The Bosch Rexroth R911293919 (RAC 3.5-200-460-D0I-W1-220) Spindle Drive Controller, from the distinguished RAC series, is engineered for digital command of both frameless and asynchronous spindle motors. Designed with uncompromised stiffness, position control, and a wide speed range, it boasts an independent positioning feature post-signal reception. Integrated with emergency-stop and mains contactor circuits, the device further enhances safety. The controller efficiently cycles back energy from braking actions into the three-phase power supply. A built-in fan provides cooling, ensuring optimal performance at a control voltage of 230VAC +/-10% at 50/60Hz frequency. For fitting ease, the controller comes with two screw-on covers and requires installation inside a control cabinet. Moreover, it has a 16-bit parallel digital speed set-point interface for effective PLC connections. Functions optimally between 5°C to 45°C with an IP 10 protection class, adhering to DIN VDE 40 0470/EN 60 529 specifications. Lastly, it has a one-year warranty from Indramat USA and is available for global shipping.
