Product Description:
The RD51.1-4N-007-L-NN-NN-NN-FW is a drive controller released by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. This unit converts fixed mains power into a variable output for asynchronous motors, enabling variable-speed control in conveyor lines, mixers, and general machine tools. It is intended for industrial systems that need adjustable motor speed, smooth startup behavior, and steady operation from a standard plant power source.
The controller handles a rated motor load of 7.5 kW, so it can operate motors in that power class for general industrial duty. It connects to plant power through a three-phase feed and accepts line voltages from 380 to 480 V, which matches common industrial supply levels. The internal rectifier and inverter are arranged for a three-phase AC converter supply, and the control section tolerates line fluctuations of ±10 % without tripping. Motor flux is regulated by U/f curve control, which keeps stator voltage proportional to frequency for stable torque across the speed range. That makes it suitable for pumps, fans, conveyors, and similar loads that do not require advanced servo-style tuning.
Heat produced by the power stage is removed with forced air cooling, allowing installation in ventilated enclosures where airflow can be maintained around the unit. Conducted emissions toward the mains are reduced by an integrated filter, which can simplify panel layout when additional suppression hardware is not required. For rapid deceleration, the drive is supplied without a built-in brake chopper, so regenerative energy must be handled by external hardware when the application returns power to the DC bus. This hardware belongs to design generation 1, indicating the first release of this configuration. The functions menu is not equipped, so optional technology features remain inactive unless compatible plug-in options are installed. Adequate cabinet ventilation remains important because the cooling air path must stay unobstructed during continuous operation.
