A06B-6112-H022#H550 is part of Fanuc Alpha-i Series family with advanced features including
・High mechanical precision and low vibration making it possible to directly connect to the spindle achieving high mechanical precision and low
vibration (V3).
・Utilizes Power source regeneration technology to return regeneration energy of the motor to a power source. Compared with the resistor regeneration, power consumption is greatly reduced.
・Compact, reduced Wiring utilizing fiber optics communications and easy maintenance features such as ability to replace cooling fans without disassembling the unit.
・Center-through-coolant is available by direct connection with the spindle of a machining center. Air cooled αiIT series and oil cooled αiIL series are available.
