Variable Frequency Drive 11 kW – Mitsubishi FR-SE-2-11K-A
The FR-SE-2-11K-A is an 11 kW variable frequency drive (“Variable Frequency Drive / Inverter”) manufactured by Mitsubishi Electric, belonging to the FREQROL FR-SE series. The voltage class is 200 V three-phase, with a rated output power of 11 kW; the suffix “A” denotes the product revision. This drive is used for AC motor speed control on CNC machine tools, machining centres, and industrial automation systems; it may control the main spindle or auxiliary axes depending on the machine configuration.
The variable frequency drive converts fixed-frequency mains voltage into a three-phase output with variable frequency and amplitude, enabling precise speed and torque control of AC motors. In a CNC machine tool, failure of this component results in the immediate stoppage of the spindle or controlled axis, making it impossible to continue machining and potentially resulting in loss of the workpiece in progress; it is therefore a critical component for production continuity.
Mitsubishi Electric is a Japanese multinational corporation founded in 1921, a world leader in the production of industrial automation systems, inverters, servo drives, and CNC systems. The FREQROL FR-SE series is a general-purpose inverter line produced during the 1990s–2000s; all models in this family are legacy / discontinued and available exclusively as used, surplus, or through specialist repair services.
