The Bosch Indramat R911256108 (RAC 3.5-150-460-L00-W1-220) is an AC main spindle drive controller rated for 150 A with a connection voltage of 3 x AC 460 V, 50/60 Hz. It includes integrated emergency circuit breakers, a primary contactor, and supports control electronics rated at AC 230 V, 50-60 Hz. The unit operates using a SERCOS interface for speed commands via optical waveguides at terminal X4, with a speed set-point of 10V, and does not provide additional encoder input or bleeder. Cooling is managed by an internal blower with a built-in fan, with alternatives for external air or hose-fed cooling requiring separate accessories. The integrated AS programming module supports site-specific parameterization and duplication of settings across machines. Performance considerations should account for installations at altitudes exceeding 1000 m or environments with humidity above 70%. The unit provides self-diagnostic capability, shutting down in the event of a fault and retaining parameters for simplified replacement.
