These signals are initial values. You can change input signals 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.
(Refer to the Instruction Manual (Detailed) of the inverter for the details.)
 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 station 1 inverter to D1.
Output frequency read code: H0001 (hexadecimal)
For the monitor codes, refer to
(Example) The output frequency of 60 Hz is indicated as H1770 (6000).
