4.DESCRIPTION OF PARAMETERS B-64120EN/01
- 96 -
1773
Time constant T of rapid traverse linear acceleration/deceleration for each
axis or time constant T
1
of rapid traverse bell-shaped
acceleration/deceleration for each axis in AI contour control mode
[Data type] Word axis
[Unit of data] msec
[Valid data range] 0 to 4000
Set the time constant of rapid traverse acceleration/deceleration in AI
contour control mode.
(1) When bit 6 (RBL) of parameter No. 1603 is set to 1 (when
bell-shaped acceleration/deceleration is set)
Set time constant T
1
of bell-shaped acceleration/deceleration in
this parameter, and set time constant T
2
in parameter No. 1774.
(2) When bit 6 (RBL) of parameter No. 1603 is set to 0 (when linear
acceleration/deceleration is set)
Set time constant T of linear acceleration/deceleration in this
parameter, and set 0 in parameter No. 1774.
For an axis for which 0 is set in this parameter, the value set in
parameter No. 1620 is used.
NOTE
In advanced preview control and AI advanced
preview control modes, parameter No. 1773 cannot
be used.
1774
Time constant T
2
of rapid traverse bell-shaped acceleration/deceleration for
each axis in AI contour control mode
[Data type] Word axis
[Unit of data] msec
[Valid data range] 0 to 512
For each axis, set time constant T
2
of rapid traverse bell-shaped
acceleration/deceleration in AI contour control mode. For an axis for
which 0 is set in this parameter, the value set in parameter No. 1621 is
used.
