504
Outside linear
movement amount
range
• 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
1073741824(2
30
).
• 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.
At start: The system will not operate.
During operation:
The system stops
immediately.

Large arc error
deviation
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".
At start: The circular interpolation
control by center point
designation is not executed.
During operation :
The system will stop
immediately.
