4. DESCRIPTION OF PARAMETERS
B–63610EN/01
74
CSD In the function for automatically reducing a feedrate at corners,
0 : Angles are used for controlling the feedrate.
1 : Differences in feedrates are used for controlling the feedrate.
G8S Serial spindle look–ahead control is:
0 : Disabled.
1 : Enabled.
When enabled, look–ahead control can be applied to the following
functions:
D Rigid tapping
D Cs contour control
D Spindle positioning (only when bit 3 of parameter No.1800 is 1)
NOTE
1 FAD (fine acceleration/deceleration) cannot be applied to
the spindles. When serial spindle look–ahead control is
applied, therefore, FAD cannot be used for the servo axes.
2 For Cs contour control, look–ahead control is valid only for
the first spindle. Cs contour control with the second spindle
does not support look–ahead control.
LS2 Acceleration/deceleration after interpolation for cutting feed in
look–ahead control mode is:
0 : Exponential acceleration/deceleration.
1 : Linear acceleration/deceleration. (The function for linear acceleration/
deceleration after interpolation for cutting feed is required.)

[Data type] Bit
PRT The acceleration/deceleration of interpolation–type rapid traverse is
performed:
0: With a constant inclination.
1: With a constant time.
NOTE
This parameter is invalid if the function of bell–shaped
acceleration/deceleration after rapid–traverse
interpolation is provided. The acceleration/deceleration
time constant and override for rapid traverse are used.
RBL In the AI look–ahead control mode, acceleration/deceleration of rapid
traverse is:
0: Linear acceleration/deceleration.
1: Bell–shaped acceleration/deceleration.
NOTE
Bit 4 (PRT) of parameter No. 1603 is invalid.
