Drive CPU Board – MITSUBISHI SE-I01
The SE-I01 is an electronic drive CPU control board (“Drive CPU Board”) manufactured by Mitsubishi Electric, belonging to the drive family for MELDAS / MELSERVO CNC systems. The board integrates the main microprocessor responsible for executing drive control algorithms (current and speed loops), managing serial communications with the CNC unit, and supervising the converter’s hardware protections. It can be installed in servo and/or spindle drives of the compatible series.
The drive CPU board is the computational core of the drive unit: it receives position or speed references from the CNC controller, executes real-time regulation algorithms and generates commands for the power stage. A failure of this component renders the drive completely inoperative, preventing any controlled axis or spindle movement and causing an immediate machine stop.
Mitsubishi Electric is one of the world’s leading manufacturers of CNC systems, servo drives and industrial automation; its FA (Factory Automation) division has developed MELDAS numerical controllers and MELSERVO drives since 1970, widely used in milling machines, lathes and machining centres. Boards of this generation are legacy / discontinued: available only as used parts, surplus stock or through specialist repair centres.
