PROGRAMMING EXAMPLES
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 0000H and change the set data (example: RWw5) continuously.
3)Program example for writing data to E2PROM Modify the above program as follows:
Change the frequency setting command from RY2D to RY2E.
Frequency setting completion RX2D → RX2E

Note: 1. For E2PROM, 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.
