Product Description:
The RD52.1-7N-004-L-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It is intended for cabinet-mounted inverter systems where precise speed and torque regulation of AC motors is required in automated production cells, packaging lines, and material-handling equipment. By translating reference commands from a PLC into controlled three-phase output, the unit maintains stable motor behavior during acceleration, constant running, and deceleration phases. This allows the drive to support repeatable motion on conveyors, process sections, and other axes that must hold steady speed under changing load.
This controller operates from an inverter DC bus and accepts a DC link voltage between 530 to 670 V, allowing it to share energy with other modules on the same supply rail. Motor regulation is executed with field-oriented vector control, so current is separated into torque-producing and flux-producing components for accurate dynamic response. Thermal management is handled by forced-air cooling; a rear-mounted fan drives airflow across heat sinks to keep semiconductor junctions within safe limits. Because the unit is supplied without a built-in brake chopper, external dynamic-braking hardware must be added when rapid regenerative stopping is needed. The unit is part of Design generation 1, indicating compatibility with first-generation RD 500 option cards and cabling.
The controller uses standard terminal assignments and has no optional function packages installed, leaving room for user-defined I/O extensions without changing the base hardware layout. It matches frame sizes that use the same forced-air ducting, so exhaust routing can be shared across a drive rack and cabinet airflow can remain organized. Application-specific parameters require firmware ordered as a separate subposition, so the memory module can be selected for the target motor data and fieldbus protocol during project planning. This arrangement keeps the hardware adaptable for different motor and interface combinations while preserving the same controller platform.
