FWB Cutting feed acceleration/deceleration before interpolation
0 : Type A of acceleration/deceleration before interpolation is used.
1 : Type B of acceleration/deceleration before interpolation is used.
Type A:
When a feedrate is to be changed by a command, acceleration/
deceleration starts after the program enters the block in which the
command is specified.
Type B:
When a feedrate is to be changed by a command, deceleration
starts and terminates at the block before the block in which the
command is specified.
When a feedrate is to be changed by a command, acceleration
starts after the program enters the block in which the command is
specified.

COV The outer arc cutting feedrate change function of the automatic corner
override function is:
0 : Not used.

BS2 The type of acceleration/deceleration after interpolation in cutting feed
in advanced preview control mode is:
0 : Specified by bit 6 (LS2) of parameter No. 1602.
