- 710 -
-Look-ahead acceleration/deceleration before interpolation (or fine
HPCC) mode is currently set.
-The conditions for look-ahead acceleration/deceleration before
interpolation are satisfied.
If the conditions listed above are not satisfied,
acceleration/deceleration after interpolation is applied.
1671 Maximum allowable acceleration for each axis in acceleration/deceleration
before interpolation to linear type rapid traverse
[Input type] Parameter input
[Data type] Real number axis
[Unit of data] mm/sec/sec, inch/sec/sec, degrees/sec/sec (machine unit)
[Minimum unit of data] The increment system of the axis in question is followed.
[Valid data range] See the standard parameter setting table (D).
(For millimeter machines, 0.0 to +100000.0; for inch machines, 0.0 to
+10000.0)
This parameter sets the maximum allowable value of
acceleration/deceleration before interpolation to linear type rapid
traverse. If a value in excess of 100000.0 is set, the acceleration is
clamped to 100000.0.
If 0 is set, the following value is assumed:
1000.0 mm/sec/sec
100.0 inch/sec/sec
100.0 degrees/sec/sec
If 0 is set for all axes, acceleration/deceleration before interpolation is
not performed.
1672 Acceleration change period of bell-shaped acceleration/deceleration before
interpolation to linear type rapid traverse
[Input type] Parameter input
[Data type] Integer
[Unit of data] msec
[Valid data range] 0 to 200
This parameter sets the acceleration change period of bell-shaped
acceleration/deceleration before interpolation to linear type rapid
traverse (the period during which the acceleration changes from
constant feedrate state (A) to constant acceleration/deceleration state
(C) with the acceleration calculated based on the acceleration value set
in parameter No. 1671: portion (B) in the following figure).
