The FANUC A06B-6110-H026 and A06B-6140-H026 power supply modules share identical electrical and performance specifications within the FANUC αi Series. The only difference lies in their internal control board design. The A06B-6110-H026 is equipped with control board A20B-2100-0761, while the A06B-6140-H026 uses control board A20B-2100-0391. Both models provide the same power capacity, input/output voltage range, and compatibility with FANUC αi servo and spindle amplifiers. When replacing or repairing these units, it is important to match the control board version to ensure proper communication with the connected drive and CNC controller.
Below are some common faults that may occur in FANUC αi series power supply modules such as A06B-6110-H026 (αiPS26).
All of these issues can be diagnosed and repaired by CNCFixtech technicians.
