• While the part program is being executed, a "Program running" display
appears in the mode field.
• If, during program execution, FEED HOLD is activated, FST (Feed stop) is
displayed in the status field and the feed drives are brought to a standstill
while maintaining the programmed path movement.
• In the case of NC STOP the NC STOP display appears in the mode field.
If the RESET key is pressed, execution of the part program is terminated.
• The control is put into the "RESET" state:

− All buffers and active memories are cleared (however, the part program
memory contents are preserved).
− The control is in the Reset position and ready to run a new program.
• "Program reset" is displayed in the mode field.
• Error messages with the delete condition "Reset" are deleted.
