G540 - 4 motor connection problem

[dachopper]

Well that's news to me and I've fitted quite few now.! . . . Think you should read again because in the manual on Gecko web site which I've just been reading to make sure things haven't chenged there are still big warnings about NOT exceeding 50Vdc.!! . . . Which with 48Vdc you will get above with back EMF.

....

You can't possibly expect a consumer, to read a manual that says use less than 50 Volts, then they purchase a power supply that inputs' less than 48 Volts, even 42 volts, and then say, oy you didn't factory in the manufacturers back EMF effect - there is no mention of this anywhere - but there is mention of of the formula to calculate the ideal voltage, and that is close to 50 volts.

I don' think this is the issue - sounds like I have one of the units with the current set resistor at 8 amps, and because of my application, the overcurrent protection circuit is going off.

Shame because I was told in 2016 by automation tech that they were selling me one of the latest models.... and after reading the 2012 post, they knew about this 4 years ago?

If this is what the problem is..... it sounds absolutely identical to the behaviour I am seeing
