5.3.5.8 [System Settings] status details
In the [System Settings] status, there are functions for setting date/time, program upgrade, and
waveform acquisition. In which, program upgrade can be performed via the operator to upgrade the
main control and IO board program; the waveform acquisition function can be enabled to achieve
waveform acquisition (the acquisition channel can be configured), automatically stored to the SD
card.

5.4 Fault display
When the inverter has a fault, the fault code and name are displayed in the operator LCD screen. For
the fault code and name, see Table 5.5.
