• When the parameter "interpolation speed
designation method" performs a linear
interpolation in setting a "composite
speed", the axis movement amount for
each positioning data exceeds
30
1073741824(2
).
• The positioning address is
–360.00000 or less or 360.00000 or more
using INC instruction, where the control
unit is set to "degree" and software stroke
limit upper limit is not equal to the
software stroke limit lower limit.
When an arc is interpolated by the
designation of the center point, a difference
between a radius of start point-center point
and a radius of end point-center point
exceeds the parameter "Circular
interpolation error allowable limit".
