RAC2.1-200-415-A00-W1

The Bosch Rexroth Indramat RAC2.1-200-415-A00-W1 from the RAC Spindle Drive Controllers series is a high-performance AC Main Spindle Drive Controller designed for advanced CNC applications. This controller delivers a Peak Controller Output of 55 kW and supports a Continuous Regeneration Output of 37 kW to maintain stable torque under variable loads. It also features a Peak Regeneration Output of 55 kW for efficient energy recovery during deceleration phases. The unit is specified without additional encoder input, simplifying system integration without sacrificing precision.

Engineered for demanding environments, the controller operates in an Ambient Operating Temperature Range of 5 to 45 °C and can tolerate a Maximum Ambient Temperature of +55 °C when derated to 80% output. Its safe Storage and Transport Temperature Range of -30 to +85 °C ensures durability from factory floor to field deployment, guarding against thermal stress during logistics. Altitude performance remains consistent up to Installation Altitude Tolerance of ≤ 1000 m asl, avoiding power losses in elevated installations. Mechanical support components are optimized for minimal mass: the mounting frame weighs only 2 kg and the hose cooling accessory adds 1.7 kg, while the solid chassis contributes to a total Controller Weight of 121 kg for robust stability.

With its precise regen control, this solution exemplifies efficient motor control and advanced cooling strategies intrinsic to Rexroth precision technology. Seamless integration with existing servo drives reduces commissioning time and simplifies cabling, making it a cornerstone of modern industrial drive solutions. This controller supports a broad range of spindle configurations and withstands harsh machining environments, ensuring consistent performance across diverse applications.
