1622
Time constant of exponential acceleration/deceleration or bell–shaped accelera-
tion/deceleration after interpolation, or linear aceeleration/deceleration after
interpolation in cutting feed for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 4000(exponential acceleration/deceleration in cutting feed)
0 to 512 (linear acceleration/deceleration after interpolation in cutting
feed)
Set the time constant used for exponential acceleration/deceleration in
cutting feed or linear acceleration/deceleration after interpolation in
cutting feed for each axis. The type to select depends on the settings of the
parameter CTLx (bit 0 of No. 1610). 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.

Rotaion axis 1 deg/min 0,6 to 15000
Set the lower limit (FL rate) of exponential acceleration/deceleration in
cutting feed for each axis.
NOTE
Except for special applications, this parameter must be set
to 0 for all axes. If a value other than 0 is specified, proper
straight lines and arcs cannot be obtained.
1624 Time constant of exponential acceleration/deceleration 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)
Set the time constant used for exponential acceleration/deceleration in jog
feed fot each axis.
