Allowable circular interpolation error width
(a) With the circular interpolation control using the center point designation, the arc
path calculated with the start point address and center point address and the end
point address may deviate.
(b) With the allowable circular interpolation error width, the allowable error range of
the calculated arc path and end point address can be set. If the error of the
calculated arc path and end point address are within the set range, circular
interpolation will be carried out to the set end point address while compensating
the error with spiral interpolation.
(c) The allowable circular interpolation error width is set in the following axis detailed
parameter.
• If axis 1 is the reference axis, set in the axis 1 detailed parameter.
• If axis 2 is the reference axis, set in the axis 2 detailed parameter.
• If axis 3 is the reference axis, set in the axis 3 detailed parameter.
• If axis 4 is the reference axis, set in the axis 4 detailed parameter.

External command function selection
Select a function with which the external command signal should be associated.
(1) When the external positioning start is set
• The external command signal input is used to start positioning operation.
(2) When the external speed change request is set
• The external command signal input is used to change the speed in the current
positioning operation.
• Set a new speed value to the "new speed value" of axis control data for external
speed change.
(3) Speed-position/position-speed switching request
• The external command signal input is used to switch from the speed control to
the position control/from the position control to the speed control during the
speed-position switching control mode/position-speed switching control mode.
• To enable the speed-position switching control, set 1 to the speed-position
switching enable flag (1528, 1628, 1728, and 1828) of the buffer memory.
• To enable the speed-position switching control, set 1 to the position-speed
switching enable flag (1532, 1632, 1732, and 1832) of the buffer memory.
(4) When the skip request is set
• The external command signal input is used to skip the current positioning
operation.
POINT
To enable the external command signal, set 1 to the "external command enable"
(1505, 1605, 1705, and 1805) of the buffer memory.
