(27) Override cancellation signal EOVCg <G150.5 (, G162.5, G174.5, G186.5)>
[Classification] Input signal, path-by-path signal (group-by-group signal)
[Function] Disables override.
[Operation] When override is enabled, independently of the CNC, by setting the
parameter OVE (No. 8001#2), setting this signal to "1" fixes the
cutting feed override to 100%. This signal does not affect the rapid
traverse override.
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.
(28) Rapid traverse override signals EROV1g, EROV2g <G150.0,1>
[Classification] Input signal, path-by-path signal
[Function] Applies rapid traverse override.
[Operation] These signals can be used to select the override for the rapid traverse
rate, independently of the CNC, by setting of the parameter OVE (No.
8001#2).

F0 is the minimum feedrate specified with parameter No. 1421.
(29) Dry run signal EDRN <G150.7>
(30) Manual rapid traverse selection signal ERT <G150.6>
[Classification] Input signal, path-by-path signal
[Function] Applies dry run, or chooses whether to apply dry run.
[Operation] These signals can be used to perform dry run or manual rapid traverse,
independently of the CNC, by setting the parameter OVE (No.
8001#2). When the dry run signal EDRN 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. Parameter RDE (No. 8001#3) can be used to
specify whether to enable or disable dry run for rapid traverse.
When the manual rapid traverse selection signal ERT 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 EDRN is set to "0", the specified rapid traverse rate or
cutting feedrate is restored.
