R911244051
The R911244051 (TDA 1.1-100-3-A0I), crafted by Bosch Rexroth Indramat, is a specialized main spindle controller. Ensuring a minimum clearance of 80mm between the unit and the top of the installation cabinet is critical. The product has been designed to disperse heat through its vents, which is contingent on the device's load. It features three types of electrical connections, each serving differing functions of the device. The controller, equipped with a version code '2', necessitates an earthing cable with a conductor cross-section of at least 10mm2 for connection to the supply module.
Operating via internally generated airflow, the spindle controller is actively cooled during use. This controller, compatible with Bosch Rexroth's 2AD and 1MB motor series, boasts a modular design and is primarily utilized in numerically controlled machine centers. Its noteworthy features include high stiffness, a broad speed range under constant power, and precision control at low speeds. Augmenting its functionality, the controller can work alongside a power supply module for CNC machine tool tasks. Its spindle can operate as an interpolating axis in C-axis mode, and it comes with an incremental encoder output (excluding additional encoder input) facilitating thread cutting or position control. Additionally, the controller offers a terminal block for the integrated motor and DC link circuit, and it works with a +/-10V analog speed command value for NC controller connection.
