不知道你说的什么系统? 840c里 有。
@736
With this command you can delete the distance to go within an NC block depending on the
signal state of an external input. With this command, an axis-specific distance to go can be
implemented for a positioning axis or for all the contouring axes within one function call.
The action of the function is non modal. One NC block can contain several delete distance to
go functions which, depending on the parameterization, affect either contouring axes or
positioning axes. The axis and its coordinate must be programmed before its @736 function.
@736 functions for the contouring axes and maximum 5 positioning axes can be programmed
in one block.
If several external inputs are to affect one axis, several @736 commands must be written for
the same axis. Please make sure that all the inputs which are to affect the same axis are in
one input byte.
Meaning:
Axis number 1...n for positioning axes
Axis number 0 for contouring axes
Channel address 0=CSB inputs
1=1st byte of the 1st MIXED I/O
2=2nd byte of the 2nd MIXED I/O
3=1st byte of the 2nd MIXED I/O
4=2nd byte of the 2nd MIXED I/O
Bit address 0..7 for MIXED I/O
6 or 7 when using CSB
plus sign when evaluating the positive edge
minus sign when evaluating the negative edge
