Product Description:
The RD52.1-4B-015-P-V1-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the RD 500 Drive Controllers series. It regulates motor current and output frequency so industrial equipment can maintain commanded speed and torque under changing load conditions. The unit is part of design generation 1 within this product line. Because it adjusts both frequency and current, it can support smooth acceleration, deceleration, and speed holding in systems with changing process demand. This makes it suitable for variable-speed drive tasks in process machinery, material handling systems, and other factory installations.
This controller delivers a rated output of 15.0 kW to the connected motor. It operates from a three-phase line supply in the 380 to 480 V range, and the power section uses three-phase AC converter operation so it can rectify and modulate industrial power directly. The allowed line variation is ±10 %, which helps the drive continue operating properly when incoming voltage shifts within the permitted band. This electrical arrangement fits common industrial distribution systems used in production equipment and packaged machines. Heat from the IGBT section is transferred through a heat dissipation panel, so cabinet cooling can be managed through the mounting surface instead of relying on a dedicated blower inside the unit.
During deceleration, excess energy is handled by a built-in brake chopper, which reduces the need for separate braking components during short stopping cycles. The control system uses field-oriented vector control to support fast torque response and accurate low-speed operation when the load changes quickly. Conducted electrical noise is reduced by an integrated line filter, helping limit interference on the incoming supply lines and keeping the installation layout simpler. An auxiliary input for 24 V standby power keeps the control electronics active when the main power section is disconnected, which helps preserve communication readiness and stored parameter data. This is useful when the control section must remain available during brief line interruptions or when the power stage is switched off.
