The R911201102 (RD52.1-4N-160-R-V1-FW/S109) is a field-oriented vector control device from Bosch Rexroth intended for synchronous and induction motor drive systems. This unit is a converter without a built-in brake chopper, providing a rated power of 160 kW and supporting a nominal connecting voltage of 3 x AC 380-480 V. Peak power output is 257 kW for 60 seconds at 4 kHz. The device utilizes liquid cooling with an internal pump. The operating temperature should not exceed 50°C, and the rated power decreases by 2.5% per degree Celsius above this threshold. Installers must observe safety regulations, ensure all grounding is intact, and prevent electrostatic discharge by minimizing contact with electronic boards. The housing can become hot during operation and the unit is not designed for submersion in water. After shut-off, a minimum discharge period of 30 minutes is recommended to allow capacitors to discharge.
