Product Description:
The RD52.2-4B-015-L-A1-FW is a modular AC drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. The unit serves as the power and regulation element between mains supplies and motor windings, providing speed and torque control in conveyor lines, packaging equipment, and general factory automation. By combining a power converter, control electronics, and protective circuitry in one housing, it streamlines panel layout while maintaining the deterministic response required in multi-axis industrial installations. This arrangement also suits cabinet-mounted systems that need controlled acceleration, stable running speed, and responsive deceleration.
It delivers a continuous output of 15.0 kW, and its three-phase input window spans 380 to 480 V, enabling direct connection to common plant distribution networks without an autotransformer. The power section is configured as a Converter 3 x AC, which integrates rectification and inversion for four-quadrant operation. Motor performance is handled through field oriented vector control, which calculates real-time flux and torque components to maintain precise speed regulation under varying load. Dynamic braking energy is redirected by the built-in brake chopper, permitting rapid deceleration without overstressing the DC bus. The drive uses a second-generation platform that supports the control structure used in this model.
Thermal management relies on forced air cooling, so cabinet airflow must be directed across the heat sink fins to maintain rated current. Line-side interference is attenuated by an integrated mains filter, which helps reduce conducted noise on the supply connection. Component tolerances on current, voltage, and control loops are qualified to a ±10 % tolerance, giving clear operating margin for surrounding equipment. Safety and energy options include an external standby power arrangement for low-load idling and a starting lock-out that prevents unintended motor motion when the axis should remain disabled.
