Product Description:
The RD52.2-4B-007-L-A2-FW/S133 drive controller is produced by Bosch Rexroth Indramat as part of the RD 500 Drive Controllers series. Designed for cabinet installation, the unit receives line power, modulates it through an IGBT bridge, and delivers controlled output to AC motors used in conveyors, mixers, and positioning modules. Through integrated current and voltage feedback, it lets the higher-level control system manage acceleration, deceleration, and steady-state speed without mechanical contactors. This arrangement supports repeatable motor behavior during load changes and frequent start-stop cycles in automated production machinery.
The controller operates from a three-phase AC converter supply and accepts mains from 380 to 480 V, which suits common industrial power systems. Within that range, the input can vary by ±10 % without interrupting normal drive operation under typical conditions. Internal processing uses field-oriented vector control, which separates torque-producing and flux-producing current components for responsive speed regulation and stable low-speed performance. At the motor terminals, the device can deliver up to 7.5 kW of continuous mechanical power, making it suitable for medium-duty pumps, fans, conveyors, and similar equipment that require controlled acceleration and consistent running speed.
A built-in brake chopper dissipates regenerated energy during rapid deceleration and helps protect the DC link from overvoltage. Thermal management relies on forced air cooling, so the cabinet layout should leave clear intake and exhaust paths through the heat-sink channel. An integrated mains filter reduces input harmonics and helps limit electrical noise on the supply connection, which supports cleaner operation around nearby control equipment. The drive also supports external standby power, and its starting lock-out function helps prevent unintended motor energization after a fault or power recovery.
