Technical description and application scope
A290-1406-X401 is an exact FANUC reference from the user-selected CNC product pool. Technical identity and numeric data are limited to values explicitly supported by manufacturer documentation.
For spindle motor terminal/junction box component selection, verify the complete part number together with mechanical/electrical interface and host-machine compatibility. Visual similarity alone is not an interchangeability criterion.
Automation evaluates the part within maintenance, retrofit and troubleshooting applications.
