Product Description:
The RD52.1-4N-003-L-V1-FW is a drive controller produced by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. It provides closed-loop regulation for induction or synchronous motors in automated machinery, helping the drive system match motor behavior to changing process demands. By processing current, voltage, and position feedback, the unit supports stable speed and torque control so that axes can follow motion profiles issued by a PLC in packaging, material-handling, or machining equipment. This operating role makes it suitable for applications where coordinated motion and repeatable response are required across varying load conditions.
The controller accepts a three-phase mains input of 380 to 480 V and is rated for 3.0 kW of continuous output. It uses field-oriented vector control, which allows separate control of flux and torque for responsive motor behavior, especially at low speed. The supply topology uses a 3 × AC converter, so the unit is intended for connection to a three-phase AC source. Incoming voltage tolerance of ±10 % helps the controller remain operational during moderate variations in the supply network. These electrical characteristics support steady motor performance without requiring unusual supply arrangements for standard industrial installations.
Thermal management relies on forced air cooling, so the installation area must allow clear airflow around the heat sink and ventilation path. The housing is supplied without a built-in brake chopper, which means an external braking solution is needed when the application involves frequent or rapid deceleration. An integrated mains filter reduces conducted emissions and can simplify cabinet layout by limiting the need for additional filtering hardware. For standby functions, the unit uses 24 V standby power from an external source, allowing control electronics to remain energized while the main power section is switched off. This arrangement can support diagnostic access and controlled system behavior during shutdown or service conditions.
