Product Description:
The RD51.1-4N-003-P-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It governs three-phase induction motors in automated machinery by converting fixed-frequency mains power into a variable output that sets motor speed and torque. This product is intended for cabinet installation where space, thermal routing, and straightforward parameter setting are priorities in conveyor lines, pumps, and material-handling stations.
The controller is rated for a continuous mechanical output of 3.0 kW and operates from a mains window of 380 to 480 V. A Converter 3 x AC input structure allows direct connection to industrial power systems without an intermediate transformer. Motor excitation is handled with U/f curve control, a scalar method that maintains the voltage-to-frequency ratio so the motor develops predictable torque across the speed range. Power quality on the supply side is improved by an integrated mains filter that attenuates conducted emissions and reduces the need for external line filters. Thermal energy from the power semiconductors is routed into a panel-mounted sink, and the heat dissipation panel arrangement keeps internal temperatures within the permitted range.
No energy-dump circuitry is included, so braking energy cannot be absorbed internally, and the controller is supplied without a built-in brake chopper. Input fluctuations are accepted within a ±10 % tolerance, allowing operation on networks with modest voltage variation. Application-specific functions depend on the firmware, and the controller ships with firmware ordered separately. The hardware belongs to design generation 1 and carries no optional technology functions, leaving expansion to future firmware or peripheral modules as needed.
