Product Description:
The RR52.1-7N-030-D-V1-FW drive controller is produced by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It mounts on a common DC bus and drives three-phase induction or synchronous motors in automated production cells. By converting bus energy into variable frequency and voltage, the unit delivers the speed and torque regulation needed for material handling, machining, and other process equipment while remaining compatible with higher-level PLC sequencing. This arrangement allows the controller to support coordinated motor operation without requiring a separate AC input stage inside the unit.
The controller delivers 30 kW and runs from a DC link between 530 to 670 V, allowing operation on different rectified mains. The allowable DC bus ripple within that window accommodates typical three-phase diode front-end tolerances. With an Inverter DC supply, it depends on an upstream converter while all pulse-width modulation is handled internally. Motion regulation uses field-oriented vector control, separating flux and torque for fast response. Heat is carried outside the cabinet by a plug-through cooler sized for drives up to 110 kW. Because it is supplied without a built-in brake chopper, any energy recovered during rapid stops must be dissipated through an external braking resistor or module.
An auxiliary feed supplies 24 V standby power, keeping control electronics active for diagnostics when the main bus is off. The unit is part of design generation 1, matching first-series RD 500 option cards and parameter files. The required control software is ordered separately, so the drive can be matched to the installed system. Diagnostic status signals appear on the local keypad and through available fieldbus links. This supports troubleshooting and status monitoring without changing the controller’s power stage arrangement.
