2) To continuously change the running frequency from the PLC
When the frequency (speed) setting completion (example: X100D) switches on, make sure that the reply
code in the remote register is 0000H and change the set data (example: W101) continuously.
3) Program example for writing data to EEPROM
Modify the above program as follows:
Frequency setting command Y100D → Y100E
Frequency setting completion X100D → X100E

For EEPROM, write is made only once when Y100E is switched on.

If the set data is changed with Y100E on, it is not reflected on the inverter.
