The Bosch Rexroth Indramat KDA 3.3-050-3-DQI-U1 from the KDA Spindle Drives series is a high-stiffness main spindle drive optimized for demanding CNC and industrial applications. This Design 3 drive delivers a continuous performance profile characterized by precise positioning features and an extensive speed range, supported by a Rated Current of 50 A and a DC Bus Voltage of 300 V. Speed control is managed with a Digital 16-Bit Parallel Speed Command Value, while thermal management is provided by a forced cooling system using a Heatsink Blower powered by 115 VAC. Integration is simplified through an Aux. Encoder Input for 1V Sinusoidal Enc. and an Incremental Encoder Output interface, ensuring seamless feedback connectivity.
