during the forward run.

"In automatic operation "pause"" (SPL) is OFF or in the automatic operation pause: "In automatic operation "run"" (OP)

is ON, "In automatic operation "start"" (STL) is OFF, "In automatic operation "pause"" (SPL) is ON

- The "Reverse run" (VRV) signal is ON

 If the "Automatic operation "start" command" signal is turned ON and OFF during the automatic operation stop, the reverse

run starts from the block stop point.

reverse run starts after the execution for the remaining distance of the command. Therefore, the reverse run usually must

be started during the automatic operation stop.
