 Operation example 1 (When the manual speed command is enabled at the second block in both the 1st
and 2nd part systems)
(1) Search a machining program and execute the cycle start of the 1st and 2nd part systems in memory mode.
(2) Command the automatic operation pause during the N102, N202 block execution.
(3) Turn ON the "Manual speed command valid" signal, "Manual speed command reverse run valid" signal, and handle mode
of the 1st and 2nd part systems. (Keep the memory mode ON.)
(4) When the 1st handle is rotated in the (+) direction, the axes in the blocks of the 1st and 2nd part systems continue to
move at speeds to which the ratio of the automatic operation feed rates is applied to the handle feedrates.
Feedrates of each part system are as below.
(Example) When the handle is rotated with the handle feedrate of 10.0mm/min:
Block N102 of the 1st part system: Command speed is F100, and feedrate is 5.0 (mm/min)
Block N202 of the 2nd part system: Command speed is F200, and feedrate is 10.0 (mm/min)
(5) When the handle is rotated in the (-) direction, the movement is reversed against the program. In this case, the ratio of the
automatic operation feed rates is applied to the handle feed rates.
However, when either of $1 or $2 reaches the block start point, the reversed movements of the both part systems end.
(Cannot return to the previous block.)
(6) The handle, which keeps rotating in the (+) direction after the block has ended, continues the blocks N103 to N105/N203
to N205 with the handle feed rate.
