Product Description:
The TDA-1.3-100-L00 is a spindle drive controller produced by Bosch Rexroth Indramat for the TDA Main Spindle Controllers series. The unit functions as the power and communication link between a CNC or PLC and a high-speed main spindle motor, converting digital speed and position commands into regulated three-phase currents. This allows the controller to support the precise torque and speed control required for machining, drilling, and grinding tasks in automated cells. It is intended for spindle applications where stable speed regulation and coordinated motion with the machine control are required during continuous operation.
With a rated current of 100 A, the controller can deliver high spindle torque during acceleration, while a continuous current of 70 A indicates its long-term current capacity. An internal capacitor bank maintains a DC link voltage of 300 VDC that feeds the inverter stage. Logic electronics are supplied by a control bus voltage of 24 VDC, which separates low-power circuits from the mains section. Motion data and diagnostics travel over the SERCOS fiber-optic command interface, providing deterministic cycle times for multi-axis systems. Heat generated by the power semiconductors is expelled through the air-inside-cabinet cooling method, so enclosure airflow must be managed to keep components within tolerance.
Auxiliary electronics draw 1.4 A from the control bus, and test points are energized by ±15 VDC for oscilloscope measurements. The cabinet blower that serves this drive operates from 220 VAC, and installation must respect a +55 °C maximum ambient temperature to avoid derating. A vertical mounting orientation inside cabinets up to 1000 m elevation maintains clear convection paths, while the housing’s IP 10 ingress rating limits use to clean indoor locations. No additional encoder or fieldbus ports are provided, so integration relies solely on the primary fiber loop. The controller has a mass of 10.5 kg, which supports stable cabinet mounting and practical handling during installation.
