To continuously change the running frequency from the programmable controller
After the frequency setting complete (for example, X1021) turns ON, check that the reply code from the remote register is
H0000, then change the setting data (for example, W100) continuously.
Program example for writing data to EEPROM
Modify the following commands of the programming example on
Frequency setting command Y1021 Y1022
Frequency setting completion X1021 X1022

frequency
For EEPROM, write is made only once when Y1022 is switched on.
If the set data is changed with Y1022 on, it is not reflected on the inverter.
