NOTE
During involute interpolation, the minimum
allowable feedrate of "clamping of acceleration
near a basic circle" in involute interpolation
automatic feedrate control is used.
1737
Maximum allowable acceleration rate for the deceleration function based on
acceleration in AI contour control for each axis
[Input type] Parameter input
[Data type] Real axis
[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 to +100000.0. When
the machine system is inch system, machine, 0.0 to +10000.0.)
Set a maximum allowable acceleration rate produced by changing the
tool move direction.
For an axis with 0 set in this parameter, the deceleration function
based on acceleration is disabled. If 0 is set for all axes, the
deceleration function based on acceleration is not performed.
In circular interpolation, however, the deceleration function based on
feedrate control using acceleration in circular interpolation (parameter
No. 1735) is enabled.
1738
Minimum allowable feedrate for the deceleration function based on
acceleration in AI contour control
[Input type] Parameter input
[Data type] Real path
[Unit of data] mm/min, inch/min, degree/min (machine unit)
[Minimum unit of data] Depend on the increment system of the reference axis
[Valid data range] Refer to the standard parameter setting table (C)
(When the increment system is IS-B, 0.0 to +240000.0)
With the deceleration function based on acceleration in AI contour
control, a feedrate most suitable for a desired figure is automatically
calculated.
Depending on the figure, however, the calculated feedrate may
become too low.
In such a case, the feedrate is prevented from decreasing below the
value specified in this parameter.
If overriding using the deceleration function based on cutting load is
enabled, a feedrate lower than the minimum allowable feedrate may
be used.
