Product Description:
The industrial motion product RD52.1-4N-110-L-V1-FW is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the RD 500 Drive Controllers series. Within an automation cell, this unit interfaces with a three-phase mains supply and a motor inverter stage, delivering closed-loop regulation of speed and torque for large AC machines. By coordinating current, voltage, and frequency, it enables precise process control for conveyors, extruders, and similar high-demand loads in continuous-duty production.
This controller is specified for a nominal output of 110 kW, giving it the capacity to operate sizable induction or synchronous motors without derating at rated line conditions. Vector modulation is accomplished through field-oriented vector control, which adjusts stator currents to align with rotor flux and maintain dynamic torque response. The power section accepts line voltages from 380 to 480 V, and the front end is engineered as a three-phase AC converter so installation is tied directly to a three-phase mains transformer or busbar. Heat generated by the IGBT stack is removed through forced air cooling, allowing cabinet temperatures to stay within component limits during continuous full-load operation. Generation 1 design conventions govern the mechanical layout, and the unit accommodates the stated input tolerance during normal operation.
The power stage is supplied without a built-in brake chopper, so dynamic braking requires an external resistor module when rapid deceleration is needed. Line-side interference is minimized by an integrated mains filter, which reduces conducted emissions into the facility network. Control electronics remain energized during main power isolation through 24 V standby power, furnished from an external supply for parameter retention and fieldbus communication. Component ratings tolerate supply deviations of ±10 %, permitting operation on utility feeds with moderate voltage variation.
