2) To continuously change the running frequency from PLC
When the frequency setting completion (example: RX2D) switches on, make sure that the reply code in the remote
register is 0000
H
and change the set data (example: RWw
5
) continuously.
3) Program example for writing data to E

PROM
Modify the above program as follows:
Change the frequency setting command from RY2D to RY2E.
RY2D
RW

PROM, write is made only once when RY2E is switched on.
2. If the set data is changed with RY2E on, it is not returned on the inverter.
