B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 83 -
1 : Bell-shaped acceleration/deceleration after interpolation is
applied.
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 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 T or T
1
used for linear acceleration/deceleration or
bell-shaped acceleration/deceleration in rapid traverse for each axis
[Data type] Word axis
[Unit of data] ms
[Valid data range] 0 to 4000
Specify a time constant used for acceleration/deceleration in rapid
traverse for each axis.
(1) When bell-shaped acceleration/deceleration is set
Set time constant T
1
for bell-shaped acceleration/deceleration in
this parameter, and set time constant T
2
in parameter No. 1621.
(2) When linear acceleration/deceleration is set
Set time constant T for linear acceleration/deceleration in this
parameter, and set 0 in parameter No. 1621.
NOTE
1 When parameter No.1621 (time constant T
2
used
for bell-shaped acceleration/deceleration in rapid
traverse) is set to 0, linear
acceleration/deceleration is applied 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.
2 Depending on the set time constant values, a
movement may be made at a feedrate a little lower
than the rapid traverse rate for a certain time
before the rapid traverse rate is attained by
acceleration. To prevent this, set the time
constants to a multiple of 8.
