1ST CUTTING FEEDRATE
—
OVERRIDE
(File register method)
[Function]
When "Cutting feedrate override method select " (FVS) is set to "file register method", override
(0~300%, 1% increment) can be exerted on the cutting feedrate. Desired value is set to file register
(R) in binary code.
[Operation]
When override is exerted to the preset feedrate, the true feedrate is the product obtained by
multiplying the preset feedrate by the specified override ratio (provided that "2nd cutting feedrate
override" is not valid).
The override ratio is fixed to 100%, irrespective of 1st cutting feedrate override setting, under the
following condition:
(1) "Override cancel" (OVC) signal is ON
(2) During tapping in fixed cycle
(3) During TAPPING mode
(4) During thread cutting
(Note) Only when override setting is 0%, override is exerted even on rapid traverse speed in
automatic operation. That is, cutting feed as well as rapid traverse stop if the 1st cutting
feedrate override is set to 0% during automatic operation. When override setting is 0%,
"M01 OPERATION ERROR" appears in the alarm display section of screen, and "M01
OPERATION ERROR 0102" in the ALARM DIAGNOSIS display.

(2) Cutting feedrate override method select (FVS: Y767)
(3) 2nd cutting feedrate override valid (FV2E: Y766)
(4) 2nd cutting feedrate override (file register method)
For relationship among these signals, refer to the description the cutting feedrate override.

2ND CUTTING FEEDRATE
—
OVERRIDE
(File register method)
[Function]
When the 2nd cutting feedrate override valid function (FV2E) is used, another override can be
exerted on feedrate overrided by "Cutting feedrate override" (*FV1~*FV16) in code feedrate method,
or by "1st cutting feedrate override (file register method)". The 2nd cutting feedrate override can be
set within range from 0% to 327.67% with 0.01% increment. Value of override ratio is set in binary
code system to file register.
