The Bosch Rexroth R911269660 (RAC 3.5-150-460-A0D-W1-220) main spindle drive controller boasts high rigidity and an extensive speed range with persistent power. It includes an internal position control loop, which can adjust with either motor or additional spindle feedback. Cooling is facilitated by air circulation both within and surrounding the control cabinet. The programming component facilitates replacement on a new controller if necessary. This versatile device is operable in a multitude of settings, from warm to cold environments, provided average relative humidity stays under 70%. The controller lacks water and penetration protection and the control cabinet has an IP 54 protection level. Additional features include a 16-bit parallel position setpoint digital interface, power dissipation based on workload, minimised cabling, and standard, easily accessible electrical connections. The controller operates effectively up to a maximum ambient temperature of 55°C with 80% data reduction. During transport, the device must not be tipped, dropped or exposed to dampness or excessive weight. Only authorised personnel should carry out repairs, ensuring all screws are removed before removal. It comes with a one-year warranty and is delivered in military-grade foam packaging for optimal protection.
