• 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.
3. Speed information
The actual operation speed (vector speed) is "X-axis operation speed 1 x X-axis override setting."
The operation speed 1 for the X-axis can be changed using the operation speed change function except
under the following conditions.
• During deceleration operation
• When the speed change disable during operation signal is ON.
4. Position (address) information
The absolute/relative address can be specified in the operation information.
With the specified absolute address: Specifies a target address (position) using address 0 as the base.
With the specified relative address:
5. Circle information (radius)
Set the radius of a circle with by r.
With specified positive (+) value: Operates the small circle (a) path.
With specified negative (-) value: Operates the big circle (b) path.
