The R911200578 (RD51.1-4B-037-L-NN-FW) is a three-phase drive controller from Rexroth Indramat for precise control of induction and synchronous motors in industrial production settings. It features a modular design and supports configuration via an integrated control panel with display and keyboard. The unit supports a rated motor power of 37 kW and requires a nominal input of 68 A at 3 x AC 380–480 V (±10%). Key features include a built-in brake chopper, forced air cooling with heat sink and internal blower, and technological functions such as timers, comparators, and ramp function generators. The unit operates on U/f curve control and requires external suppression filters and line reactors to address radio interference and harmonics.
