Linear Interpolation Operation (Interrupt Stop)

1. Operation
Y axis
1) Set the operation speed 1 for the X-axis and the target address 1 (maximum travel distance) for the X/Y-axis.
2) Select the linear interpolation operation (interrupt stop) from the X-axis and Y-axis operation patterns and
turn ON the START command for the X-axis. The linear interpolation operation (interrupt stop) shown
above will operate at the specified vector speed (X-axis operation speed 1). (The positioning completion
signal is turned OFF.)
The START command of the Y-axis is ignored.
3) At interrupt input (INT0) ON before the XY coordinate in target address 1, the work piece decelerates to
stop, and the operation ends, turning the positioning completion signal ON.
When the interrupt input (INT0) does not turn ON before the XY coordinate in target address 1, the work
piece moves to the target address 1, and the operation ends, turning the positioning completion signal ON.
Note
• When interpolation operations are consecutively repeated in a table operation, the 20SSC-H provides
continuous pass operation.
2. Operation speed
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.
