Product Description:
The RD52.2-4B-015-P-A1-FW is a drive controller from Bosch Rexroth Indramat in the RD 500 Drive Controllers series. Installed between the mains and an asynchronous or synchronous motor, it converts fixed-frequency line power into a regulated output that matches moment-to-moment process requirements. In automated handling, pumping, or forming equipment, the unit receives setpoints from a higher-level PLC and adjusts torque and speed with millisecond response. This makes it suitable for variable-speed duties where motor output must follow changing load demand.
Electrical sizing is centered on a rated output of 15.0 kW, allowing the device to run moderate-horsepower machines without derating. The input network accepts line potentials within 380 to 480 V, and its front end is configured as a three-phase AC converter, so three-phase utility feeds can be wired directly to the terminals. Thermal control is handled by a rear heat dissipation panel; this passive cooler supports frame ratings up to 18.5 kW and allows the unit to be mounted inside a sealed cabinet. A built-in brake chopper protects the DC link by diverting regenerated energy to an external resistor during rapid deceleration, so voltage stays within a safe range.
Motor performance is regulated with field-oriented vector control, providing dynamic current modulation and precise flux alignment over the full speed range. This control method also helps the drive maintain stable torque at low speed during changing load conditions. Line-borne interference is reduced by an integrated mains filter, eliminating the need for additional RFI components in most installations. This model belongs to design generation 2, and input fluctuations are tolerated within ±10% of nominal, helping the controller stay operational on weak grids. Standby power can be supplied from an external source, and the unit includes a starting lockout.
