Additive compensation G149
The Control manages 16 tool-independent compensation values. One
G149 followed by a D number activates the additive compensation
function. G149 D900 deactivates the additive compensation function.
The compensation values are managed in the Program Run mode (see
"Program Run mode" in the User's Manual).
Programming:
 The compensation becomes effective after the tool has moved in
the compensation direction by the compensation value. Therefore,
program G149 one block before the block containing the path of
traverse to which the compensation is to apply.
 Additive compensation remains in effect up to:
 the next G149 D900
 the next tool change
 End of program

Parameter
D Additive compensation (default: D900):
 D900: deactivates the additive compensation
 D901 to D916: activates the additive compensation
The additive compensation is added to the tool
compensation.
