It also features an emergency stop function that immediately halts or decelerates connected drives in the event of internal electronic malfunctions. Furthermore, its highly responsive control increases accuracy in rotor position management, and its wide speed range doesn’t compromise power output, ensuring steady performance even with changing speeds. This makes the R911232713 (RAC 2.2-250-380-A00-W1) an ideal drive controller for the main spindle drive in CNC machines.\u003c\/span\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Refurbished","offer_id":51690417258797,"sku":null,"price":10526.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/RAC_Spindle_Drive_Controllers__e07028ae-57a0-4f84-b345-4ea3ed794e82.webp?v=1757878872"},{"product_id":"r911256106","title":"R911256106","description":"\u003cspan\u003eThe R911256106 (RAC 3.5-150-460-A00-Z1-220) main spindle drive controller is a product by Bosch Rexroth Indramat, part of their RAC series. This controller utilizes a bleeder to effectuate the main spindle's cessation during a mains failure. Integral to the product is a ventilation system that facilitates air circulation within the control cabinet. Installation must proceed with the use of lifting equipment, and the programming module should be affixed to the left of the device's front panel before commissioning. It is crucial this is completed prior to the initiation and subsequent commissioning of the device after the safety guards are installed.\n\nMoreover, connectors must be securely tethered post-commissioning, and the panel display is useful for fault detection. Storage and transportation conditions recommended range between -30°C and 85°C in a dry, dust-free environment. The device comes with attachable covers for the fan housing and heat sink, enhancing its maintainability. Powered by a supply voltage of 3 x 380 to 460VAC, it has an analog speed setpoint bearing a +\/-10V rating. Operated by a microprocessor, the drive encompasses software with both drive and application associated parameters, all impacting its operational characteristics. The programming module comprises a rating plate providing essential details such as type, software designations, motor and controller type information, and date of parameter setting.\u003c\/span\u003e","brand":"Bosch Rexroth Indramat","offers":[{"title":"Unused Surplus","offer_id":52194298298669,"sku":null,"price":16410.36,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":51689477505325,"sku":null,"price":14918.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/RAC_Spindle_Drive_Controllers__ca03685f-9ee7-4e8f-965e-0e4c42cbaadd.webp?v=1757703826"},{"product_id":"r911259634","title":"R911259634","description":"\u003cspan\u003eBosch Rexroth Indramat's R911259634 (RAC 3.5-200-460-L00-Z1-220) spindle drive controller, featuring a supplementary bleeder, provides effective braking under mains voltage failure conditions. The control electronics requires a rated supply voltage of 220VAC and a frequency ranging between 50-60Hz. Installation necessitates an adequately ventilated control cabinet, and a lifting device for proper insertion of the controller. A dedicated socket for the programming module is situated on the device's lower left front panel, which must be connected and secured prior to commencement of operation.\n\nThe drive controller's design requires it to incorporate the ground connection of the motor it's managing. An in-built display aids in diagnosing faults, and the controller brakes until it reaches a standstill mode when a fault is detected. Repairs should be conducted while the controller is switched off, standstill, and only by certified professionals. Ensure the safety guard is properly installed post connection and prior to powering up. The left inside housing holds a type plate and the controller operates with a 200A current rating. The controller's parameters and software are found within the programming module.
