4. After you finish setting up the parameter table, recompile the programs and download them to
the PLC program, and then reboot the drive to make CMC-PN01 receive the updated
parameter settings.
5. When CMC-PN01 is connected to the PLC program successfully, you can test the reading or
writing of the set parameter by using the Watch Table. The Watch Table shows as the figure
below.
Follow the four steps as shown below to verify if the settings for the parameter table are
workable and if reading or writing the drive parameters is successful (can be used with the
keypad to verify).
※ Note: The figure above shows that %IW312 is the status value returned when the
parameter table reads or writes the parameters. Low byte is the status value of reading,
whereas high byte is the status value of writing. Take the figure above as an example, if the
status value is 0x8183, the values of 1, 2, and 8 in the parameter table are successfully
read and the values of 1 and 8 are successfully written. Thus, as can be seen, the success
or failure of the parameter reading/writing depends on this status value.
※ %IW312 = I/O start address + 56 (the I/O start address in this example is 256).
※ If you do not need to write the parameters synchronously (with time constraint), it is
suggested to write the parameters asynchronously (without time constraint).
