Product Description:
The RAC 2.2-200-460-D00-W1 is an AC main spindle drive controller manufactured by Bosch Rexroth Indramat for the RAC Spindle Drive Controllers series. Installed inside a machine-tool cabinet, it links a CNC control to the spindle motor by converting numerical velocity commands into regulated three-phase power. It acts as the power interface between numerical control commands and the electrical demands of the spindle motor during changing load conditions. The unit governs torque and speed so the spindle maintains constant cutting conditions during drilling, milling, or grinding, which helps support repeatable part quality and steady surface finish in automated machining lines.
The controller accepts a line supply of 3 × AC 400 V at 50 Hz ±15 % or 3 × AC 460 V, making it compatible with common European and North American power systems. Its power stage can provide a continuous drive output of 200 A, which suits large-frame spindles that require strong acceleration. That current capacity helps the spindle recover speed quickly after heavy cuts and tool entry. Component temperatures are managed by an internal blower, so no external ducting is required to sustain the rated load. Velocity references are delivered through a digital 16-bit parallel channel, giving fine command resolution across the full speed range. Control wiring converges on connector X4, 25 poles, which groups the interface signals at one cabinet connection point and keeps low-level command signals organized within the control section.
During deceleration the unit is supplied without an additional bleeder, so regenerated energy must be handled by the motor or by an external resistor bank selected for the application. Feedback expansion is also omitted; it is supplied without an additional encoder input because standard spindle sensor lines already enter the drive. The controller is Series 2, and the logic board is Version 2. This configuration keeps the drive focused on standard spindle control functions without adding optional feedback hardware.
