Product Description:
The RD52.1-4B-132-F-W1-FW is a drive controller produced by Bosch Rexroth Indramat as part of the RD 500 Drive Controllers series. The unit regulates three-phase induction or synchronous motors by modulating the applied voltage and frequency in response to process commands. As a controller, it links field sensors and PLC commands to motor torque, allowing closed-loop motion on production lines, test benches, and material handling systems. Because motor behavior is adjusted electronically, the controller can respond quickly to changing commands from upstream automation equipment.
Operating power is matched to large drives through a continuous rating of 132 kW, giving the converter the capacity to run high-inertia loads on continuous duty cycles without derating. It accepts line supplies from 380 to 480 V, and a tolerance of ±10 % allows normal utility variation without interrupting operation. Torque and speed are generated with field-oriented vector control, so the internal processor separates stator current components for accurate flux alignment and responsive motor control. This control method is useful in applications that need smooth acceleration, consistent torque delivery, and repeatable speed behavior. An internal RFI suppression stage limits conducted interference returning to the supply and helps keep nearby equipment operation stable.
Dynamic braking energy is dissipated by a built-in brake chopper, which removes the need for a separate external brake controller during rapid deceleration cycles. Thermal stability relies on forced-air cooling with integrated liquid circulation; fans move enclosure air while an internal coolant path carries heat away from the switching elements. That cooling arrangement supports repeated starts and stops in applications that cycle frequently during normal production. Connection to the plant network is through a three-phase AC converter input, and power leads terminate on 95 mm² terminals C and F for higher-power frame sizes. An integrated mains filter further reduces line noise before it reaches the supply network.
