Product Description:
The RD52.2-5B-015-L-A2-FW is a drive controller produced by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. In an automation cell, it links a three-phase mains source to an induction or synchronous motor and modulates torque and speed so actuators follow programmed motion profiles. By converting fixed-frequency line power into a variable voltage and frequency output, the unit supports controlled acceleration, stable running speed, and repeatable deceleration in conveyor sections, extruders, and coordinated axes. This operating principle lets one controller handle both steady-state process motion and dynamic speed changes during indexed machine cycles.
An integrated built-in brake chopper diverts regenerated energy to a resistor network, preventing DC-link overvoltage during deceleration. Motor flux is computed in real time through field-oriented vector control, so torque remains linear even at low speeds and response stays consistent under changing load. Thermal loads are managed by a forced-air cooling system that channels cabinet air across the heat sink, so unobstructed airflow is required around the unit. The controller delivers up to 15.0 kW of rated mechanical output for mid-range production machinery that runs continuously. Line power is accepted through a 3 x AC converter front end, allowing connection to standard industrial feeders and common DC bus architectures without an external rectifier.
The power stage is designed for a nominal link voltage of 500 V, giving sufficient headroom for high-speed motors while staying within typical insulation classes. The hardware is generation 2, which is used with the corresponding plug-in option cards and diagnostic structure for this unit. Functional additions include external standby power and starting lockout, which support safety circuits that keep the axis inactive until permissive signals are present. As a programmable Drive Controller, it can be adapted to application requirements through control parameter settings and compatible option modules. This arrangement helps the drive fit machines that require interlocked startup behavior and flexible control expansion without changing the basic power section.
