The controller operation state changes momentarily according to the program contents or signals from the 
operation panel or machine. The controller roughly classifies the operation state into power OFF, not ready, 
and ready. 

 

Operation is enabled only in the operating preparation ready state. The operating preparation ready state is 
furthermore classified into reset, automatic operation stop, automatic operation start, and automatic 
operation pause as shown below: 

 

Manual mode operation is enabled in the operation complete state.
