CTLx Acceleration/deceleration in cutting feed including feed in dry run
0 : Exponential acceleration/deceleration is applied.
1 : Linear acceleration/deceleration after interpolation is applied.
JGLx Acceleration/deceleration in manual continuous feed (jog feed)
0 : Exponential acceleration/deceleration is applied.
1 : Linear acceleration/deceleration after interpolation is applied
(depending on which is used for cutting feed).

Time constant used for linear acceleration/deceleration or bell–shaped
acceleration/deceleration in rapid traverse for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 4000
(1)When the bell–shaped acceleration/deceleration in rapid traverse is
provided, set this parameter to time constant T1 used in bell–shaped
acceleration/deceleration in rapid traverse, and set parameter No.1621
to time constant T2.
(2)When the bell–shaped acceleration/deceleration in rapid traverse is
not provided, set this parameter to time constant used in linear
acceleration/deceleration, and set parameter No.1621 to “0”.
