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.
