Product Description:

The RD52.1-5B-132-R-VW-FW is a drive controller produced by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. As a high-power industrial module, it works with power conversion equipment to regulate induction or synchronous motors in production cells and process lines. This allows the unit to provide controlled torque, stable speed regulation, and positioning response for automated machinery. It is suited to installations where the drive must handle long operating cycles, frequent speed changes, and controlled deceleration under heavy load.

The controller is rated for 132 kW, supporting applications with substantial continuous motor demand. Regulation is based on field-oriented vector control, which separates torque and magnetic flux components so the drive can react quickly to changing load conditions. The power section is arranged for a three-phase AC converter input and a mains level centered on 500 V. Heat is removed by liquid cooling with an internal pump, allowing the cooling circuit to transfer losses to an external heat exchanger instead of depending on cabinet airflow alone. Regenerated energy during braking is handled by a built-in brake chopper, which helps keep the DC bus within its allowable range when the motor decelerates rapidly.

The unit belongs to Generation 1, so it follows the first hardware release of the series. Its available control package is identified as V1 + W1, which combines standard speed control with added process-related functions for broader application use. The required software is ordered as a separate subposition, allowing the drive behavior to be matched to the intended motion profile without changing the main power hardware. This arrangement keeps the hardware platform consistent while allowing the operating functions to be selected for the machine task.
