The R911240714 (RAC 2.2-250-380-L00-W1) AC Main-Spindle Drive Controller, produced by Indramat, is designed for a current of 250A with a voltage connection rated at 3*AC 400V 50-60 Hz. It includes a unified mains contactor and emergency stop switch. The controller has an incorporated position control loop, enabling precise spindle positioning with a maximum resolution of 1/400000 revolutions. With high stiffness, a wide speed range, and constant power, it's especially ideal for serving as a primary spindle drive in numerically controlled machinery. Featuring internally built heat sinks, the controller allows easy structural modifications for air cooling, while also offering an option for hose cooling, with the necessary parts supplied. The controller is compatible with three different interface formats (Analog speed set-point, digital speed set-point, and SERCOS interface) and operates optimally between 5-45 degrees Celsius and under 1000m altitude above sea level, with a humidity below 70%. The unit is IP10 certified and can be fixed on-site if damaged. A warranty of one year is offered by Indramat USA.
