Chapter 10 ALARM CODE LIST
The information on alarms that have occurred in the inverter can be monitored through DeviceNet.
They are stored in the inverter's function codes M16 to M19 as listed in Table 10.1.
The communication dedicated function codes M16 to M19 store information on the current alarm code, most
recent alarm code, 2nd recent alarm code, and 3rd recent alarm code, respectively.
