RAC 2.3-200-460-A00-Z1

The Bosch Rexroth Indramat RAC 2.3-200-460-A00-Z1 from the RAC Spindle Drive Controllers series is a high-performance AC main spindle drive controller designed for numerically controlled machine tools. It accepts a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, ±15%, or 3 x AC 460 V, making it compatible with global three-phase supplies. This Device Type provides a Rated Current of 200 A and features a robust internal blower/Cooling system with a built-in fan to maintain optimal operating temperature. The controller’s Speed Command interface uses an analogue ±10 V set-point for precise spindle speed regulation.

The RAC 2.3-200-460-A00-Z1 integrates a Series 2, Version 3 hardware platform with an Additional Bleeder circuit, enhancing DC-link stability under dynamic load changes. Connectivity is simplified through a 9-pole Interface Terminal X4, while the design omits an additional encoder input for streamlined installation. The absence of an Additional Encoder Input reduces wiring complexity and avoids potential signal conflicts in compact control cabinets. Modular expansion is supported via a link circuit connection and a dedicated control voltage bus, facilitating integration into existing CNC environments.

With its proven construction and international compatibility, this controller excels in applications requiring high continuous power and reliable deceleration through direct current braking. Its precise analogue speed set-point and compact form factor make the RAC 2.3-200-460-A00-Z1 ideal for main spindle drives in milling, turning, and grinding machines. Ready for immediate mounting with a complete mechanical fitting kit, this controller delivers dependable spindle performance across diverse industrial climates.
