Instructions
1
Inverter operation monitoring instruction [IVCK]
This instruction reads the operating status of an inverter and stores the read value in (d1) when an instruction
code set in the computer link operation of the inverter is specified.
IVCK

Example program
The following program reads the status (H7A) of the inverter (station number 0), stores the read value in M100 to
M107 of the programmable controller, and outputs it externally.
