Multiple feedrate values in one block
Function
The "Several feedrates in one block" function can be used independent of external analog
and/or digital inputs to activate
●
Different feedrates of an NC block,
●
dwell time, and
●
Retraction
in synchronism with the movement.
The hardware input signals are combined in one input byte.
Programming
F2=... F3=...
In addition to the path feed, you can program up to 2
further feedrates in the block; non-modal
ST=...
Dwell time (for grinding technology: sparking-out time);
non-modal
SR=...
Return path; non modal. The unit for the retraction path
refers to the current valid unit of measurement (mm or
inch).
FMA [2,x] =...
FMA[3,x]=...
In addition to the path feed, you can program up to 2
further feedrates per axis in the block; non modal
STA=...
Axial dwell time (for grinding technology: sparking-out
time); non-modal
SRA=...
Axial return path; non-modal
FMA and F value
The axial feedrate (FMA value) or path feedrate (F value) corresponds to 100% feedrate.
You can use this function to realize feedrates that are smaller than or equal to the axial
feedrate or the path feedrate.
