[Data type] Byte
[Unit of data] %
[Valid data range] 1 to 100
Set the override function based on a curvature radius. The curvature
radiuses Rlmt1, Rlmt2, Rlmt3, Rlmt4, and Rlmt5, and the override values
OVR2, OVR3, OVR4, and OVR5 must have the relationships indicated
below. If the following relationships are not satisfied, this function does
not operates:
Rlmt1 > Rlmt2 > Rlmt3 > Rlmt4 > Rlmt5 > 0
100% > OVR2 > OVR3 > OVR4 > OVR5 > 0%
No. Message Description
241 END POINT, I, J, K, AND
R ARE MISSING
The end point of an involute curve, I,
J, or K is not specified.
242 SPECIFICATION ERROR
(INVOLUTE)
An illegal value is specified for invo-
lute interpolation.
(1)The specified start point or end point
is located inside the base circle.
(2)Zero is specified for I, J, K, or R.
(3)The start point or end point is located
more than 100 turns from the beginning
of the involute curve.
243 END POINT NOT ON IN-
VOLUTE CURVE
The end point is not on the involute
curve that passes through the start
