Programming example for setting the running frequency
The following program changes the running frequency of the station 1 inverter to 50.00 Hz.
●
Set frequency: K5000 (decimal)
●
The reply code (RWr0) to the instruction code execution is set in D2.
(Refer to page 5-756 for the reply code (RWr0).)
To the EEPROM, a writing is performed only once after the command Y1022 turns ON.
If the set data is changed at the command Y1022 ON, the change is not applied to the inverter.

NOTES To change the running frequency continuously using a programmable controller, check that the
frequency setting complete (for example, X1021) turns ON, and the reply code from the intelligent
register is H0000. Then change the setting data (for example, W100) continuously.
To write the running frequency to the EEPROM, change the following points in the program
shown in fig. 5-380:
●
Frequency setting command: Y1021 Y1022
●
Frequency setting completion: X1021 X1022

Check the data link status of the station 1.
Read the reply code (RWr0) to output to D2 when the
frequency setting completion (RX21) turns ON.
Write the set frequency to RWw0.
