Product Description:
The RD51.1-4B-007-L-NN-NN-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It regulates the voltage and frequency delivered to three-phase induction motors used in automated conveyor lines, mixers, and fluid-handling skids. By providing pulse-width-modulated output matched to process demand, the unit helps maintain commanded shaft speed while reducing unnecessary motor loading. It communicates with higher-level PLCs through hardwired control terminals.
The controller includes a built-in brake chopper that routes regenerated energy to an external resistor and prevents DC-link overvoltage during fast stops. Motor excitation is set with U/f curve control, which helps maintain constant flux so torque remains available at low frequencies. Internal thermal management relies on forced air cooling, and an integral fan pulls air across the heat sink to keep semiconductor junction temperatures within limits. Conducted electromagnetic noise is reduced by an integrated mains filter, which removes the need for a separate line reactor in most panels. The inverter can deliver up to 7.5 kW of mechanical power, supporting midsize pumps, fans, and indexing machines in continuous-duty service.
This model is design generation 1 and is supplied as a converter 3 × AC package, so it rectifies three-phase input power before inverting it for motor use. The permissible input span is 380 to 480 V, allowing the same unit to operate on both 400 V European and 460 V North American power systems, and it withstands line fluctuations of ±10 % without derating. That input range supports use on common industrial power networks. Stable input conditions help the controller maintain consistent braking behavior, cooling airflow, and electromagnetic compatibility during speed changes and load swings.
