RAC 2.3-250-380-L00-Z1, Bosch Rexroth Indramat, RAC Spindle Drive Controllers series delivers precision and power in a compact controller design. This AC Main Spindle Drive Controller integrates seamlessly into high-performance machining centers and rotary tables, providing reliable speed regulation and torque control. A built-in fan ensures continuous thermal management, while the robust enclosure supports industrial environments. Enhanced safety and ease of maintenance are achieved through modular design and straightforward wiring interfaces.



Engineered for demanding spindle applications, the unit accepts a Rated Connection Voltage of 3 x AC 400 V, 50-60 Hz and sustains a continuous Rated Current of 250 A. The Internal Blower / Built-in fan cooling system, paired with an Additional Bleeder, expels heat efficiently under peak-load conditions. Command signals flow via the Speed Command SERCOS interface, while the Speed Set-Point analogue input (10 V) provides fallback compatibility with legacy systems. Connectivity is further enhanced by an Interface Terminal using X4 optical waveguides, eliminating electromagnetic interference for precise data transmission. The controller ships in Version 3 of Series 2, tailored for standardized rack mounting. Despite omitting an Additional Encoder Input, the integrated SERCOS protocol delivers high-resolution feedback control.



Integration into multi-axis configurations is simplified by its modular terminal layout and coherent parameter management tools, reducing commissioning time. Long-term reliability is assured by the blower-cooled power stage and the protective bleeder circuit, which safeguard bus capacitors against voltage spikes. Ideal for CNC spindles and rotary indexers, the RAC 2.3-250-380-L00-Z1 maximizes throughput and uptime in high-speed machining and advanced manufacturing environments.
