- 102 -
1621 FL feedrate for linear or bell-shaped acceleration/deceleration for rapid
traverse along each axis
[Input type] Parameter input
[Data type] Realaxis
[Unit of data] mm/min, inch/min, degree/min (machine unit)
[Minimum unit of data] Depend on the increment system of the applied axis
[Valid data range] Refer to the standard parameter setting table (C)
(When the increment system is IS-B, 0.0 - +240000.0)
Specify the FL feedrate for linear or bell-shaped acceleration/
deceleration or rapid traverse along each axis.
Example: Linear type

: Value set in parameter No. 1636
NOTE
When the feedrate is decelerated to the value set in
this parameter at any point regardless of whether
during a linear or nonlinear feedrate increase, the
tool moves at that feedrate for the remaining
distance then stops.
