hi guys ,
i have a trumpf trumatic 225 single station punch press machine controlled with Siemens simumerik system 3 .
i have a problem with sinumerik , there's two outputs connected with the PLC inputs , and called NC ready for operation , one of them not existing .
when i try to feed it with 24V the machine can work by x,y axes only , but the main cylinder not work .
what could make the sinumerik not ready for operating ?

Thanks in advance ,
