RAC 2.3-150-380-AP0-W1

The Bosch Rexroth Indramat RAC 2.3-150-380-AP0-W1 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller designed for demanding industrial applications. It operates on a Rated Connection Voltage of 3 x AC 400 V, 50-60Hz and delivers a robust Rated Current of 150 A. Built with an Internal Blower / Built-in fan cooling system, the unit maintains optimal thermal conditions even under continuous load. Precise speed regulation is achieved via an Analogue (+/- 10 V) Speed Command interface.

Integration of spindle feedback is enhanced by an Additional encoder input for spindle feedback paired with a High-resolution INDRAMAT encoder (~), ensuring accurate position and velocity monitoring. The drive’s Interface Terminal X4, 9 poles simplifies wiring and connectivity within control cabinets. This Version 3 device belongs to Series 2, offering compatibility across the RAC family for standardised installation and maintenance. Notably, the controller ships Without additional bleeder, reducing complexity for applications that do not require external discharge circuits.

Engineered for reliability and ease of commissioning, the RAC 2.3-150-380-AP0-W1 combines rugged construction with advanced control features. Its internal blower fan and compact footprint enable high-density integration in CNC machines, grinding spindles, and high-speed rotating equipment. With high-resolution feedback and analogue speed control, this spindle drive controller ensures smooth acceleration, stable operation, and precise speed tracking for a wide range of machining processes.
