# 6 FNW When the feedrate is determined according to the feedrate difference
and acceleration in AI contour control:
0: The maximum feedrate at which the allowable feedrate
difference and acceleration for each axis are not exceeded is
used.
1: The maximum feedrate at which the allowable feedrate
difference and acceleration for each axis are not exceeded is used.
The feedrate is determined so that the decreased feedrate is
constant regardless of the move direction when the profile is the
same.
A feedrate is determined to satisfy the condition that the allowable
feedrate difference and allowable acceleration rate of each axis are not
exceeded, and also to ensure that a constant deceleration rate is
applied to the same figure regardless of the direction of movement.
# 7 FCC When there is an axis that requires one or more seconds for
acceleration in acceleration/deceleration before look-ahead
interpolation:
0: Emphasis is placed on precision, so that the specified feedrate
may not be reached.
1: Emphasis is placed on speed, so that the specified feedrate is
produced.
When this parameter is set to 1, the precision of curved interpolation
such as circular interpolation and NURBS interpolation may decrease.
