R911256087
The Bosch Rexroth Indramat's R911256087 (RAC 3.5-100-460-AP0-W1-220) is an exceptional drive controller part of the RAC 3 series. Powered by a voltage supply rate of 3x AC 380-480V/50-60Hz with a current of 10A, the device features an internal closed loop for precise spindle movement control. This is further advanced with an additional encoder input that supports the creation of a second motor or spindle feedback, thereby enhancing the device's efficiency in closing its operation loop.
The unique feature of the R911256087 (RAC 3.5-100-460-AP0-W1-220) is its analogue (+/-10V) type speed set point, which efficiently processes information and operates at a faster pace, courtesy of its low bandwidth consumption. It uses -/+10 volts, allowing for optimal correlation with CNC controls. The only downside is the absence of an additional interface, limiting certain features. To maintain its seamless functionality, the device is equipped with a robust fan, cooling both inside and outside of the control cabinet to keep the temperature in check. Vital components such as the emergency stopper and main contactor circuits are included in its design to support diversified operations.
