F8A Valid data range for an F command with a decimal point
Increment system Units IS–A, IS–B
Millimeter input mm/min 0.001 to 99999.999.
Inch input inch/min 0.00001 to 999.99999.
Rotation axis (mm) deg/min 1 to 240000.
Rotation axis (inch) deg/min 1 to 9600.
Increment system Units IS–A, IS–B
Millimeter input mm/min 0.001 to 240000.
Inch input inch/min 0.00001 to 9600.
Rotation axis deg/min 1 to 240000.
FRV For inch input, the valid range of the feedrate specified for feed per
revolution is:
0 : Standard range. (F0.000001 to 9.999999 inches per revolution)
1 : Extended to F50.0 inches per revolution. (F0.000001 to 50.000000
inches per revolution)
EDR The external deceleration speed in liner interpolation type positioning is
set in:
0: Parameter No. 1426.
1: Parameter No. 1427, for the first axis.
FC0 Specifies the behavior of the machine tool when a block (G01, G02, G03,
etc.) containing a feedrate command (F command) that is 0 is issued
during automatic operation, as follows:
0: A P/S alarm (No.011) is displayed, and the block is not executed.
1: No alarm is displayed, and the block is executed.

When the machine requires little change in cutting feedrate during
cutting, a cutting feedrate can be specified in the parameter. This
eliminates the need to specify a cutting feedrate (F command) in the NC
program.
