Product Description:
The RD51.1-5N-110-L-DL-FW is a drive controller manufactured by Bosch Rexroth Indramat and belongs to the RD 500 Drive Controllers series. The device converts fixed mains power into variable output for asynchronous motors, enabling speed and torque regulation in automated conveyors, fans, and processing equipment. Mounted inside a control cabinet, it functions as the central power stage that links PLC commands to motor terminals during continuous industrial duty. This arrangement allows the motor to respond smoothly to changing process demands without requiring direct manual adjustment at the load.
Rated output is 110 kW, indicating the maximum mechanical power the inverter can deliver under nominal conditions. The supply section is a converter 3 × AC, so it rectifies three-phase line voltage before synthesizing a variable AC waveform. That input must lie within the 500 V range used by this model for safe operation. Speed modulation is performed with U/f curve control, which keeps voltage and frequency proportional so magnetic flux remains stable as load conditions change. Thermal energy generated by the power semiconductors is removed through forced air cooling, with an integrated fan directing airflow along the heat sink to keep internal temperatures within operating limits. This cooling method supports steady operation during prolonged runtime in enclosed industrial cabinets.
The unit is delivered without a built-in brake chopper, so external chopper circuitry or a braking resistor must be added when regenerative energy is expected. Hardware classification follows design generation 1, so connector placement and parameter numbering match other first-generation RD controllers. Field wiring is grouped on a NAMUR terminal strip, which helps organize control connections in a consistent layout. For long motor leads, the drive provides feedback of cable damping, allowing the control board to compensate for reactive losses and sustain commanded torque accuracy across extended cable lengths. The linked 24 V stand-by input keeps status circuits energized when the main bus is isolated, which helps preserve control visibility during service conditions.
