Product Description:
The RD51.1-4N-007-L-C1-FW is a drive controller produced by Bosch Rexroth Indramat and supplied within the RD 500 Drive Controllers series. As a converter-based unit, it interfaces a three-phase mains supply with induction motors used in conveyors, mixers, and similar industrial axes. By regulating stator frequency and voltage, it allows speed adjustment and torque matching for automated processes that require consistent motion control. This type of drive is commonly used where process speed must change smoothly instead of staying tied to a fixed mains frequency.
This controller delivers a nominal output of 7.5 kW, which is the rated motor power it can supply under normal operating conditions. It accepts line voltages from 380 to 480 V and tolerates input fluctuations of ±10 %, so it can remain in service on industrial grids that vary within that range. Motor excitation follows U/f curve control, where output voltage rises with frequency to help maintain magnetic flux and stable torque through low- and mid-speed operation. That control method is well suited for general-purpose variable-speed duties that do not require more complex feedback-based motor regulation. The design is supplied without a built-in brake chopper, so rapid deceleration requires external braking hardware or another means of handling returned energy.
Thermal management relies on forced air cooling, allowing the power electronics to release heat into the airflow rather than into the mounting panel alone. Because the cooling air carries heat away from the enclosure interior, the installation needs a clear path for intake and exhaust flow. Line-side interference is reduced by an integrated mains filter, which helps limit conducted noise on the incoming supply and reduces disturbance to nearby equipment on the same power system. Control circuitry remains active during mains outages through 24 V stand-by power, so logic functions and communication can remain available during short interruptions. The power section uses a three-phase AC converter arrangement, making the unit suitable for standard industrial supply systems and separating incoming power conversion from the motor output stage inside the controller.
