14.2 Manual Speed Command
 Operation example 1 (When giving the manual speed command in automatic operation "run" of a
machining program)
(1) Search a machining program and execute the cycle start in memory mode.
(2) Command the automatic operation pause during the N200 block execution.
(3) Turn ON the "Manual speed command valid" and "Manual speed command reverse run valid" signals, as well as the han-
dle mode. (Keep the memory mode ON.)
(4) When 1st handle is rotated in the (+) direction, the axis moves in the blocks with the handle feedrate.
(5) When the handle is rotated in the (-) direction, the movement is reversed against the program. The reversed movement
ends at the block start point. (Cannot return to the previous block.)
(6) The handle, which keeps rotating in the (+) direction after the block has ended, continues the blocks N300 to N500 with
the handle feedrate.
(7) Command M30 at N600 block to end the program by NC reset or completion.
