The R911200578 (RD51.1-4B-037-L-NN-FW) is a three-phase industrial drive controller, conceived by Rexroth Indramat, designed to meticulously regulate induction and synchronous motors in production and processing environments. Sporting a flexible modular design, the controller can be tailored to fit specific drive applications. Notably, it generates radio interference and harmonics fed back into the line supply; this requires use of additional components such as radio interference suppression filters and line reactors for optimal performance. The controller incorporates numerous technological functions like timers, comparators, and ramp function generators. Its integrated control panel featuring a display unit and keyboard simplifies operation and monitoring. For optimal output, a rated input of 68 amperes is needed which can drive motor power up to 37 kilowatts. The controller also employs a heat sink and an internal air blower for temperature management via forced ventilation. It is available for global shipping with a one year warranty from Indramat USA.
