B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 97 -
NOTE
1 In advanced preview control and AI advanced
preview control modes, parameter No. 1774
cannot be used.
2 To perform bell-shaped acceleration/deceleration,
set the following parameter:
AI advanced preview control and AI contour
control: Bit 6 (RBL) of parameter No. 1603 = 1
3 When acceleration/deceleration before
interpolation is set for rapid traverse, linear
interpolation type positioning is performed.
When the following parameters are set,
acceleration/deceleration before interpolation is
performed:
AI advanced preview control and AI contour
control: Bit 1 (AIR) of parameter No. 7054 = 0
Alternatively, bit 1 (LRP) of parameter No. 1401 =
1 and bit 1 (AIR) of parameter No.7054 = 1
1775 (Must not be used)*(Always set 0.)
1776 (Must not be used)*(Always set 0.)
1777
Minimum speed for the automatic corner deceleration function (for advanced
preview control, AI advanced preview control, or AI contour control)

Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Set a speed at which the number of buffered pulses in deceleration is
assumed to be 0 when linear acceleration/deceleration before
interpolation is used.
1779
Critical angle subtended by two blocks for automatic corner deceleration (for
advanced preview control, AI advanced preview control, or AI contour
control)
[Data type] 2-word
[Unit of data] 0.001 deg
[Valid data range] 0 to 180000
Set a critical angle to be subtended by two blocks for corner
deceleration when the angle-based automatic corner deceleration
function is used.
The angle subtended by two blocks is defined as q in the examples
shown below.
