RD52.1-4B-055-L-F1-FW

RD52.1-4B-055-L-F1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers series presents a high-performance AC drive converter engineered for demanding industrial applications. This converter delivers a Rated Power of 55 kW from a nominal supply of 3 x AC 380-480 V and features a built-in brake chopper for dynamic braking demands. A rugged forced air cooling system dissipates up to 110 kW of heat, maintaining stable operation under heavy load. With a compact footprint and robust construction, this unit ensures long service intervals and efficient integration into control panels.

In-depth specifications include a Nominal Current of 75 A with dual-range Output Current of 68 A/136 A, supporting input frequencies of 50/60 Hz and an adjustable Output Frequency from 0 Hz to 200 Hz (peak up to 1400 Hz). The drive’s rapid Torque Rise Time of 0.3 msec and Current Cycle Time of 0.1 msec enable precise torque control and fast dynamic response. It withstands electrical noise to EN 50082-2 standards and offers Overload Capability of 200 % for 0.5 s and 170 % for 1 s to absorb transient peaks. Integrated timers, comparators, and ramp-function generators provide versatile sequencing without auxiliary hardware.

Designed for seamless system integration, the RD52.1-4B-055-L-F1-FW communicates via Interbus S and CAN bus, while its four-line graphical Display simplifies local parameter tuning and diagnostics. Enhanced protection features—including earth fault detection, short-circuit protection, and idle safety—ensure reliable operation in harsh environments. Whether retrofitting existing installations or powering new machinery, this Bosch Rexroth Indramat drive controller delivers high availability, precise motor control, and straightforward commissioning for conveyors, extruders, and other continuous-duty equipment.
