Product Description:
The RD51.1-4N-015-L-CF-FW is a drive controller produced by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. It governs the voltage and frequency supplied to standard induction motors, allowing precise speed regulation in conveyor lines, pumps, and other general motion tasks across automated facilities. This operating method helps the connected motor respond smoothly to process changes while maintaining stable performance during routine industrial duty.
This controller delivers a rated output of 15.0 kW and operates across a line voltage window of 380 to 480 V, so it can connect to common industrial power systems without an external step-up or step-down transformer. The front-end power stage uses Converter 3 x AC, which indicates that the unit is intended for balanced three-phase input. Motor flux is regulated by U/f curve control, which supports stable low-speed operation and predictable motor behavior under changing load conditions. Internal heat is removed by forced air cooling, and an integrated fan moves air across the heat sink to keep the power semiconductors within normal operating limits during continuous use.
The permissible supply fluctuation is limited to ±10 %, giving the drive tolerance for short-term line variation without unnecessary shutdowns. The unit operates without a built-in brake chopper, so regenerated energy from rapid deceleration requires an external braking option when the application calls for it. Functional scope is identified as Combination C1 + F1. An integrated mains filter reduces conducted switching noise at the power input. The unit is design generation 1, so it follows the first-generation layout for compatible components and parameter structure.
