Product Description:
The RAC 2.2-150-460-A0I-Z1 is an AC main spindle drive controller built by Bosch Rexroth Indramat within the RAC Spindle Drive Controllers series. It converts fixed-frequency mains power into regulated three-phase output for machine tool spindles, allowing controlled speed during cutting, grinding, and drilling operations. This type of drive is used where the spindle must respond smoothly to changing load conditions while maintaining commanded speed during material removal. Designed for installation beside axis drives in a common cabinet, the unit manages the high rotational energy of the spindle channel and exchanges speed-related signals with external CNC logic.
The power stage accepts 3 x AC 400 V, 50 Hz, +/-15% or 3 x AC 460 V, so it can connect directly to common plant mains in Europe and North America without an external transformer. Under continuous load, the controller delivers 150 A, which supports large spindle motors that need substantial startup torque and stable running current. Thermal management is provided by a built-in fan that moves air across the heat sinks. This airflow supports stable operation when the spindle channel is producing sustained torque. Command and diagnostic wiring terminates at the X4 terminal strip with 9 poles, and spindle speed is commanded through an analog +/-10 V command input that matches standard CNC analog outputs.
For deceleration duty, the unit includes an additional bleeder that dissipates regenerated energy into a paired resistor bank. This helps the drive handle energy returned by the spindle when speed is reduced quickly or when a heavy rotating load is brought down in a controlled way. Motor feedback can be passed through the drive to downstream controls, but this model is supplied without an additional encoder input. Instead, it uses an Incremental encoder output to mirror the motor signals to the CNC. The drive is Series 2 and uses Version 2 for this production release.
