7. FEEDRATE CONTROL/ACCELERATION
AND DECELERATION CONTROL
640
NOTE
This parameter is effective only when the function of
bell-- shaped acceleration/deceleration after interpolation in
cutting feed is provided. If the function is not provided, the
setting in CTLx, bit 0 of parameter No. 1610, determines the
type of acceleration/deceleration irrespective of the setting
in this parameter.
JGLx Acceleration/deceleration in manual continuous feed (jog feed)
0 : Exponential acceleration/deceleration is applied.
1 : Linear acceleration/deceleration after interpolation or bell--shaped
acceleration/deceleration after interpolation is applied (depending on
which is used for cutting feed).
1620
Time constant used for linear acceleration/deceleration or bell--shaped
acceleration/deceleration in rapid traverse for each axis
[Data type] Word axis
[Unitofdata] ms
[Valid data range] 0 to 4000
Specify a time constant used for acceleration/deceleration in rapid tra-
verse. When the optional function of bell--shaped acceleration/decelera-
tion in rapid traverse is provided, bell--shaped acceleration/deceleration is
applied in rapid traverse. If the function is not provided, linear accelera-
tion/deceleration is applied.
(1)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.
(2)When the function is not provided, specify a time constant used in
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 applie d in rapid
traverse even if the function is provided. In this case, this
parameter stands for a time constant used in linear
acceleration/deceleration in rapid traverse.
1622
Time constant of exponential acceleration/deceleration or linear acceleration/
deceleration after interpolation or bell--shaped acceleration/deceleration
after interpolation, in cutting feed for each axis
[Data type] Word axis
[Unitofdata] ms
[Valid data range] 0 to 4000 (For exponential acceleration / deceleration)
0 to 512 (For linear acceleration / deceleration after interpolation or
bell--shaped acceleration/deceleration after interpolation)
