Parameter
1732
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 - +240000.0)
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.
