- 577 -
1665 Allowable acceleration in the deceleration function based on the
acceleration during circular interpolation for each axis (for normal mode)
[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 in the deceleration function based on
the acceleration during circular interpolation for each axis.
The feedrate is controlled so that the acceleration resulting from changes
in the direction of travel during circular interpolation does not exceed
the value of this parameter.
For an axis for which 0 is set for this parameter, the acceleration
function based on the acceleration is disabled.
If different values are set for this parameter for different axes, the
feedrate is determined based on the lower acceleration of the specified
two circular axes.
This parameter is effective when fine HPCC mode is not used (ordinary
mode). In fine HPCC mode, parameter No. 1663 is used.
The "deceleration function based on the acceleration during circular
interpolation" is equivalent to the "feedrate clamp with the arc radius" in
the 15B.
In the 15B, the upper feedrate limit, lower feedrate limit, and arc radius
were specified for parameters Nos. 1490 to 1492. In the feedrate clamp
based on the acceleration in the 15i, the allowable acceleration is set for
this parameter.
NOTE
During involute interpolation, this parameter is applied to the
allowable acceleration for the "acceleration clamp in the vicinity
of the basic circle" of involute interpolation automatic feedrate
control.
