Replacing PLSR/DPLSR instruction to DRVI/DDRVI instruction

The PLSR/DPLSR (pulse output with acceleration and deceleration control) instruction of FX3 can be replaced to the DRVI/

DDRVI instruction.

The PLSR/DPLSR instruction can set the duration of time for acceleration and deceleration. Setting the duration of time for

acceleration or deceleration before executing the DRVI/DDRVI instruction enables the DRVI/DDRVI instruction to substitute

the PLSR/DPLSR instruction.
