RAC 2.3-200-380-A0I-Z1

The Bosch Rexroth Indramat RAC 2.3-200-380-A0I-Z1 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller designed for precision machining applications. It operates on a Rated Connection Voltage of 3 x AC 400 V, 50-60Hz and delivers a robust Rated Current of 200 A for demanding spindle loads. This version features an Internal Blower / Built-in fan cooling system to maintain optimal temperature under continuous duty. Engineers will appreciate the integrated Additional Bleeder function for safe discharge of stored energy and the modular Series 2 Version 3 hardware platform.

Installation and integration are streamlined through the Interface Terminal X4, 9 poles connector, providing reliable power and signal routing. Motion feedback is handled via the Additional Interface: Incremental encoder output, while the drive omits any Additional Encoder Input, simplifying wiring for standard servo loops. Control is executed by a precision Analogue (+/- 10 V) Speed Command input, ensuring smooth acceleration profiles. The controller's compact form factor aligns with industry-standard footprints, delivering straightforward panel mounting and service access.

Built-in diagnostic routines monitor thermal status and current draw, leveraging the drive's rugged construction and proven cooling methodology. Maintenance intervals benefit from the internal airflow design that prevents dust accumulation on heat sinks and power semiconductors. Overall, the RAC 2.3-200-380-A0I-Z1 offers dependable spindle speed regulation, rapid commissioning, and compatibility with a wide range of CNC platforms, making it an ideal choice for high-precision milling and drilling operations.
