R911256105
The R911256105 (RAC 3.5-150-460-A00-W1-220) Main Spindle Drive Controller, a product of Bosch Rexroth Indramat, is specifically designed for digital control of asynchronous main spindle motors and frameless spindle motors from the same manufacturer. With the benefits of high stiffness, it's a perfect fit for numerically controlled machine tools. The device comes installed with an emergency stop and mains contactor circuits, complemented by an AS programming module. A control panel consisting of a keypad and a display is a prominent feature of the device - an essential tool for programming various parameters during commissioning.
Further specifications include a control voltage interface, motor NTC-resistor interface, motor power interface, and a direct mains interface located at the top. Environmental tolerance conforms to Class F humidity as per DIN 40 040 specifications, and it's designed to prevent entry of foreign objects over 50mm. For operation above an altitude of 1000m, note there's a decrease in the rated power and torque values. Installation is back wall-mounted using M8 screws within a sealed housing. The device is cooled by an integrated fan, operating at 220VAC and a frequency of 50/60Hz. The E1-RAC electrical connection accessories kit provides plug-in terminals for mains contactor control and motor NTC-resistor. The device offers a continuous power output of 35kW at the motor output shaft. Shipping is facilitated through partners such as UPS.
