4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
B Cutting feed override code m
[Function]
This is a signal to apply an override (magnification) to the cutting feedrate (F speed) during automatic operation.
[Operation]
In the cutting feed during automatic operation, the actual feedrate is the obtained by multiplying the commanded speed by
override value specified by this signal.
However, the override is 100% regardless of this signal, in the following cases:
 When the "Override cancel" signal (OVC) is ON.
 During tapping mode.
 During thread cutting.
These signals (*FV1 to 16) are set with the code method. The following table shows the relationship.

Generally, a rotary switch (5-step, 21-notch, compliment
binary code output) is connected to the operation board
and used between 0% and 200%.
When *FV1 to *FV16 are all OFF, the previous value is
retained. The value will change to 0% when the power
is turned OFF.
