After 'IF' only the condition is permissible.

Description

In the same NC block, a control block instruction was programmed with further NC commands. After a $IF instruction, only the corresponding condition may be programmed.

Example:

Wrong:

N10   G00 X0 Y0 Z0 P1=0

N20   $IF P1==1 X100 G01 F1000

N30     Y200

N40   $ENDIF

:

N1000 M30

Correct:

N10   G00 X0 Y0 Z0 P1=0

N20   $IF P1==1

N25     X100 G01 F1000

N30     Y200

N40   $ENDIF

:

N1000 M30
