PVE trouble

<< < (3/3)

Jelmer:
Thanks you guys, this problem is long being solved (=worked around). funny that no one from Sauer Danfoss came up with this when I had the problem. It's good to  know for the future.

Marbek_Elektronik:
Is there only 1 Resister in the cable or 2?
Because the signal have to be in the middle of the power supply, for example 6V by 12V system.
If you have 1Ohm in series you there is a loss of voltage of o,7V (1R , 0,7A)
So there is 11,3V. But the signal is 6V. So it is 53% of voltage.

If there is another Resistor in negative supply voltage, you get
0,7V and 11,3V at the valve and the 6V signal is in the middle.

If you have 24V, my idea is to switch all 6 valves with 1 Output and a resistor!
After a short time, you switch a second port in parallel with no resistor to drive all 6 valves.
This only works by 24V because of the smaller current.
