Lenze i55 Series User Manual

Variable mapping
•
Via 0x232B:001 ... 0x232B:024 (P530.01 ... 24), 24 registers can be mapped to parameters
of the inverter.
Format: 0xiiiiss00 (iiii = index hexadecimal, ss = subindex hexadecimal)
•
The display of the internal Modbus register numbers in 0x232C:001 ... 0x232C:024
(P531.01 ... 24) is generated automacally. Since 32-bit parameters require two registers,
there is no 1:1 assignment.
•
For the mappable registers, a CRC (Cyclic Redundancy Check) is executed. The checksum
determined is displayed in 0x232D (P532.00). The user can read this "validaon code" and
use it for comparison in the Modbus master. In this way it can be checked whether the
inverter currently queried is congured correctly for the respecve applicaon.

Display of the internal Modbus register number starng from which the
parameter mapped in 0x232B:001 ... 0x232B:024 (P530.01 ... 24) is
stored.
•
For the rst parameter mapped, always 2500.
•
From the second parameter mapped, 2500 + oset. The oset results
from the data types of the previously mapped parameters.

9.5.9 LED status displays
Informaon 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.
