Minimum allowable feedrate for the deceleration function based on
acceleration in circular interpolation
[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 circular
interpolation, an optimum feedrate is automatically calculated so that
acceleration produced by changing the move direction in circular
interpolation does not exceed the maximum allowable acceleration
rate specified in parameter No. 1735.
If the radius of an arc is very small, a calculated feedrate may become
too low.
In such a case, the feedrate is prevented from decreasing below the
value specified in this parameter.
NOTE
During involute interpolation, the minimum
allowable feedrate of "clamping of acceleration
near a basic circle" in involute interpolation
automatic feedrate control is used.
1735
Maximum allowable acceleration rate for the deceleration function based on
acceleration in circular interpolation 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 for the deceleration
function based on acceleration in circular interpolation.
Feedrate is controlled so that acceleration produced by changing the
move direction in circular interpolation does not exceed the value
specified in this parameter.
For an axis with 0 set in this parameter, the deceleration function
based on acceleration is disabled.
If a different value is set in this parameter for each axis, a feedrate is
determined from the smaller of the acceleration rates specified for the
two circular axes.
