R911256099
The R911256099 (RAC 3.5-150-460-A0I-W1-220) is a main spindle drive controller crafted by Bosch Rexroth Indramat. Its distinct features include an internal position control loop and broad space range. The drive controller functions at an optimum current type of 150A and a nominal voltage supply of 3 x AC 380 and 460V at a frequency range of 50/60Hz, making it perfectly suitable for numerically controlled machine tools. The controller brings precise rotor position resolution of up to 1/4 000 000th of a revolution. A unique addition to this controller is an embedded emergency-stop circuit and an optional incremental encoder output interface for position control with C-axis operation during tasks like screwing, tapping.
Ideal operation conditions for R911256099 (RAC 3.5-150-460-A0I-W1-220) range from +5 to +45 degrees Celsius and it should not function above 55 degrees Celsius. It's designed to operate at a maximum altitude of 1,000 meters above sea level. The controller is equipped with an integrated fan for cooling, making it suitable for humid environments, as long as humidity is within the F range according to DIN 40 040 standards. The controller's design offers protection against the intrusion of objects larger than 50mm. It has a separate supply voltage rate for control electronics set at AC 220V/50-60Hz. It should be noted that this controller does generate heat during operation.
