Product Description:
The RD51.1-4B-015-L-C1-FW belongs to the RD 500 Drive Controllers series produced by Bosch Rexroth Indramat. Within an automation cell, this unit conditions three-phase mains power so that induction motors receive variable voltage and frequency matched to load requirements, allowing coordinated speed or torque control across conveyors, pumps, or process lines. This operating method lets the drive respond to changing process demand without relying on a separate motor starter for routine speed adjustment. The unit uses three-phase AC input, so the rectifier and inverter stages are combined inside the housing to simplify cabinet layouts.
This model delivers a continuous output of 15.0 kW, giving mid-range machinery adequate mechanical power without oversizing the electrical section. That output level suits medium-duty equipment that must run continuously through standard production cycles. It accepts line supplies between 380 to 480 V and permits a tolerance of ±10%, so it remains stable on networks that experience moderate voltage swings. This range covers common industrial distribution systems without requiring unusually tight incoming power conditions. Regenerative energy produced during deceleration is dissipated by a built-in brake chopper, protecting the DC link and external components. A firmware cartridge must be ordered separately to match the required application profile.
Motor regulation is based on a programmable U/f curve control profile, which is adequate for pumps or fans that do not need vector feedback. Thermal stability is maintained through forced air cooling; users must provide unobstructed airflow paths when mounting the drive in an enclosure. Mains distortion is reduced by an integrated mains filter, and 24 V standby power terminals support logic retention without a separate auxiliary supply on cabinet sizes up to 110 kW.
