Product Description:
The TDA 1.3-050-3-L00 spindle controller is produced by Bosch Rexroth Indramat and belongs to the TDA Main Spindle Controllers series. It serves as the power and control stage between a machine-tool CNC and the main spindle motor, translating high-level speed commands into regulated three-phase output so that turning, milling, or grinding operations can maintain stable cutting conditions. This arrangement allows the spindle to respond smoothly during acceleration, steady cutting, and deceleration, which helps keep machining processes consistent across changing loads.
This unit handles a rated output of 50 A and sustains a continuous effective current of 35 A, allowing it to drive high-inertia spindles without thermal overload. Its DC link is stabilized at DC 300 V, drawn from a common supply so multiple axes can share the same bus. A 24 V auxiliary bus requires only 1.2 A for logic functions, which helps limit the demand on the control cabinet supply. Speed references arrive over the SERCOS fiber ring, and the optical X4 light-wave port helps maintain signal integrity in electrically noisy environments. Positioning instructions from the CNC enter through the X2 37-pin interface, and no additional encoder or fieldbus options are installed. Enclosure protection is rated at IP 10, so the unit must be installed inside a filtered cabinet where convection airflow can remove heat from the power electronics.
The controller fits standard panel layouts with a width of 150 mm, a depth of 355 mm, and a height of 390 mm. At a mass of 10.5 kg, the unit remains manageable for cabinet installation without special handling equipment. Reliable operation is permitted at ambient temperatures up to +55 °C and at site elevations up to 1000 m. It is intended for enclosed machining centers where dust, chips, and coolant remain inside the machine envelope. The low-leakage housing and optical command connection support stable operation in cabinets used for industrial spindle control.
