Fanuc A06B-6240-H207 aiSV servo module. Known as a servo amplifier module or aiSV this drive is dual axis aiSV 40/40 or aiSV 40/40-B dependent on its build date and which control system it runs with. The earlier aiSV 40*2 manufactured from 2011; and the aiSV 40/40-B built from late 2015 with an earlier varient running on various controls and later version running on 3x-B models or equiv 0i plus control.
Note: Labelled as a servo module; it is indeed a servo amplifier module!
Part of the ALPHA i generation of 200VAC amplifiers from the 62xx series. Also power supply 620x and spindle amplifiers 622x drives. This servo amp powers two motors of the same ratings; namely aiF8/4000 or a12/3000iS series AC servo motors. Controlled from 0i or 3x-A controllers or later -B or plus verison. Servo contains A20B-2101-0622 and A20B-2101-0891 with output across all channels of 13amps.
Please note -B varients are generally not interchangeable for earlier non -B versions of the servo drive due to software compatibility on amp and CNC control.
