The Bosch Rexroth R911203499 (RS51.1-4G-014-L-V1-FW/S117) is a drive control device engineered for automation environments, specifically supporting high-speed grinding spindles. Key features include compatibility with both induction and synchronous motors, AC drive conversion, and integrated regenerative braking with built-in brake chopper and resistor. An embedded interference suppression filter reduces electromagnetic disturbances, while forced air cooling and rear-mounted power sections enhance thermal management. Control functions include XOR, PI, PID, flip flop, and D latch, supporting precise speed and positioning. The unit operates with a nominal connecting voltage of 3 × AC 380‑480 V and offers 14 kVA rated power. RS232 and RS485 serial interfaces are provided for external system integration.
