The product in focus is the Bosch Rexroth R911244442 (RAC 2.2-250-460-A0I-Z1) spindle servo drive, a part of their RAC 2 drive controller series. This device is designed to efficiently control spindle motors with its internal feedback position control loops and its capacity to control the spindle as a c-axis. Rated at 3x400 Volts AC at 50Hz and 3x460 Volts AC at 60Hz, this drive can be directly linked to a three-phase power supply for a wide power range and has a 400 Amps current rating. Some important features include direct current braking, standard cables for easy connections, and an additional bleeder. The drive is built to function within a temperature range of 5 to 45 degrees Celsius and includes an internal fan for heat dissipation. Additionally, it allows on-site drive parameter configuration through a programming module, comes with an incremental encoder output, an emergency stop switch, and does not offer water protection.
