration includes the control board, display card, and inverter as one assembled unit. Front-panel axis markings correspond to the two channels, so connections can be matched quickly during installation.
