(24) Negative-direction overtravel signal EOTNg <F130.6, F133.6, F136.6, F139.6>
(25) Positive-direction overtravel signal EOTPg <F130.5, F133.5, F136.5, F139.5>
[Classification] Output signal, group-by-group signal
[Function] Indicates the overtravel state.
[Operation] These signals are set to "1" when an overtravel alarm is detected. When the stroke
limit in the negative direction is exceeded, signal EOTNg is set to "1". When the
stroke limit in the positive direction is exceeded, signal EOTPg is set to "1".
Simultaneously, alarm signal EIALg is set to "1".
These signals are set to "0" when the overtravel alarm is released and reset signal
ECLRg is set to "1". See "Alarm signal EIALg" for details of how to release an
overtravel alarm.
(26) Feedrate override signals *EFOV0g to *EFOV7g <G151 (, G163, G175, G187)>
[Classification] Input signal, path-by-path signal (group-by-group signal)
[Function] Applies cutting override.
[Operation] Like the CNC's feedrate override signals *FV0 to *FV7, these signals can be used
to select the override for the cutting feedrate, in steps of 1% from 0 to 254%,
independently of the CNC using the parameter OVE (No. 8001#2).
These signals form an eight-bit binary code and correspond to the override value as
follows:
∑

%2 valueOverride Vi
Vi = 0 when signal *EFOVi is 1
Vi = 1 when signal *EFOVi is 0
That is, each signal has the following significance:
*EFOV7 = 128%, *EFOV3 = 8% ,
*EFOV6 = 64%, *EFOV2 = 4% ,
*EFOV5 = 32%, *EFOV1 = 2% ,
*EFOV4 = 16%, *EFOV0 = 1%
When all signals are set to "0", the override is regarded as being 0%, as well as when all
signals are "1".
Bit 5 (IFV) of parameter No. 8005 is used to determine whether these signals are
path-by-path signals or group-by-group signals.
When the IFV parameter is set to 0, these signals are path-by-path signals. When the IFV
parameter is set to 1, these signals are group-by-group signals.
