[Classification] Input signal
[Function]
These signals can be used to select the override for the rapid traverse rate,
independently of the CNC, by setting bit 2 (OVE) of parameter No. 8001.

F0 is the minimum feedrate specified with parameter No. 1421.
[Classification] Input signal
[Function] These signals can be used to perform dry run or manual rapid traverse,
independently of the CNC, by setting bit 2 (OVE) of parameter No. 8001.
When the dry run signal DRNE is set to “1”, the specified rapid traverse
rate and cutting feedrate are ignored and the tool moves at the dry run
speed (set in parameter No. 1410) multiplied by the specified override.
Bit 3 (RDE) of parameter No. 8001 can be used to specify whether to
enable or disable dry run for rapid traverse.
When the manual rapid traverse selection signal RTE is set to “1” during
dry run, the tool moves at the rapid traverse rate for rapid traverse and at
the maximum jog feedrate for cutting feed. When the signal is set to “0”,
the tool moves at the jog feedrate. When the dry run signal DRNE is set
to “0”, the specified rapid traverse rate or cutting feedrate is restored.
