Restrictions
- Conditions for acceleration/deceleration before interpolation
When the conditions listed below are all satisfied,
acceleration/deceleration before interpolation becomes valid for rapid
traverse. The acceleration used is set to the maximum value that does
not exceed the maximum allowable acceleration for each axis, as set in
parameter No. 1671.
(1) Bit 5 (FRP) of parameter No. 1603 = 1
(2) Bit 4 (LRP) of parameter No. 1400 = 1: Linear interpolation type
positioning
(3) A non-zero value is set for any axis in parameter No. 1671.
(4) Look-ahead acceleration/deceleration before interpolation (or
fine HPCC) mode is currently set.
(5) The conditions for look-ahead acceleration/deceleration before
interpolation are satisfied.
When acceleration/deceleration before interpolation becomes valid,
acceleration/deceleration after interpolation set in Table 7.2.5 (a) is
disabled. This means that only acceleration/deceleration before
interpolation is applied.
If the above conditions are not satisfied, acceleration/deceleration after
interpolation set in Table 7.2.5 (a) becomes valid.

# 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.
