(5) Isolating PLC option output when the inverter is tripped by LV (Low Voltage)
As described in page 7-7, (6) Terminal output, the method of isolating PLC output when the inverter is
tripped by LV (Low Voltage) is described below with an exemplary program.
▶ Common area of inverter
Referring to the parameters (exclusively for monitoring) of inverter common area in the “App. 4-4, page 4,
Appendix,” the addresses of the common area of the inverter level type trip information are as follows.
