FCI EDR FD3 F1U
[Data type] Bit
F1U Specifies the units of the data for the parameters that set the feedrates
of the F1-digit feed commands (parameter Nos. 1451 to 1459).
Units of data
Increment system
When F1U is 0 When F1U is 1
Millimeter machine 0.1 mm/min 1 mm/min
Inch machine 0.001 inch/min 0.1 inch/min
Rotation axis 0.1 deg/min 1 deg/min
FD3 The number of significant digits of the fractional part in
the feedrate command (F command) for feed per revolution is:
0 : Up to two decimal positions (three decimal positions for inch
input).
1 : Up to three decimal positions (four decimal positions for inch
input).
EDR Selects a parameter for setting the external deceleration applied during
interpolation type rapid traverse (bit 1 (LRP) of parameter No. 1401 =
1) .
0 : Parameter No. 1426 is used for setting the external deceleration
rate applied during interpolation type rapid traverse.
1 : The first axis of parameter No. 1427 is used for setting the
external deceleration rate applied during interpolation type rapid
traverse.
Similarly, for external deceleration 2, 3, 4, and 5, the first axis of
the external deceleration rate parameter for rapid traverse is used
if EDR is set to 1.
FCI When the inch input and feed per revolution are set, the clamp
feedrate for cutting feed is set to:
0 : 9600 inch/min.
1 : 144000 inch/min.
