- 711 -
1660 Maximum allowable acceleration of acceleration/deceleration before
interpolation for each axis
[Input type] Parameter input
[Data type] Realaxis
[Unit of data] mm/sec/sec, inch/sec/sec, degree/sec/sec (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 (D)
(When the machine system is metric system, 0.0 - +100000.0. When the
machine system is inch system, machine, 0.0 - +10000.0)
Specify the maximum allowable acceleration of acceleration/deceleration before
interpolation for each axis.
If a value greater than 100000.0 is set, it is clamped to 100000.0.
If 0 is set, it is regarded to be 100000.0. If 0 is set for all axes, look-ahead
acceleration/deceleration before interpolation will not be performed.
If the allowable acceleration for one axis is twice as large as that for another or
more, the feedrate may temporarily reduce around corners where the direction to
travel changes suddenly.

MBF Selects or cancels the multibuffer mode at power on and in the clear
state.
0: Cancels the multibuffer mode.
1: Selects the multibuffer mode. (When the optional multibuffer 15-block/100-
block function is not provided, five buffer blocks are used for the look-ahead
operation.)
When the multibuffer mode is selected, look-ahead acceleration/deceleration befor
interpolation is enabled at the same time.
If the fine HPCC option is provided, fine HPCC mode is enabled at the same time.
NOTE
This parameter becomes valid when the system is reset.
