*1. Shaded columns are invalid in interpolation operation.
*2. In interpolation operation, the system performs trapezoidal acceleration/deceleration even if
approximate S-shaped acceleration/deceleration is selected.
*3. For cautions on setting the pulse rate and feed rate in interpolation operation, refer to the following.
Note
• The radius is specified as r. When r is a positive value, the small circle (a) path is selected and when it is
negative, the big circle (b) path is selected.
• Pulse rate and feed rate
During the circular interpolation operation, the radius value is kept constant and pulses are allocated to the
X and Y axes. If the ratio of the pulse rate to the feed rate differs between the X-axis and Y-axis, the circle
becomes deformed. Set the interpolation gear ratio selection function in the X- axis, Y-axis when the ratio
differs between the X-axis and the Y-axis if the version is Ver.1.20 or later.
• Use the center coordinate specification in a perfect circle operation.
• During continuous pass operation
If the circular path is too short and the travel time from the start point to the target point is shorter than the
interpolation time constant, the operation temporarily stops, and shifts to the next interpolation operation.
• When interpolation operations are consecutively repeated in a table operation, the 20SSC-H provides
continuous pass operation.
2. Operation information
Set a circular interpolation operation ("radius, CW direction" or "radius, CCW direction") and an absolute/
relative address in the operation information.
