The method of deceleration based on the feedrate difference differs depending on
the setting made for parameter FNW (bit 6 of No. 19500).
If "0" is set, the largest feedrate that does not exceed the permissible feedrate
difference set for parameter No. 8410 is assumed to be the deceleration feedrate.
In this case, the deceleration feedrate differs if the travel direction differs, even if
the shape is the same.
Deceleration to
500 mm/min
Deceleration to
354 mm/min
(Example)
If parameter FNW (bit 6 of No. 19500) = 0 and the
permissible feedrate difference = 500 mm/min (on all axes)
If "1" is set, the feedrate is determined not only with the condition that the
permissible feedrate difference and permissible acceleration on each axis are not
exceeded, but also that the deceleration feedrate is constant regardless of the
travel direction if the shape is the same.
If 1 is set for this parameter, the deceleration feedrate determined with the
feedrate difference or acceleration may be up to 30% lower than that determined
if 0 is set.
Deceleration to
354 mm/min
Deceleration to
354 mm/min
(Example)
If parameter FNW (bit 6 of No. 19500) = 1 and
permissible feedrate difference = 500 mm/min (on all axes)
