Non-backdriveable means that torque applied to the output shaft will encounter sufficient friction that it will not turn the motor (with no voltage applied to the motor). It does NOT mean that the system cannot be driven in reverse from the motors.
I'm pretty sure I know what backdriveable means. According to a thread for one of the other pictures, the gearboxes are [url=https://catalog.nordex.com/pc2743_26612]these[\url] worm gearboxes. They appear to be from the same line as the worm gearboxes we used last year, where torque on the output shaft is not transferred to the input shaft. Therefore the ones we used last year were non-backdriveable. I was cautioning that if they are the same as the ones we used, then they probably are not a good option as a drivetrain gearbox.
