7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL
313
Linear acceleration/deceleration after cutting feed interpolation is
enabled when the CTL (bit 0 of parameter No. 1610) set to 1. If
bell–shaped acceleration/deceleration after interpolation for cutting feed
is also enabled, bell–shaped acceleration/deceleration is executed. The
time constants for cutting feed and jog feed for each axis are specified in
parameter Nos. 1622 and 1624 respectively, in the same way as for
exponential acceleration/deceleration. The values specified for the FL
feedrate for cutting feed (parameter No. 1623) and the FL feedrate for jog
feed (parameter No. 1625) are ignored (always assumed to be 0).

[Data type] Bit axis
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 in cutting feed).
1622
Time constant of exponential acceleration/deceleration or linear acceleration/
deceleration after interpolation in cutting feed for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 4000 (For exponential acceleration/deceleration)
0 to 512 (For linear acceleration/deceleration after interpolation
Set the time constant used for exponential acceleration/deceleration or
linear acceleration/deceleration after interpolation in cutting feed for each
axis. Except for special applications, the same time constant must be set
for all axes in this parameter. If the time constants set for the axes differ
from each other, proper straight lines and arcs cannot be obtained.
1624
Time constant of exponential acceleration/deceleration or linear acceleration/
deceleration after interpolation, in jog feed for each axis.
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 4000 (For exponential acceleration/deceleration)
0 to 512 (For linear acceleration/deceleration after interpolation
Set the time constant used for exponential acceleration/deceleration or
linear acceleration/deceleration after interpolation in jog feed for each
axis.
The type of acceleration/deceleration is determined depending on the
setting in parameter No. 1610.
