The Bosch Rexroth R911248878 (TDA 1.1-100-3-API) is a main spindle controller designed for integration in industrial environments. The device requires precise installation of its programming module prior to operation and features sub-miniature D-type connectors that must be securely fastened during use. For DC bus connections using flexible cables, wires of similar length and short, stranded design are mandatory. The unit offers an analog command input, supports continuous effective current of 70 A and rated current of 100 A, and operates with a power consumption of 1.4 A at 24 V load voltage and 160 mA at ±15 V test voltage. Operating humidity should not exceed 70% relative with no condensation, and storage or transport must be within -30°C to 85°C. The controller includes an onboard diagnostic display and has a mass of 10.5 kg. Power must be disconnected before changing the programming module to prevent component damage.
