Modbus Status and Fault Code Registers
The following table provides information about the registers that are used to report
status and fault codes. Each of these registers provides information about a group of
status codes or faults. For more information on the specific faults that can be reported
for each of the fault registers, see the troubleshooting information for the inverter.
For more information about the status codes, see Table 6‑20 on page 6‑27 and
Table 6‑21 on page 6‑27.
