- 106 -
1635 Time constant for cutting feed acceleration/deceleration after interpolation in
the mode of look-ahead acceleration/deceleration before interpolation
[Input type] Parameter input
[Data type] Integeraxis
[Unit of data] msec
[Valid data range] 0 - 4000
In the mode of look-ahead acceleration/deceleration before
interpolation and in fine HPCC mode, this parameter is used instead
of the ordinary time constant (parameter No. 1622) .
Be sure to always set the same time constant in this parameter for all
axes, except for a special application. Otherwise, correct linear or
circular figures cannot be obtained.
1636 Time constant for bell-shaped acceleration/deceleration for rapid traverse
along each axis (T2)
[Input type] Parameter input
[Data type] Integeraxis
[Unit of data] msec
[Valid data range] 0 - 1000
Set time constant T2 of bell-shaped acceleration/deceleration for
rapid traverse along each axis. Specify this parameter so that it does
not exceed the value of parameter No. 1620 (T1) .
1644 Parameter 1 to set acceleration/deceleration for each axis when a constant
feedrate command for PMC axis control is specified
[Input type] Parameter input
[Data type] Integeraxis
[Unit of data] min
