The A20B21010390 is a printed circuit board, or a power supply board, for the Alpha I series spindle amplifier. This power supply board module is manufactured by Fanuc. The Alpha I series consists of several modules working together to bring power and control to your system. The ai series consists of servo motors, spindle motors, and servo amps. These modules administer high-speed control with great efficiency. The spindle and servo units are able to achieve this with sharp precision. The control and precision benefit you in a couple of areas. One benefit is the monetary savings, which is a result of the second benefit, which is energy savings. Keeping energy costs down not only saves money but is good for the environment.
