Information about the Modbus status can be obtained quickly via the "MOD-RUN" and "MOD-
ERR" LED displays on the front of the inverter.
The meaning can be seen from the tables below.
Inverter not active on the Modbus bus (yet)

• Format: 0xiiiiss00 (iiii = index, ss = subindex)
Display of the internal Modbus register number starting from which the
parameter mapped in 0x232B:001 ... 0x232B:024 (P530.01 ... 24)
stored.
• For the first parameter mapped, always 2500.
• From the second parameter mapped, 2500 + offset. The offset results
from the data types of the previously mapped parameters.
