RAC 4.1-300-460-A00-W1
RAC Spindle Drive Controllers
The Bosch Rexroth Indramat RAC 4.1-300-460-A00-W1 drive from the RAC Spindle Drive Controllers series is an advanced AC Main Spindle Drive Controller designed for precision spindle regulation. It accepts a rated connection voltage of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V and delivers a rated current of 300 A. Cooling is managed by an internal blower / built-in fan to ensure stable thermal performance. The unit supports a speed command via analogue (+/- 10 V) input and features a 9-pole X4 interface terminal. This version (series 4, version 1) omits an additional bleeder and additional encoder input for streamlined operation, making it ideal for high-demand machining environments.
