MAKINO SEIKI machine, model MSA50S 3 months ago is still working normally
After 3 months, the factory stopped production and reopened, the error "1906 atc sv alarm" appeared.
When the error is still home the machine is ok, but the main shaft does not run, the cooling water does not run.
I have checked all the position switches and they are still good.
Hope someone can help me to fix it
