RD43.1-4R-185-F-NN-FW

The Bosch Rexroth Indramat RD43.1-4R-185-F-NN-FW from the RD 500 Drive Controllers series by Bosch Rexroth Indramat delivers a robust 185 kW rated output at 3-phase AC 400 V and accepts a 380-480 V supply voltage. Engineered without a brake chopper device variant, it relies on a cooling mode of forced air cooling with integrated liquid circulation to maintain optimal thermal performance. The drive features an enclosure to safeguard against solid objects larger than 50 mm. Operators can manage operations via a four-line display unit and six pressure-sensitive keys on the integrated control panel.

Designed for demanding industrial environments, the RD43.1-4R-185-F-NN-FW incorporates an internal fan and heatsinks to regulate internal temperatures through forced ventilation. Its liquid circulation system supplements cooling capacity to handle sustained high loads. For expanded functionality, the drive supports multiple master communication interfaces including SERCOS, CANopen, Profibus, and Interbus S. The controller’s firmware module is ordered separately, enabling tailored configurations to suit your application demands.

The permissible operating ambient temperature ranges from 0 to 45 °C, ensuring reliable performance when housed within a suitable cabinet rated at least IP54 protection class. A comprehensive one year warranty from Wake Industrial provides peace of mind and global shipping availability. With its balanced combination of power density, versatile communications, and advanced cooling architecture, the RD43.1-4R-185-F-NN-FW is an ideal choice for precision servo motor control in high-intensity production systems.
