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.
