6.INTERPOLATION FUNCTION B-63783EN-1/01
- 578 -
6630 Lower override limit of automatic velocity control during involute
interpolation
[Input type] Parameter input
[Data type] Integer
[Unit of data] %
[Valid data range] 0 - 100
When the override function is used in the cutter compensation mode for
involute interpolation automatic velocity control, the feedrate of the too
center may be reduced to an extremely low level near the base circle in
the case of internal offset. To void this, set a lower override limit in thi
parameter.
Thus, the feedrate is clamped so that the feedrate is not reduced below
the specified feedrate overridden by the lower limit value set in this
parameter.
NOTE
When 0 or a value not within the specifiable range is set, involute
interpolation automatic velocity control (override in the cutter
compensation mode and acceleration/deceleration clamping
near a base circle) is disabled.
Alarm and message
Number Message Contents
PS0935 ILLEGAL FORMAT IN G02.2/G03.2 The end point of an involute curve on the currently selected
plane, or the center coordinate instruction I, J or K of the
corresponding basic circle, or basic circle radius R was not
specified.
PS0936 ILLEGAL COMMAND IN G02.2/G03.2 An illegal value was specified in the involute curve.
The coordinate instruction I, J or K of the basic circle on the
currently selected plane or the basic circle radius R is "0",
or the start and end points are not inside the basic circle.
PS0937 OVER TOLERANCE OF END POINT The end point is not positioned on the involute curve that
passes through the start point, and this error exceeds the
permissible error limit (parameter No. 2510).
