)
during linear interpolation with “synthetic
speed” specified as an “interpolation speed
designation method” parameter.
The positioning address of the INC command
is equal to or smaller than -360.00000 or
equal to or larger than 360.00000 with the
“degree” unit setting and inequality between
the upper and the lower software stroke
limits.

deviation
The difference between the radius from the
start point to the center point and the radius
from the end point to the center point exceeds
the “allowable range of arc interpolation error”
during arc interpolation with center point
designation.
At start: The arc interpolation control with
center point designation is not
executed.
During operation: Immediate stop
