Definitions
● Function number: 1
● Lower and upper limit value: -100, 100
● Gradient of the characteristic: a
● The operating point should be located at the center of the characteristic. Based on the
setpoint position of axis XA in the WCS at the instant that the function is defined in the NC
program, the characteristic must be shifted in the negative Y direction: a

Write online tool offset continuously (PUTFTOCF)

Using the predefined procedure PUTFTOCF(...), an online tool offset is executed based on a
polynomial function previously defined with FCTDEF(...) (Page 290).
Note
The online tool offset can also be realized using a synchronized action.
For further information, see Function Manual Synchronized Actions.
