Hi everyone!
I have a problem when for some reason my H400 turn's hydraulic's off (weak eletricity power) I get NMI servo alarm. In that moment Y-axis starts falling down to the end of way causing collision between the tool and workpiece. Shouldn't there be any brake to stop it in that case? Just to mention that hydraulic is used as counter balance. Havent found any check valve to support it in hydraulic circuit diagram.
Any idea?
