Programming example for setting the operation commands
The following program gives a forward rotation command and middle-speed operation command to
the station 1 inverter
These signals are initial values. Input signals can be changed using Pr. 180 to Pr. 189 (input terminal
function selection).
Note that some of the signals do not receive a command from the programmable controller
depending on the setting.
Programming example for monitoring the output frequency
The following explains a program to read monitor functions of the inverter.
●
The following program reads the output frequency of the station 1 inverter to output to D1.
●
Output frequency read code: H0001 (hexadecimal)
(For the monitor codes, refer to page 5-344.)
Example: The output frequency of 60 Hz is indicated as "H1770 (6000)".

Check the data link status of the station 1.
Set the monitor code (H01) of output frequency in
RWw0.
Turn ON the monitor command (RY0C).
Read the output frequency (RWr0) to output to D1
when the monitoring (RX0C) turns ON.
