11 Intervention in the Course of Program Execution
11.1 Conditional Block Skip
If at the beginning of block con-
ditional block skip /n is pro-
grammed (n means the number
of the conditional block switch),
than
– if switch No. n is on, it skips
block,
– if switch No. n is off, it exe-
cutes block.
The conditional block switch
No. 1 can be reached on
OPERATOR’S PANEL or
POSITION screens. After
pressing the action menu key,
F5
CONDITIONS action menu
must be selected, than switch
COND. BLOCK (conditional block) needs to be pressed.
If NCT machine control board is used select button.
The control can handle another 8 conditional block switches (altogether 9). These switches can
be optionally used.
11.2 Increasing Feedrate by Means of Rapid Traverse Jog Button
If axes are moved during program execution and rapid traverse jog button is pressed,
the control increases feedrate, if rapid traverse jog button is released, it resets the programmed
feedrate.
The measure of acceleration is determined by the value fixed at parameter 1371 FMULT. The
programmed value is multiplied by the number fixed at parameter, and the result is activated as
feedrate. If the value of parameter is 1 the feedrate remains unchanged when pressing rapid
traverse button, if the value is e.g. 2 it is doubled.
