FANUC A20B-2101-0390

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. These products are manufactured in Japan and are designed for Commodity production, advanced machining, and CNC milling usage. They come with a 2-year warranty from MRO Electric. We also carry Power Supplies from other manufacturers such as Siemens and Control Techniques.

Features

The basic units that comprise the Fanuc ai series or Alpha I series, are the power supply (PS), the servo amp (SV), the spindle amp (SP), the AC reactor, connectors, fuses, and a power transformer.

The connectors directly beneath the LED are the CX1A input connection and the CX1B output connection. Beneath the input and output connections is the CXA2A connection. The bottom half of the Fanuc A20B21010390 has the JX1B, CX37, CX3 MCC, and CX4 ESP connections.

How to use the A20B21010390

The Fanuc A20B21010390 works within the whole ai series and is for use with the Fanuc servo amp. This is a basic overview of connecting the system. The CNC, servo motors, servo amps, and other modules in the Fanuc ai series must have specifications checked to ensure the units are the correct ones for your stipulations and the wiring is correct. If the connections are properly connected, power on is the next step and set the initial parameters on the CNC. After measuring the AC power voltage, connect the power. Next check that the protective ground line is correctly connected and select the ground fault interrupter that complements the leakage current. After you check the Phase sequence of the fan motor supply to ensure the motor rotates in the desired direction to avoid a decrease in cooling efficiency. Now you are ready to initialize the parameters.
