F2=... to F7=... : In addition to the path feedrate, up to six further
feedrates can be programmed in the block. The
numerical expansion indicates the bit number of
the input that activates the feedrate when
changed:
Effective: Non-modal
ST=... : Dwell time in s (for grinding technology: sparking-
out time)
Input bit: 1
Effective: Non-modal
SR=... : Retraction path
The unit for the retraction path refers to the cur‐
rent valid unit of measurement (mm or inch).
Input bit: 0
Effective: Non-modal
FA[<Ax>]=... : The axial feedrate is programmed under the ad‐
dress FA and remains valid during the absence of
an input signal.
Effective: Modal
FMA[2,<Ax>]=...
to FMA[7,<Ax>]=...
: In addition to the axial feedrate FA
up to six fur‐ther feedrates per axis can be programmed in the
block with FMA. The first parameter indicates the
bit number of the input and the second the axis
for which the feedrate is to apply.
Effective: Non-modal
STA[<Ax>]=...: Axial dwell time in s (for grinding technology:
sparking-out time)
Input bit: 1
Effective: Non-modal
SRA[<Ax>]=...: Axial retraction path
Input bit: 0
Effective: Non-modal
<Ax>: Axis for which the feedrate is to apply
Note
Priority of the signals
The signals are scanned in ascending order starting at input bit 0 (I0). Therefore, the retraction
motion has the highest priority and the feedrate F7 the lowest priority. Dwell time and retraction
motion end the feedrate motions that were activated with F2 to F7.
The signal with the highest priority determines the current feedrate.
