Product Description:
The RAC2.1-200-415-A00-W1 is a spindle drive controller produced by Bosch Rexroth Indramat and released within the RAC Spindle Drive Controllers series. As an AC main spindle drive controller, it regulates the torque and speed of high-performance spindle motors used in machining centers and other automated cutting equipment. By converting three-phase mains power into a controlled output for the motor inverter, the unit forms the central axis interface between numerical control commands and mechanical spindle motion in industrial automation. It is intended for applications where stable spindle response is needed during acceleration, constant-speed cutting, and programmed speed changes throughout a machining cycle.
The controller operates from a nominal input of 3 x AC 415 V and is designed to supply up to 200 A of continuous output current, allowing direct connection to large synchronous or induction spindles. Speed reference enters the drive through an analog +/-10 V setpoint channel, so external CNC hardware can impose precise velocity profiles without digital fieldbus overhead. Internal heat is removed by a built-in fan, which supports thermal control inside the housing during sustained operation. Functionally, the device is an AC main spindle drive controller, meaning it is intended for spindle-axis current regulation and protective monitoring rather than for standard feed-axis duty.
The control layout is kept simple because the unit ships without an additional encoder input, so feedback processing relies on the standard spindle encoder connected through the standard port. Likewise, there is no additional interface, which keeps the connection layout limited to the primary control and feedback paths already provided on the unit. Energy returned during rapid deceleration is handled by the internal power section, so there is no external bleeder when regenerative demand remains within the drive’s intended operating range. This arrangement reduces the number of supporting components in the panel and keeps the drive focused on core spindle-control functions.
