Servo Amp Module Alpha-12X2 A06B-6079-H201

The FANUC alpha-12X2 servo amp module is a superbly engineered drive unit. As with all CNC machines, though, there are internal parts which will eventually succumb to the rigors of high-volume production environments. Corrosion, dust and heat all take their toll on capacitors, ICs and power and transistor modules. When the inevitable happens, Tri Star CNC will get your machine back and running quickly.
