Product Description:
The RAC 2.2-150-380-A0D-W1 is an AC main spindle drive controller made by Bosch Rexroth Indramat for the RAC Spindle Drive Controllers series. It governs induction or synchronous spindles in machine tools, transforming plant power into regulated output that maintains commanded speed and torque. Integrated monitoring and parameter memory allow the drive to sustain stable spindle performance during continuous machining, thread cutting, and finishing operations in automated production cells. This operating profile suits applications where spindle speed must remain consistent during load changes caused by cutting depth, material variation, or rapid deceleration between machining steps.
Electrical integration begins with a supply rating of 3 × AC 400 V, 50–60 Hz, fitting common industrial mains in Europe and North America. From this input, the inverter can continuously source 150 A, enough to accelerate heavy work-holding systems and spindle masses without requiring oversized auxiliary equipment. Heat created by switching losses is removed through a built-in fan, so the controller does not rely on external ductwork for basic cooling. The spindle controller accepts a bipolar velocity reference over an analog (±10 V) channel, allowing legacy CNC cards to command speed changes directly. Control, enable, and fault lines converge on the 9-pole X4 connector, which keeps low-voltage connections grouped in one interface.
As a hardware platform of version 2, the controller also includes a parallel bus that receives a 16-bit digital position setpoint for synchronized tapping or contour milling where speed and position must transition smoothly. The drive is supplied without an additional encoder input, so all incremental feedback connects through the primary spindle channel. It is also supplied without an additional bleeder, so regenerated energy is handled by the internal braking arrangement during controlled deceleration. This layout keeps external components to a minimum and leaves more cabinet space available for neighboring modules.
