RAC 2.3-250-380-A0S-W1

The Bosch Rexroth Indramat RAC 2.3-250-380-A0S-W1 is a robust spindle drive controller from the RAC Spindle Drive Controllers series designed for high-performance machining applications. As an AC Main Spindle Drive Controller, it operates on a Rated Connection Voltage of 3 x AC 400 V, 50-60Hz and delivers a Rated Current of 250 A, providing precise power management for demanding spindle systems. This controller’s primary function is to regulate spindle speed and torque in CNC and milling operations, ensuring smooth acceleration and reliable performance under varying load conditions.

In terms of technical specifications, the RAC 2.3-250-380-A0S-W1 is equipped with an Internal Blower / Built-in fan cooling system to maintain optimal operating temperatures even during extended use. Communication is facilitated via a Serial interface RS 232-C, while control signals are handled through an Analogue (+/- 10 V) Speed Command input. The device features an Interface Terminal X4, 9 poles for I/O connections and belongs to Series 2, Version 3, reflecting its evolution for enhanced reliability and compatibility with modern automation setups. Its streamlined design omits an additional encoder input and bleeder, reducing complexity in installations where these functions are managed externally.

Additional features of the RAC 2.3-250-380-A0S-W1 include its straightforward integration with existing spindle systems and industrial networks, thanks to the standard RS 232-C port and analogue speed reference. The absence of an Additional Bleeder and Additional Encoder Input simplifies configuration in setups that use centralized brake and feedback modules. Certified to operate under industrial voltage and thermal conditions, this controller exhibits high durability and operational efficiency. In industrial applications, the Bosch Rexroth Indramat RAC controller enhances machining precision, reduces downtime through reliable thermal management, and streamlines system architecture for cost-effective integration.
