Avoid write during RUN to a circuit block including the following
instructions during execution. If write during RUN is executed to such a
circuit block, the PLC decelerates and stops pulse output.

Avoid write during RUN to a circuit block including the following instruction
during execution. If write during RUN is executed to such a circuit block,
the PLC immediately stops pulse output.
