(4)If the only failure is in rapid traverse for positioning (G00), check the
following parameter settings and signals from the PMC.
a. Rapid traverse rate setting
1420 Individual–axis rapid traverse rate
b. Settings related to the rapid traverse override signal

*1 Fm is any value between 0% to 100%. It is specified in parameter No.
1412 (common to all axes).
*2 Fo is an absolute feedrate between 0 and the rapid traverse rate. It is
specified in parameter No. 1421 (for individual axes).

where Vi = 0 if *RViB = 1, and Vi = 1 if *RViB = 0.
That is, each signal has the following weights:
*RV0B : 1% *RV4B : 16%
*RV1B : 2% *RV5B : 32%
*RV2B : 4% *RV6B : 64%
*RV3B : 8%
If all signals are 0, the override value is assumed to be 0%, similarly to
when all signals are 1. If an attempt is made to specify a value greater than
100% as the override value, 100% is assumed.
The override type to use is specified with the following parameter.

ROV
Parameter input
[Data type] Bit
ROV Specifies the override type as follows:
0 : Two input signals, ROV1 and ROV2, are used to specify the override
value as FO, Fn, 50%, or 100%.
1 : Seven input signals, *RV0B to *RV6B, are used to specify the
override value as any integer value between 0% and 100% (in 1%
steps).
