■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 start will not be possible in the following cases. The machine will immediately stop if the
error is detected during positioning control.
• When the radius exceeds "536870912 (= 2
possible is "536870912 (= 2
• When the start point address is the same as the center point address: The error "Center point setting error" (error code:
1A2DH) will occur.
• When the end point address is the same as the center point address: The error "Center point setting error" (error code:
1A2DH) will occur.
• When the center point address is outside the range of -2147483648 (-2
setting error" (error code: 1A2DH) will occur.
■Setting positioning data
When using 2-axis circular interpolation control with center point designation (ABS circular right, ABS circular left), set the
following positioning data.
: Always set, : Set as required, : Setting not required
Setting item
[Da.1] Operation pattern
[Da.2] Control method
[Da.3] Acceleration time No.
[Da.4] Deceleration time No.
[Da.6] Positioning address/movement amount

Refer to the following for information on the setting details.
Page 416 Positioning Data
Set a value in "[Da.8] Command speed" so that the speed of each axis does not exceed the "[Pr.8] Speed limit
value". (The speed limit does not function for the speed calculated by the Simple Motion module during
interpolation control.)
