The Bosch Rexroth main spindle drive controller MPN R911266093 (RAC 3.5-150-460-D00-W1-220) is engineered for numerically controlled machinery, offering a rated current of 150 A and employing an internal position control loop with resolution to 1/4,000,000 of a revolution. The device operates on control electronics supplied with AC 230 V, 50-60 Hz and main power connection at 3 x AC 400–460 V, 50 Hz ±15%. It incorporates an integrated emergency-stop switch, main contactor, and a 16-bit parallel digital speed set-point interface (X4, 25 poles) for PLC integration. The unit lacks additional encoder input, interface, or bleeder and provides IP10 protection against objects larger than 50 mm. Cooling is achieved via a built-in internal blower. It is compatible with class F humidity requirements and includes a mechanical fitting kit.
