RAC 2.3-200-380-A0D-W1

The RAC 2.3-200-380-A0D-W1, manufactured by Bosch Rexroth Indramat, is part of the versatile RAC Spindle Drive Controllers series designed for high-performance spindle control applications. This AC main spindle drive controller delivers precise speed regulation and torque control in demanding industrial settings. Its robust design ensures seamless integration with a variety of machine tool architectures. With a compact footprint and built-in protection features, the RAC 2.3-200-380-A0D-W1 is engineered for both new installations and retrofit projects.

Engineered as an AC Main Spindle Drive Controller, the unit accepts a Rated Connection Voltage of 3 x AC 400 V, 50-60Hz and furnishes a continuous Rated Current of 200 A for sustained high-speed operation. Speed reference is provided via an Analogue (+/- 10 V) Speed Command input, while a Digital position set-point (16 bit parallel) acts as an Additional Interface for synchronization with external controllers. Cooling is managed by an Internal Blower / Built-in fan, ensuring thermal stability under heavy load cycles. The controller is equipped without an Additional Bleeder and without an Additional Encoder Input, simplifying wiring and reducing component count. Service technicians appreciate the standardized Interface Terminal X4 with 9 poles for easy field wiring. This Version 3 of Series 2 maintains a consistent control algorithm across the RAC family.

Integration into automated production lines is streamlined through its standardized mounting and control interface, reducing commissioning time and engineering overhead. The rugged construction and fan-assisted Cooling ensure reliable operation in harsh environments, while the precision speed command and high current capability deliver consistent machining quality. Ideal for milling, grinding, and turning centers, the RAC 2.3-200-380-A0D-W1 offers dependable performance and long-term system availability.
