Servo Drive Module – OKUMA MIV0101-1-B1
The MIV0101-1-B1 is a servo drive module (“Servo Drive Unit”) manufactured by OKUMA, a component of the axis control system for OKUMA CNC machine tools equipped with the OSP (Open System Platform) controller. The module manages speed, torque, and position regulation of a brushless servo motor, receiving commands from the CNC via a proprietary bus and returning position/speed feedback via a dedicated encoder. The part number MIV0101-1-B1 identifies hardware revision B1 of the MIV0101 family; other hardware revision variants may exist.
The servo drive module is the power and control element that converts CNC digital references into phase currents for the axis motor: it closes the position, speed, and current loops, ensuring the positioning accuracy typical of OKUMA machine tools. A module failure triggers the corresponding axis alarm, disables axis movement, and immediately stops the machine, preventing production from resuming until the unit is replaced or repaired.
OKUMA Corporation is a Japanese manufacturer founded in 1898 in Nagoya, specialising in CNC machine tools (lathes, machining centres, grinding machines) and the in-house OSP (Open System Platform) control systems developed entirely internally. It is one of the few manufacturers in the world that designs the machine tool, the CNC controller, and the drives entirely in-house. Products of the MIV series are legacy / discontinued: available exclusively as used, surplus, or through specialist repair services.
