• Start point radius > End point radius: As compared with the speed without error, the speed becomes slower
as end point address is reached.
• Start point radius < End point radius: As compared with the speed without error, the speed becomes faster
as end point address is reached.
(b) Restrictions
2-axis circular interpolation control cannot be set in the following cases.
• When "degree" is set in "[Pr.1] Unit setting"
• When the units set in "[Pr.1] Unit setting" are different for the reference axis and interpolation axis. ("mm"
and "inch" combinations are possible.)
• When "reference axis speed" is set in "[Pr.20] Interpolation speed designation method"
An error will occur and the positioning will not start in the following cases. The machine will immediately stop if
the error is detected during positioning control.
• When the radius exceeds "536870912 (=2
29
)". (The maximum radius for which circular interpolation
control is possible is "536870912 (=2
29
)"

An error "Outside radius range" (error code: 544) will occur at
positioning start.
• When the end point address is outside the range of -2147483648(-2
31
) to 2147483647(2
31
-1): The error
"End point setting error" (error code: 526) will occur.
• When the start point address is the same as the center point address

The error "Center point setting
error" (error code: 527) will occur.
• When the end point address is the same as the center point address

The error "Center point setting
error" (error code: 527) will occur.
• When the center point address is outside the range of -2147483648(-2
31
) to 2147483647(2
31
-1): The error
"Center point setting error" (error code: 527) will occur.
