Product Description:
The RD52.2-2B-007-L-A1-FW drive controller is manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It is intended to control variable-speed induction or synchronous motors in automated production cells, providing closed-loop regulation of speed, torque, and direction during conveyor travel, winding tasks, and other coordinated machine motion. By switching insulated-gate bipolar transistors through an internal control board, the unit converts fixed mains power into a commanded output waveform so the motor can accelerate, decelerate, and reverse in a controlled manner. This operating method supports repeatable motion in packaging, material handling, and similar industrial systems where process consistency matters.
The controller uses field-oriented vector control to separate flux and torque, giving the drive fast response at low speed and steadier control under changing load. Thermal management relies on forced air cooling, so heat is removed continuously without liquid circuits or external coolant plumbing. Within its input range of 200 to 230 V, the power section accepts a 3-phase AC supply and electronically reshapes it for the connected motor. At rated conditions, the inverter delivers 7.5 kW of shaft power, which suits medium-duty equipment such as mixers, extruders, and small presses that need adjustable motor speed throughout the operating cycle.
Further hardware includes a built-in brake chopper, which routes regenerative energy to an external resistor so the DC bus stays within safe limits during deceleration or overhauling loads. Safety functions include a starting lockout circuit that helps prevent unintended motor startup when the control state is not ready for operation. A standby power terminal keeps the control electronics energized when the main supply is switched off, allowing control functions to remain available without full motor power. The unit is part of design generation 2, which places it within the second revision of the RD 500 hardware platform.
