A06B-6240-H206
Fanuc A06B-6240-H206 aiSV servo module. Known as a servo amplifier module or aiSV this drive is dual axis aiSV 20/40 or aiSV 20/40-B dependent on its build date and which control system it runs with. The earlier 20/40i amplifier manufactured from 2011; and the aiSV 20/40-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 differing ratings; namely aiS12/4000 on L and ai22/4000 AC servo motors on M channel. Controlled from 0i or 3x-A controllers or later -B or plus verison. Servo contains A20B-2101-0621 and A20B-2101-0891 with output across L of 6.5amp and M channel of 13amp.
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.
