RAC 2.2-250-460-D00-W1

The Bosch Rexroth Indramat RAC 2.2-250-460-D00-W1 from the RAC Spindle Drive Controllers series is an advanced AC Main Spindle Drive Controller designed for demanding machining applications. This controller accepts a Rated Connection Voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V and delivers a continuous Rated Current of 250 A to high-performance spindles. Housed in a rugged enclosure with an Internal Blower / Built-in fan for Cooling, it ensures stable operation under full load. The unit is supplied Without additional bleeder and Without additional encoder input, simplifying installation and reducing component count.

Designed for digital precision, the drive’s Speed Command input is Digital (16 bit parallel) and integrates a Speed Set-Point of 10V, enabling exact spindle control and rapid response to setpoint changes. Connectivity is ensured via an Interface Terminal X4, 25 poles, accommodating all power and signal lines in a single robust connector. The drive’s internal logic conforms to Series 2, Version 2 specifications, guaranteeing compatibility with existing RAC infrastructure. Its streamlined feature set focuses on core spindle control functions, making it ideal for retrofits and new OEM builds alike.

With its compact form factor and straightforward terminal layout, the RAC 2.2-250-460-D00-W1 simplifies cabinet design and maintenance. The integrated fan cooling and elimination of extra encoder or bleeder modules reduce overall system complexity and cost. This spindle drive controller offers a reliable, high-current solution for CNC mills, lathes, and multi-spindle machining centers where precision and uptime are essential.
