When 0 is set in parameter No.1770 or parameter No.1771,
linear acceleration/deceleration before interpolation is
disabled.
1771
Parameter 2 for setting the acceleration rate of linear acceleration/deceleration
before interpolation in advanced preview control, AI advanced preview control, or
AI contour control mode (time until the maximum machining speed is reached
during linear acceleration/deceleration before interpolation)
[Data type] Word
[Unit of data] msec
[Valid data range] 0 to 4000
This parameter is used to set the acceleration rate of linear acceleration/
deceleration before interpolation in advanced preview control, AI ad-
vanced preview control, or AI contour control mode. In this parameter, set
the maximum machining speed during linear acceleration/deceleration
before interpolation. In this parameter, set the time (time constant) used to
reach the speed set in parameter No.1770.
NOTE
1 When 0 is set in parameter No.1770 or parameter No.1771,
linear acceleration/deceleration before interpolation is
disabled.
2 In parameter Nos. 1770 and 1771, set values that satisfy the
following:
Parameter No.1770/Parameter No.1771 w 5
3 If 0 is set in parameter No. 1770 or 1771 in AI advanced
preview control or AI contour control, P/S alarm 5157 is
issued.
