4. DESCRIPTION OF PARAMETERS
67
1624
Time constant of exponential acceleration/deceleration or bell–shaped accelera-
tion/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(exponential acceleration/deceleration in jog feed)
0 to 512 (linear acceleration/deceleration after interpolation in jog feed)
Set the time constant used for exponential acceleration/deceleration or
linear acceleration/deceleration after interpolation in jog feed fot each
axis. The type to select depends on the settings of the parameters CTLx,
and JGLx (Nos. 1610#0 and #4).
1625 FL rate of exponential acceleration/deceleration in jog feed for each axis.

Rotaion axis 1 deg/min 6 to 15000 6 to 12000
Set the lower limit (FL rate) of exponential acceleration/deceleration in
cutting feed for each axis.
1626
Time constant of exponetial acceleration/deceleration in the thread cutting cycle
for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 4000
Set the time constant used for exponential acceleration/deceleration in the
thread cutting cycle (G76, G92 (G78 in G code system B/C)) for each axis.
If the acceleration type is not exponential acceleration/deceleration,
parameter No. 1622 becomes valid.
