The Bosch Rexroth MPN R911244051 (TDA 1.1-100-3-A0I) is a main spindle controller for numerically controlled machine centers. It requires installation with 80 mm clearance above the cabinet and utilizes an internal ventilation system for cooling, with heat dissipation dependent on operating load. The controller supports three types of electrical connections and must be earthed using a conductor with a minimum cross-section of 10 mm². It is compatible with Bosch 2AD and 1MB motor series, provides analog command input (+/-10 V), and features an incremental encoder output. The DC link circuit requires a rated voltage of 300 V. The controller supports dynamic applications including C-axis interpolated operation. Electrical characteristics include a continuous effective current of 70 A, a rated current of 100 A, and a weight of 10.5 kg.
