Product Description:
The RAC 2.3-250-460-D00-W1 is an AC main spindle drive controller manufactured by Bosch Rexroth Indramat within the RAC Spindle Drive Controllers series. Designed for high-power machine tool axes, the unit converts a facility three-phase supply into controlled amplitude and frequency for spindle motors. It occupies the main spindle channel in a multi-axis rack, enabling closed-loop control that keeps rotational speed stable during heavy cutting, tapping, or grinding operations in automated production lines. This operating role supports consistent spindle response when load conditions change during demanding machining cycles.
Its power stage delivers a continuous output of 250 A, supplying sufficient current to large spindle motors without external parallel drives. The input range of 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V allows the same unit to run on European or North American plant voltages. A 16-bit parallel digital speed command bus connects directly to numerical controls so that command changes are transferred in a deterministic format. Parameter and diagnostic wiring is concentrated on the X4 25-pole terminal block, which keeps interface connections grouped at one location. Thermal management relies on a built-in fan that pulls air through the heat sink fins, allowing the controller to operate where external airflow is limited.
This hardware is supplied without an additional bleeder, so regenerated energy must be handled by the standard braking resistor or returned to the DC link. It is also provided without an additional encoder input, so velocity feedback enters through the primary spindle sensor channel only. The controller belongs to design level 2 and version 3. That arrangement suits installations that use the standard spindle interface without optional expansion hardware.
