Product Description:
The RD51.1-5B-015-L-D1-FW is a drive controller produced by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It varies output voltage and frequency for standard AC motors so speed and torque can be matched to conveyors, pumps, and similar plant equipment. Its modular format supports cabinet installation alongside PLCs and contactors, and it provides the power conversion stage between the incoming supply and the motor load. This arrangement suits centralized control panels where adjustable motor operation is required without using a direct-on-line starter.
At a rated output of 15.0 kW, the controller can feed medium-sized induction motors without added derating. The incoming supply uses a three-phase AC converter topology, so the device rectifies three-phase mains before synthesizing a new AC waveform within the permitted 500 V line window. Speed regulation uses U/f curve control, which reduces stator voltage in proportion to frequency so magnetic flux remains usable as motor speed falls. This method is suitable for general-purpose variable-speed duty where stable motor operation is more important than highly dynamic servo response. A built-in brake chopper routes regenerated energy into an external resistor during rapid deceleration, helping prevent DC-bus overvoltage trips on loads with significant stopping energy.
Thermal management relies on forced-air cooling, with a blower moving cabinet air across the heat sink to keep the power semiconductors within operating temperature limits. Control wiring terminates on a NAMUR terminal strip, which supports interlock and status circuits arranged to NAMUR signaling practice. The electronics can remain active from external 24 V standby power when the main supply is isolated, allowing control logic and stored settings to remain available during service states. The application software is ordered separately, and the hardware is built to design generation 1. This separation allows the controller to be matched to the intended control task without changing the base hardware platform.
