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.
NOTE
To use bell–shaped acceleration/deceleration after
interpolation, set this parameter to 0 and select the
acceleration/deceleration using CTBx, bit 1 of parameter
No. 1610.

CTBx Acceleration/deceleration in cutting feed including feed in dry run
0 : Exponential acceleration/deceleration or linear acceleration/decel-
eration after interpolation is applied (depending on the setting in
CTLx, bit 0 of parameter No. 1610).
1 : Bell–shaped 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 or bell–shaped
acceleration/deceleration after interpolation is applied (depending on
which is used for cutting feed).
