Product Description
The RAC 2.2-250-380-A0D-W1 is the central spindle drive controller for asynchronous spindle motor operated as a digitally controlled drive and second motor feedback machine tool. The unique machine tool is manufactured by Bosch Rexroth. This RAC 2.2 version has 400A current rating and uses 3*AC400V/50-80Hz connection voltage. This new tool has high stiffness and a broad range of continuous power. The internal position control loop of the product is closed using motor feedback or spindle feedback. The main spindle drive is proficient in precise control loop servo-axis; it can be controlled effectively even at low speed.
The RAC2.2 Spindle has a built-in fan for cooling in the control cabinet where the Spindle is mounted. It can be cooled with gentle inside and outside airflow. The central controller can be connected to a three-phase supply integrated with the main contractor and emergency stop switch. The Set-speed point for digital interfaces features +/-10V analog, 16 bit parallel to PLC controllers with the longest circuit with 9 poles connecting terminal and low set points. In RAC 2.2 design, Additional encoder inputs are also available for connecting the Spindle for the internal controller. The ambient temperature range for spindle drive of +5 to +45 °C is optimized for efficient operation. The RAC 2.2 effectively operates in a humidity-free room in a cold and dry climate.
The maximum 1000 meters altitude required for perfect torque and rated power. If the height increases from the full range, energy and torque decrease. It has a protection class of IP 10 acc. in observance to EN 60529 (DIN VDE 0470) specifications Inside the control cabinet. At the delivery time, the fitting kit M2-RAC 2.2 contains all mounting parts such as gaskets and screws. The external and internal power depends on the workload of the machine. The spindle drive controller should install at a position that condensation water does not fall on it. Use a standardized cabinet for mounting and well airing. The RAC 2.2-250-380-A0D-W1 central spindle drive controller can be delivered internally through shipping agents like FedEx. The RAC 2.2-250-380-A0D-W1 comes with a warranty period of one year.
