First, I got an alarm 310606 on lathe machine (UTIMAC SCN 26HT), I fixed that by slightly increasing the voltage on the power supply (voltage for pins that require 26.5V). 

Now I keep getting an alarm 25080 for X2 & X3 axis that use hydraulics for movement. I checked the voltage for valves on the SIMODRIVE 611 card pins and it all looks ok (there is no red led anywhere all the correct status lights are on on the power module & cards).

I am even unable to do the referencing sequence of the lathe machine because there is no movement on X2 and X3 so the overall time is too slow and again alarm 25080 pops up. The strange thing is that if I manually try to move any of those axis the values change on the computer but the actual axis doesn't move. 

If switch the valve on I can see lights on PLC I/O card so at least that is working. If I disconnect the green cable from the valve itself I can hear the change in position for one of the axis, on the other one there is nothing. 

What else can I try?

What can be causing this problem?

Thanks in advance for any help

Thank you both for the help.

Manage to solve both problems and the machine is running again.

*X2: a blown fuse on the control card...it blew when I swapped the connectors on the valves trying to see if the other valve is working (looking into the reason for this since rating on both fuses is the same)

*X3: defective valve
