Time (time constant) until the maximum machining speed is reached during linear
acceleration/deceleration before interpolation in advanced preview control,
AI advanced preview control, or AI contour control mode (for rotation axes)
[Data type] Word
[Unit of data] msec
[Valid data range] 0 to 4000
This parameter is used to set the acceleration rate (for rotation axes) of
linear acceleration/deceleration before interpolation in advanced preview
control, AI advanced preview control, or AI contour control mode.
This parameter sets the time (time constant) required to reach the speed set
in parameter No. 1770. The acceleration rate set by this parameter applies
to commands containing rotation axes. (The acceleration rate set by
parameter No. 1771 applies to commands not containing rotation axes.)
NOTE
If 0 is set in this parameter, the acceleration rate set in
parameter No. 1771 applies also to commands containing
rotation axes.

PSF In advanced preview control mode, AI advanced preview control mode,
or AI contour control mode, position switches are:
0 : Not used.
1 : Used.
NOTE
The position switch signals are output considering
acceleration/deceleration after interpolation and servo
delay. Acceleration/deceleration after interpolation and
servo delay are considered even for position switch signal
output in a mode other than advanced preview control mode,
AI advanced preview control mode, and AI contour control
mode. When this parameter is set to 1, however, signals are
output from the position switches at different times from the
specified ones.
