5.6 Traversing with feedforward control, FFWON, FFWOF
Function
Using feedforward control the velocity-dependent overtravel in path traversing is reduced to
zero. Traversing with feedforward control permits higher path accuracy and thus improved
machining results.
Programming
FFWON
Or
FFWOF
Parameters
FFWON
Activate feedforward control
FFWOF
Deactivate feedforward control
Note:The type of feedforward control and the path axes to which feedforward is to be applied
are determined via machine data.
Default: Velocity-dependent feedforward control
Option: Acceleration-dependent feedforward control (not possible with 810D)
Example
N10 FFWON
N20 G1 X… Y… F900 SOFT
