Product Description:
The RAC 2.2-200-460-A00-W1 is a spindle drive controller produced by Bosch Rexroth Indramat and belongs to the RAC Spindle Drive Controllers series. Intended for machine-tool and other production equipment, the unit monitors line power and modulates stator currents so a main spindle motor follows programmed speed and torque references during cutting, drilling, or grinding cycles. By integrating the controller close to the axis, the design reduces cabling runs and supports processes that depend on fast acceleration, stable speed holding, and repeatable deceleration.
As an AC Main Spindle Drive Controller, the device accepts a three-phase supply of 3 x AC 400 V at 50 Hz with a permissible deviation of ±15%, or an alternate 460 V feed. Internally rated switching devices pass a continuous 200 A to the motor windings, so cable sizing and circuit protection must match the current demand of the application. Speed references arrive through an analog (±10 V) input, allowing simple connection to legacy numerical controls while still providing ±100% command authority. An internal blower forces cooling air over heat-producing components so the enclosure remains within safe temperature margins during sustained high-current operation.
Field wiring for logic and auxiliary functions lands on the X4, 9-pole connector, which simplifies removal during service because a single plug carries the low-level signals. Energy dissipation hardware such as a braking resistor is not included, and the unit is supplied without an additional bleeder, so regenerative power must be managed externally. Position feedback is handled through the primary spindle encoder path because the controller ships without an additional encoder input for a secondary scale. The parameter structure corresponds to version 2, matching other controllers in series 2 so that the same parameter sets and macros can be used.
