# 5 FRP To linear type rapid traverse:
0: Acceleration/deceleration after interpolation is applied.
The type of acceleration/deceleration after interpolation is
determined by bit 0 (REX) of parameter No. 1600, bit 7 (NEX) of
parameter No. 1600, and bit 5 (RTB) of parameter No. 1601.
1: Acceleration/deceleration before interpolation is applied.
The maximum allowable acceleration for each axis is set in
parameter No. 1671.
When using bell-shaped acceleration/deceleration before
interpolation, set the acceleration change period in parameter No.
1672.
When this parameter is set to 1, acceleration/deceleration before
interpolation is also applied to rapid traverse if the conditions listed
below are all satisfied. In this case, acceleration/deceleration after
interpolation is not applied.
- Bit 4 (LRP) of parameter No. 1400 = 1: Linear interpolation type
positioning
- A non-zero value is set for any axis in parameter No. 1671.
- 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.
