The R911256148 (RAC 2.3-200-460-LP0-W1) is a drive controller in the RAC 2 series from Bosch Rexroth, designed to digitally manage Indramat 2AD asynchronous main spindle motors and 1MB frameless spindle motors. Most suited for CNC machines, this controller offers high stiffness and consistent power across a wide speed range. It is equipped with an internal position control loop, either via motor or optional spindle feedback, ensuring precise spindle positioning. It operates on a 3-phase power supply and includes a mains switch or contactor, and emergency stop circuit. The R911256148 (RAC 2.3-200-460-LP0-W1) supports energy regeneration during braking, and can halt the main spindle even during power outages. Cooling can be achieved through circulating air inside or outside without any accessories. The current rating is 300A and it has a SERCOS interface for speed setting. It does not include an additional bleeder or interface but does come with an internal fan. The product includes a one-year global warranty from Indramat USA.
