4.DESCRIPTION OF PARAMETERS B-64120EN/01
- 100 -
1785
Parameter for determining an allowable acceleration when the feedrate is set
by acceleration
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 32767
This parameter sets the time required to attain the maximum cutting
feedrate to determine the allowable acceleration when the feedrate is
determined by acceleration in AI advanced preview control mode or
AI contour control mode.
The maximum cutting feedrate and the data set in this parameter are
used to determine the allowable acceleration. As the maximum
cutting feedrate parameter, parameter No.1432 (maximum cutting
feedrate in AI advanced preview control mode or AI contour control
mode) is used.

1786
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.
