Manual Handle Retrace
Specifications
5/40
2.1.3 Forward movement and backward movement with a manual handle
The program is executed forward when a manual handle is turned to the positive direction.
And, the program is executed backward when a manual handle is turned to the negative
direction.
The program is executed backward as soon as a manual handle is turned to the negative
direction in executing the program forward.
When a manual handle keeps being turned in a negative direction, the program is executed
backward and the execution stops in the block of O number. Then, if a manual handle is
turned to the positive direction, the program is executed forward again.
Even if a manual handle controls the program execution, the program is executed forward
in no relation to a pulse generated by a manual handle on setting the manual handle check
signal to "0".
2.1.4 Program end
When the block of M2 or M30 is executed, the manual handle retrace ends. It is not possible
to execute the program backward from the block of M2 or M30.
When the execution of the program ends, the checking mode signal and the manual handle
check signal must be set to "0".
In 2 path control system, FIN signal must not be set to "1" when the block of M2 or M30 is
executed in only one of paths. After the block of M2 or M30 has been executed in both paths,
FIN signal is set to "1". (Except for the block of waiting M code is commanded before M2 or
M30 in both paths.)
2.1.5 Notice of the operation
• Dry-run can not operate during the checking mode. Dry-run signal must be set to "0".
• Automatic operation starts immediately with the feedrate commanded by the program,
when the checking mode signal or the synchronous operation with handle signal is
turned off during executing the program in the checking mode.
• The program must be executed from the head of it.
• The edit of the program and the change of the parameter and the offset must not be
done.
