■Restrictions
In the following cases, the 2-axis circular interpolation control cannot be set.
• When "2: degree" is set in [Pr.1] Unit setting
• When the units set in [Pr.1] Unit setting are different between the reference axis and interpolation axis (The combination of
"0: mm" and "1: inch" is possible.)
• When "1: Reference axis speed" is set in [Pr.20] Interpolation speed specification method
In the following case, an error occurs and the positioning will not start. During positioning control, the operation stops
immediately at the detection of the error.

■Positioning data to be set
To use the 2-axis circular interpolation control with center point specified (ABS circular right, ABS circular left), set the
following positioning data.
: Always set
: Set as required
: Setting not required

[Da.1] Operation pattern
[Da.2] Control method
[Da.3] Acceleration time No.
[Da.4] Deceleration time No.

[Da.6] Positioning address/movement amount
[Da.7] Arc address
[Da.8] Command speed
[Da.9] Dwell time

For details on the settings, refer to the following.
Page 410 Positioning Data
Set a value in [Da.8] Command speed so that the speed of each axis does not exceed the value in [Pr.8]
Speed limit value. (The speed limit does not function for the speed calculated using the positioning module.)
