4 Explanation of Interface Signals
4.4 PLC Output Signals (Data Type: R***)
Cont. Signal name
A 2nd cutting feed override
[Function]
When the "2nd cutting feed override valid" signal (FV2E) is used, another override can be exerted on the "Cutting feed
override code m" (*FV1 to *FV16), or on the "1st cutting feed override" (file register value) when the "Cutting feed override
method selection" (FVS) is set to file register method. Applicable range of the override is 0% to 327.67% in 0.01%
increments. The value is set in the file register in binary.
[Operation]
When this override function is used, the actual feedrate is the value obtained by multiplying commanded feedrate (F) by
the "1st cutting feed override" ratio and the "2nd cutting feed override" ratio.
Since the least increment of 2nd feedrate override is 0.01%, override setting "10000" corresponds to 100%.
The override ratio is fixed to 100%, irrespective of the "1st cutting feed override" or the "2nd cutting feed override" setting,
under the following condition:
 The "Override cancel" signal (OVC) is ON.
 During tapping in fixed cycle
 During TAPPING mode
 During thread cutting
Note
(1) Only when the 1st cutting feed override or the 2nd cutting feed override is 0% or both of them are 0%, override is
exerted not only on the cutting feedrate but on rapid traverse rate in automatic operation. That is, rapid traverse stops
as well as cutting feed if the cutting feedrate override is set to 0%. When override setting is 0%, "M01 OPERATION
ERROR" appears in the alarm display section of setting and display unit, and "M01 OPERATION ERROR 0102" in the
ALARM DIAGNOSIS display.
[Related signals]
(1) Cutting feed override code m (*FV1 to 16: YC60)
(2) Cutting feed override method selection (FVS: YC67)
(3) 2nd cutting feed override valid (FV2E: YC66)
(4) 1st cutting feed override (R2500)
Note
(1) For relationship among these signals, refer to the description for the cutting feedrate override.
Cont. Signal name
A Rapid traverse override
[Function]
When the "Rapid traverse override method selection" signal (ROVS) is set to "file register method", override can be
exerted, besides the code method override (ROV1, ROV2), by setting within the range of 0% to 100% by 1% increments.
Desired value is set to file register (R) in binary code.
[Operation]
During rapid traverse in the automatic or manual operation, the actual feedrate will be the result of multiplying the rapid
traverse speed set in a parameter by this override ratio.
Note
(1) The override will be clamped at 100%.
(2) The "M01 Rapid traverse override zero 0125" occurs when the override value is 0%.
[Related signals]
(1) Rapid traverse override code 1, 2 (ROV1, ROV2: YC68, YC69)
(2) Rapid traverse override method selection (ROVS: YC6F)
