Feedrate For Positioning Axes/Spindles (Fa, Fpr, Fpraon, Fpraof) - Siemens SINUMERIK 840Di sl Programming Manual

Feedrate Control and Spindle Motion

7.5 Feedrate for positioning axes/spindles (FA, FPR, FPRAON, FPRAOF)

7.5 Feedrate for positioning axes/spindles (FA, FPR, FPRAON, FPRAOF)
Function
Positioning axes, such as workpiece transport systems, tool turrets and end supports, are
traversed independently of the path and synchronized axes. A separate feedrate is therefore
defined for each positioning axis. Example: FA[A1]=500.
FPRAON can be used to axially activate the revolutional feedrate for positioning axes and
spindles, and FPRAOF can be used to deactivate the respective axis again.

Feedrate for the specified positioning axis in mm/min or inch/min or
deg/min
Positioning velocity (axial feed)
for the specified spindles in deg/min.
Identification of the rotary axis or spindle whose revolutional feedrate
programmed in G95 is to be used as the basis for the revolutional
feedrate of the path and synchronized axes.
Activate revolutional feedrate for positioning axes and spindles axially.
The first command identifies the positioning axis/spindle that is to be
traversed at a revolutional feedrate. The second command identifies
the rotary axis/spindle from which the feedrate must be derived.
Deactivate revolutional feedrate. Specification of axis or spindle that is
to stop traversing at a revolutional feedrate.
