2.5.2 Non linear interpolation type positioning
In the non-linear interpolation type positioning, the route is different between in forward
movement and in backward movement.
Notice: Please use the interpolation type positioning to ward off danger. (Set
the parameter LPR(No.1401#1) to "1")
2.5.3 Threading in forward movement
Threading is always executed at 100% override speed. That is to say, a pulse generated by a
manual handle is disregard in executing a threading block. In thread cutting cycle, the
pulse is invalid at the time actually cutting thread, but the one are valid in the other
movements.
2.5.4 Multiple command of auxiliary function
The second and third M-codes in backward movement are output as the same codes in
forward movement.
2.5.5 Macro
In macro statement, the setting, operation, and so on of the macro variable is executed in
only first forward movement. That is to say, the setting, operation, and so on of the macro
variable is never executed in the block executing them once.
2.5.6 Program number block
The movement command in the block of the program number cannot be executed backward.
It is necessary to divide the program number block and the movement block into two.
2.5.7 Thread cutting retract
If the thread cutting retract is done in forward movement, interrupt the execution of the
program by reset, and execute the program from the head of the program.
