The Bosch Rexroth R911245503 (RAC 4.1-300-460-API-W1) is a high-functioning motor drive controller, ideal for controlling automated control elements such as mills, routers, and lasers. With a built-in automatic position control loop, it accurately controls the lowest of speeds. It features a speed set-point via a 0 to 10V connection on typical NCs, along with an additional encoder for adapting spindle feedback and extra interface via an incremental encoder. The controller's continuous output rates at 93kW and a feedback output of 60kW. The R911245503 (RAC 4.1-300-460-API-W1) includes cooling components for adequate ventilation, with optimum operating temperature at 40°C. Its design allows heat dissipation through air slits and the heat sink, enabling automatic cooling from outside the cabinet. The controller requires a dry, dust-free storage environment and careful handling during transport. Included in the purchase is a one-year global warranty from Indramat USA.
