R911260063
The R911260063 (RAC 3.5-200-460-A0I-Z1-220) is a spindle controller produced by Bosch Rexroth Indramat, specifically developed to control 1MB frameless spindle motors and Indramat 2AD asynchronous main spindle motors. It features a digital input control which allows for an adjustable motor output power in the ballpark of 10-30kW. This controller ensures steady power delivery to the motor it controls for consistent performance. It possesses an automated spindle positioning feature with a closed feedback loop, enhancing its overall precision. Furthermore, the device is equipped to operate the spindle with the utmost precision in C-axis mode.
The R911260063 (RAC 3.5-200-460-A0I-Z1-220) exhibits an efficient airflow control mechanism, and it can support different cooling systems including external and internal air cooling, or hose cooling if necessary. One of its key features includes the ability to facilitate hot-programming that allows on-site commissioning. Parameters can be manually inputted through an integrated keypad on the user interface, and they are then stored permanently in a detachable programming module. Additional ports for PC connectivity are available for direct system parameter loading, an automatic PLC-reliant digital setpoint input is also featured. To guarantee optimal performance, the unit should be installed in an environment under 1000m above sea level, at temperatures below 45oC, with a humidity class of F within the cabinet.
