Product Description:
The Bosch Rexroth Indramat RD52.2-2B-018-L-A1-FW belongs to the RD 500 Drive Controllers series and is supplied for general-purpose automation tasks that require closed-loop speed and torque regulation. The device conditions incoming power, processes motor feedback, and delivers regulated output pulses to maintain commanded operating points. It is used in conveyor lines, packaging stations, and process machinery where repeatable motor performance and coordinated motion support stable throughput and product quality. Its closed-loop design also helps the drive correct speed deviations as load conditions change during continuous operation.
Control is executed through field-oriented vector control, a method that transforms stator currents into d-q components so that torque and flux can be regulated independently with high dynamic response. This approach separates torque-producing and magnetizing current components, which helps the motor respond smoothly during acceleration and load changes. The power section accepts a three-phase AC supply and is rated for a line window of 200 to 230 V, matching low-voltage distribution systems common in light industrial plants. At its continuous rating of 18.5 kW, the controller can drive mid-frame induction motors used in pumps, extruders, or smaller presses. Thermal energy generated by the IGBTs is removed by forced-air cooling, supporting dense cabinet layouts without immediate thermal buildup.
A built-in brake chopper is integrated on the DC link to divert regenerative energy into a resistor and prevent overvoltage during rapid deceleration or vertical load lowering. Safety and service functions include external standby power with starting lockout, which allows the control electronics to remain active while motor starting is inhibited. The unit is from design generation 2, with hardware dimensions and connector pinouts matched to other RD controllers in the same generation. This layout keeps the mechanical and electrical interfaces consistent within that product generation.
