Fanuc Velocity Control Unit A06B-6050-H104 m00612

Used in Fanuc CNC systems requiring analog AC servo axis control, the Fanuc A06B-6050-H104 is a single channel AC velocity control unit designed to drive Fanuc AC servo motors in the Model 20S and 30 class. The unit carries type number A06B-6050-H104 and manufacturing number P71000188 as shown on the nameplate label. Manufactured by Fanuc Ltd in Japan, this drive belongs to the early generation of Fanuc AC servo amplifiers built around an open wired anodized power section paired with a dedicated control board, visible in the photos as PCB A76L-0300-0077. The assembly includes an integrated transformer section, power transistor array, and terminal block wiring interface with positions labeled A through 8. A secondary terminal block labeled T2 with positions 4 through 6 is visible on the upper section of the chassis. The control board carries a 16.000 MHz crystal oscillator (CXO-104B) and an Omron G2U-114P 24VDC relay. The chassis label also references internal configuration AC-H104.304. This unit is commonly sought as a replacement or spare for Fanuc 6 and Fanuc 10 series CNC machining centers and turning centers that use analog velocity feedback servo systems.
