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.

Replacing ZRN/DZRN instruction to DSZR/DDSZR instruction

The ZRN/DZRN (OPR) instruction of FX3 can be replaced to the DSZR/DDSZR instruction.
With the OPR parameters as below, the operation of the DSZR/DDSZR instruction is the same as that of the ZRN/DZRN
instruction. Other parameters can be set as desired. For each parameter, refer to Page 41 POSITIONING PARAMETER.
