(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.
