Product Description:
The RS51.1-4G-003-V-NN-FW is a drive controller produced by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It serves as a basic power stage that links the plant mains to induction motors in automated material-handling lines, conveyors, and auxiliary motion axes. By modulating output frequency and voltage it maintains motor speed within predefined curves, making it suitable for straightforward speed regulation tasks in industrial automation.
This model applies U/f curve control, so the output voltage follows a fixed ratio to frequency for stable torque across the speed range. Its input is rated at 3 kVA, defining the apparent power the converter can deliver to the motor circuit under nominal conditions. The supply interface is a Converter 3 x AC arrangement that connects to three-phase mains inside control cabinets. Operation is permitted within a line window of 380 to 480 V; this span covers the common 400 V and 480 V plant grids. Permissible mains fluctuations are held within ±10 %, a margin that prevents output derating when voltage drifts occur during peak demand or generator operation.
The unit is equipped with a Built-in brake chopper and resistor that dissipate regenerated energy during rapid deceleration, eliminating the need for an external braking module. A factory-installed integrated mains filter attenuates conducted emissions, supporting cabinet compliance with industrial EMC limits. Hardware is identified as Design generation 1, which defines connection layouts and compatible firmware codes. Because firmware is supplied separately, the appropriate program must be ordered as an independent subposition before commissioning. The controller is listed as a Basic Drive; consequently, optional technology functions are not equipped, leaving application-specific logic to higher-level PLCs or motion controllers.
