They expect the person fitting the unit to be competent or experienced enough to factor in that certain amount of Back Emf will be produced. It's common knowledge even at DIY level that safety factor is required which is often advised being around 10% less than Max rated voltage.

It's dangerous and foolish to assume that any manufacturer as built in "safety" factor and then Ignore the Warning Given in the Same Manufacturers Manual.!!

It's even MORE FOOLISH to thentry an Rubbish what someone with years of experience is telling you will happen if you run at those Voltages.

Now I should tell you to get stuffed you arrogant "Aussie Bastard" but in the spirit of helping people then I'll just say. Gecko after sales service is legendary so Contact Gecko tell them you your issue and they Will replace/repair the unit for you.

Oh and the Voltage Calculation is just that.? A Calculation based on the Motors parameters and should be used has guide line for Motor Voltage and doesn't mean just because your motor specs calculates that 50V is ideal voltage you can run at this voltage on the drives.!!
