- 477 -
NOTE
1 To this feedrate setting (100%), a rapid traverse
override (F0, 25, 50, or 100%) is applicable.
2 For automatic return after completion of reference
position return and machine coordinate system
establishment, the normal rapid traverse rate is used.
3 As a manual rapid traverse rate before machine
coordinate system establishment by reference
position return, the jog feedrate or manual rapid
traverse rate can be selected with bit 0 (RPD) of
parameter No. 1401.

1424: Manual rapid traverse rate
*1 : By using bit 2 (JZR) of parameter No. 1401, the
jog feedrate can be used for manual reference
position return at all times.
*2 : When bit 0 (RPD) of parameter No. 1401 is set to
1, the setting of parameter No. 1424 is used.
*3 : When rapid traverse is used for reference position
return without dogs or manual reference position
return after reference position establishment,
regardless of the deceleration dog, the feedrate
for manual reference position return based on
these functions is used (the setting of bit 1 (DLF)
of parameter No. 1404 is followed).
