1 Run each robot axis to a position where the combined weight of the robot
arm and any load is maximized (maximum static load).
2 Switch the motor to the MOTORS OFF.
3 Inspect and verify that the axis maintains its position.
If the robot does not change position as the motors are switched off, then
the brake function is adequate.
