*7. Variable speed pulse output instruction is used to perform this operation.
Operations with acceleration/deceleration are supported in the FX
3U/FX3UC PLC Ver. 2.20 or later and FX3G
PLC.
*8. Operates with acceleration/deceleration.
*9. When interpolation instructions are consecutively set in the program, it will immediately shift to the
next operation. (continuous pass operation).
*10. When the interpolation operation is continuously set in the table operation, it will immediately shift to
the next operation. (Continuation pass function)
