The Indramat R911261926 (RAC 2.3-200-460-D0I-W1) spindle drive controller is a high-performance, intelligent digital control unit designed for numerically controlled industrial machinery. Tailored specifically to work with main servo motors like Indramat 2AD asynchronous main spindle and 1MB frameless spindle models, it supports an extensive speed range, delivers robust power persistently, and boosts machine productivity. Uniquely, it can discern rotor positions with ultra-high precision up to 1/4 000 000 revolutions, enabling full motor control even on the slowest speed. This 121 kg controller is rated at 300 amps current, offering a steady input of 55 kW, while during power interruptions, continuous regeneration power sits at 37 kW but can peak at 55 kW for 5 seconds. Connections facilitate feedback, CNC, and controller specifics. The device, devoid of a bleeder, additional interface or encoder input, is integrated with an air fan and heat sink, and should not be used in temperatures exceeding +55 degrees Celsius. It is safety tested, IP54 rated, can be shipped worldwide and is accompanied by a year-long warranty from Indramat USA.
