Internal Product Review
RAC 2.2-200-380-AP0-W1 is an AC main spindle drive controller with a 200 A rated current. Internal blower cooling and a high-resolution INDRAMAT encoder support stable thermal management and precise spindle feedback. Analog ±10 V speed command is a strong advantage for straightforward integration into established spindle control architectures.

Product Description:
The RAC 2.2-200-380-AP0-W1 spindle drive controller is produced by Bosch Rexroth Indramat and belongs to the RAC Spindle Drive Controllers series. As a spindle drive controller, it governs the torque and speed of high-performance machine-tool spindles, translating reference commands from the CNC into regulated three-phase output for the motor. This unit integrates power electronics, feedback handling, and internal cooling into a single housing so it can be installed in electrical cabinets that support automated milling, turning, or grinding centers.
In operation, the controller connects directly to a plant mains supply of 3 × AC 400 V, 50–60 Hz, and it can deliver up to 200 A of continuous output current to the spindle motor, matching the demands of large-frame asynchronous or synchronous drives. Thermal energy generated by the power stage is dissipated through an internal blower cooling system, allowing cabinet mounting without external heat exchangers. Speed reference arrives as an analog ±10 V speed command, which the control electronics use to set inverter frequency. Field wiring for power, control, and diagnostics connects through the X4 9-pole terminal, which provides a fixed connection point for low-level signals. The unit is part of series 2, which keeps the layout and pin assignments consistent within this product line.
A high-resolution INDRAMAT encoder interface is supported, and the module also provides an additional spindle encoder input so the control loop can compare motor-mounted feedback with external position transducers for improved contour accuracy. The unit is an AC main spindle drive controller, so its logic and power stages are synchronized to the mains phase. The product is version 2. The design omits an additional bleeder resistor, so regenerative energy must be handled by the DC link or an external braking module. This arrangement supports closed-loop velocity and position control for high-speed machining without auxiliary cooling equipment or proprietary signal converters.
