I need help with Komatsu press brake PHS 35x125. The machine off around 6 months during Covid19 virus and previously it's working good.
This week I plan start production and the machine won't work.

If we select "Inch" mode, the ram is ok moving up and down.
But when we select " Single" or "Cycle" the ram no moving at all.

Please help to solve the issue.
Any manual book, electrical diagram etc very appreciated.
