D When the function 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.
D When the function is not provided, specify a time constant used for
linear acceleration/deceleration.
NOTE
When parameter No. 1621 (time constant T2 used for
bell–shaped acceleration/deceleration in rapid traverse) is
set to 0, linear acceleration/deceleration is applied in rapid
traverse even if the Bell–shaped acceleration/deceleration
in rapid traverse is provided. In this case, this parameter
stands for a time constant used for linear acceleration/
deceleration in rapid traverse.
1621
Time constant t T2 used for bell–shaped acceleration/deceleration
in rapid traverse for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 512
Specify time constant T2 used for bell–shaped acceleration/deceleration
in rapid traverse for each axis.
NOTE
1 This parameter is effective when the function of
bell–shaped acceleration/deceleration in rapid traverse is
provided. Set parameter No. 1620 to time constant T1 used
for bell–shaped acceleration/deceleration in rapid traverse,
and set this parameter to time constant T2.
For details of time constants T1 and T2, see the general
description in this section.
2 When this parameter is set to 0, linear acceleration/
deceleration is applied in rapid traverse. The setting in
parameter No. 1620 is used as a time constant in linear
acceleration/deceleration.
