RAC 2.3-200-380-D0I-W1
RAC Spindle Drive Controllers
RAC 2.3-200-380-D0I-W1, Bosch Rexroth Indramat, RAC Spindle Drive Controllers. This AC main spindle drive controller delivers robust performance in heavy-duty machining environments. The unit accepts a Rated Connection Voltage of 3 x AC 400 V, 50-60Hz and provides a continuous Rated Current of 200 A through an efficient Internal Blower / Built-in fan cooling system. With a compact design optimized for cabinet integration, it supports straightforward installation and service.
Equipped with a 16-bit parallel Digital Speed Command interface, the controller achieves precise spindle acceleration and deceleration profiles. A 10V Speed Set-Point input allows fine analog tuning, while the Interface Terminal X4 (25 poles) groups power, signal, and encoder lines for simplified wiring. The unit’s Additional Interface includes an Incremental encoder output for closed-loop feedback, and its design omits any Additional Encoder Input or Additional Bleeder to reduce component count and failure points. Internal firmware (Version 3, Series 2) provides standardized parameter sets and diagnostic routines via the drive bus connection.
Integration into CNC systems is seamless, leveraging industry-standard electrical interfaces and control logic. The rugged construction and fan-based Cooling ensure stable operation under continuous loads, maximizing uptime. Ideal for high-precision milling, drilling, and turning, the RAC 2.3-200-380-D0I-W1 enhances spindle reliability and simplifies machine tool architectures.
