Set a value in " Da.7 Command speed" so that the speed of each axis does not
exceed the " Pr.7 Speed limit value". (The speed limit does not function for the
speed calculated by the AD75 during interpolation control.)

(INC right arc, INC left arc)
Operation chart
In the increment system, 2-axis circular interpolation control with center point
designation, addresses established by a machine zero point return on a 2-axis
coordinate plane are used. Positioning is carried out from the current stop position
(start point address) to a position at the end of the movement amount set in
" Da.5 Positioning address/movement amount", in an arc path having as its
center the address (arc address) of the center point set in " Da.6 Arc address".
