Parameter
Setting the running frequency
The following program example changes the running frequency of station 1 inverter to 50.00 Hz.
● Set frequency: K5000 decimal
The reply code at the time of instruction code execution is set to D2.
(For information about the reply code (RWr2) refer to page 6-360.)

NOTES To continuously change the running frequency from the programmable controller
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.
Program example for writing data to E²PROM
Modify the program in fig. 6-183 as follows:
● Frequency setting command Y100D
● Frequency setting completion X100D
Inverter running
For E²PROM, 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.
