- 645 -
1663 Allowable acceleration in the deceleration function based on the
acceleration of fine HPCC 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 allowable acceleration that may occur due to changes in the direction of
tool travel.
For an axis for which this parameter is set to 0, the deceleration function based on
the acceleration is disabled. If 0 is set for all axes, the feedrate is not determined
based on the acceleration.
In the 15B, the time for the maximum cutting rate (parameter No. 1422) was set for
arameter No. 1643 to set the allowable acceleration. In the 15i, on the other hand
the acceleration is directly specified for this parameter.
