Formula for Current Draw or Full Load Amps

Full Load Amps (FLA) is included on the robot controller labels, but it is for 380VAC, which provides the maximum possible FLA for the controller.

FYI, here is the formula for calculating FLA for robot:

Here is an example for the GP50:

For Single Phase, you do not multiply the input voltage by the square root of 3 in the denominator.

The square root of 3 is 1.73205080757
