Product Description:

The RD52.2-2B-015-L-A1-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. Installed between the plant's AC mains and the motor, it modulates output voltage and frequency so the connected machine receives the electrical profile needed for repeatable motion. In industrial automation lines, this allows the drive to adapt motor operation as process demands change during normal use. It is suitable for conveyors, pumps, and positioning axes that require stable speed control and predictable process behavior.

This controller uses field-oriented vector control to separate torque-producing and magnetizing current components, giving the drive a fast response to load changes without requiring mechanical feedback devices. Input power is supplied through a three-phase AC converter input with a nominal range of 200 to 230 V. The power stage is rated at 15.0 kW, so it can drive motors at that continuous output level. Regenerative energy during braking is handled by a built-in brake chopper, which reduces the need for an external braking resistor in many applications. Thermal management is provided by forced-air cooling, and directed airflow over the heat sink helps keep internal power components within allowable operating temperature limits during continuous duty and short overload events.

The control section includes external stand-by power with starting lockout, so low-level control voltage can be supplied from an independent source while unintended restarting after power restoration is prevented. That arrangement allows supervisory control functions to remain active even when the main power path is disabled. This model is from design generation 2, which indicates an updated control and mechanical platform within the RD52 range. The controller supports stable operation in automated systems where drive response, braking control, and compatibility with standard three-phase supplies are important.
