14.3.4 Communication Mapping Register Address Distribution

Frequency converter parameter address

Frequency converter parameter registers correspond to the function codes one-
to-one. Reading and writing of related function codes can be achieved through
reading and writing of the contents in frequency converter parameter registers
via Modbus communication. The characteristics and scope of reading and writ-
ing function codes are in compliance with the frequency converter function code
description. The address of a frequency converter parameter register is com-
posed of a higher byte representing the function code group and a lower byte
representing the index in the group. The groups are mapped as follows:
Address
0x00
high byte
Group b0
Address
0x35
high byte
Group E5
Tab. 14-22: Frequency converter parameter registers
Parameters of the monitoring group (Group d0) are always write-pro-
tected.
Examples:
To read out the module temperature (d0.20) of EFC x610 frequency converter,
use register address 0x1014 (0x10 = Group d0, index 0x14 = 20).
To set V/f curve mode (C2.00) of EFC x610 frequency converter, use register ad-
dress 0x2200 (0x22 = Group C2, index 0).
Access to a non-existing function code will be acknowledged with exception
code 3 (see chapter 14.3.3 "Modbus Function and Message Format" on page
274).
