interpolation for linear rapid traverse, or acceleration change time of
bell-shaped acceleration/deceleration in optimum torque
acceleration/deceleration
[Input type] Parameter input
[Data type] 2-word path
[Unit of data] msec
[Valid data range] 0 to 200
(1) Set an acceleration change time of bell-shaped acceleration/
deceleration for linear rapid traverse (time for changing from the
state of constant feedrate (A) to the state of constant
acceleration/deceleration (C) at the acceleration rate calculated
from the acceleration rate set in parameter No. 1671: time of (B)
in the figure below).
(2) Set an acceleration change time of bell-shaped acceleration/
deceleration in optimum torque acceleration/deceleration (time
for changing from the state of constant feedrate (A) to the state of
acceleration/deceleration (C) at the acceleration rate calculated
from optimum torque acceleration/deceleration: time of (B) in
the figure below).
Feedrate in tangent direction
Maxim um acceleration rate not exceeding
maximum allowable acceleration rate set by
parameter No. 1671 for each axis is
autom atically calculated.
