R911256127
The R911256127 (RAC 2.3-200-380-A0I-W1), produced by Bosch Rexroth Indramat, is an innovative digital spindle drive controller, weighing approximately 122kg. This motor drive is recognized for its wide operating speed range, high stiffness, and persistent power dissipation. It includes an incremental encoder output interface for positional CNC control. Its additional heat dissipation feature involves an internal built-in fan that eliminates the need for an external bleeder. The device operates on a voltage connection of 3 x AC 400V, spanning 50-60Hz, with a deviation of -15% to +10%.
The R911256127 (RAC 2.3-200-380-A0I-W1) operates at optimal capacity in an ambient temperature ranging from 5 to 45 degrees, when run at regular equipment rating. This device, without an additional encoder input, features a diagnostic displaying screen on its control panel. For storage and transport, the permissible temperature is from -30oC to +85oC, with an insistence on a dry and dust-free environment. With respect to the motor shaft, its peak power output stands at 55 kW. Adherence to the DIN 40 040 standards places the R911256127 (RAC 2.3-200-380-A0I-W1) in humidity class F. The protection rating is set according to EN 60 529 standards at IP 10. All safety measures like optimal airflow, maximum permissible overpressure and manufacturer’s wiring plans should be observed.
