5. The parameters modified by the instruction can only be modified while the PLC is running. The last written
parameter is not saved when the power turns OFF. The table that you edit in ISPSoft and download to the PLC is
processed as the default position planning table when the power is ON.
6. This instruction does NOT modify the acceleration or deceleration time. If you need to modify the time for
acceleration or deceleration, you can set SM585 flag to ON, and the system refers to the acceleration and
deceleration time set in SR to change the acceleration time in single-axis point-to-point motion and single-axis multi-
segment motion or the deceleration time in single-axis point-to-point motion. Re-execute this instruction to actualize
this modification. This function is available for PLC with FW V1.06.00.
Example 1: Change the parameters of Axis 3 of Number 5 during execution in Single-axis point-to-point motion.
1) Use DMOV instruction to define new target position and target speed.
2) Use MOV instruction to define the start/end frequency in SR503, acceleration time in SR504 and deceleration
time in SR505 for Axis 3. After that the relative parameters in single-axis point-to-point motion are updated.
3) Set the flag SM585 to ON.
4) Re-execute DTPWS instruciton to actualize the modification.

5) After that, SM585 switches to OFF automatically.
Example 2: Change the parameters of Axis 3 of Number 2 during execution in Single-axis multi-segment motion.
1) Use DMOV instruction to define new target position and target speed.
2) Use MOV instruction to define the acceleration time in SR504. After that the relative parameters in single-axis
multi-segment motion are updated.
3) Set the flag SM585 to ON.
4) Re-execute DTPWS instruciton to actualize the modification.
5) After that, SM585 switches to OFF automatically.
