Fanuc A06B-6064-H327 Spindle Amplifier Drive. This model 30S/50P AC spindle drive is the largest in the yellow plastic frame and case utilising serial interface via fibre optic communicating with the CNC. This series of drive was originally introduced with the 32bit 0-MC/0-TC control systems with serial output (F/O) on the memory card. As this drive is the 3rd generation serial series its software A06B-6064-H327#H550 allows it to replace earlier version serial amplifiers assuming matched ratings. Contact us for more information if you find you need to do this.
Not being the largest drives in the 6064 series the H327 is still powerful driving large model 30S or 50P spindle motors. For bigger motors, Fanuc produced older style anaodized serial spindles up to model 60S rating. This drive is made up of several layers allowing for excellent thermal radiation. At the back is the power components such as capacitors, contactors, transistors on a large heatsink as well other high powered devices. Next is the wiring PCB A20B-1004-0742 (not available seperatetly) which directs the power to the blue connectors. As a result these send voltages onto the firing circuit pcb (A20B-2000-0220) with bridge rectifiers, smaller transistors and opto’s, etc. Working in combination with A16B-2201-0440 spindle control pcb (or the logic and communications board). Together these make up the A06B-6064-H327 AC spindle servo unit.
At DNC we have supported these serial spindle drives since our inception. As a Fanuc specialist repair facility we have repaired hundreds of 6064 series drives over the years and supplied this model to many well known manufacturers in the Automotive and Aerospace industries. Currently we have this drive in stock; when we don’t we can rely on group stocks to back us up.
