Fieldbus control 341
The following table summarizes the input registers:
The drive supports the following Modbus function codes for 3xxxx registers:
4xxxx Register Mapping. The drive maps its parameters and other data to the 4xxxx
holding registers as follows:
• 40001…40099 map to drive control and actual values. These registers are
described in the table below.
• 40101…49999 map to drive parameters 0101…9999. Register addresses that do
not correspond to drive parameters are invalid. If there is an attempt to read or
write outside the parameter addresses, the Modbus interface returns an exception
code to the controller.
The following table summarizes the 4xxxx drive control registers 40001…40099 (for
4xxxx registers above 40099, see the drive parameter list, for example, 40102 is
parameter 0102):

Modbus Register Access Remarks
40001 R/W Maps directly to the profile. Supported only if 5305 =
0 or 2 (ABB Drives profile). Parameter 5319 holds a
copy in hex format.
40002 Reference 1 R/W Range = 0…+20000 (scaled to 0…1105 REF1 MAX,
or
-20000…0 (scaled to 1105 REF1 MAX…0).
40003 Reference 2 R/W Range = 0…+10000 (scaled to 0…1108 REF2 MAX,
or
-10000…0 (scaled to 1108 REF2 MAX…0).
40004 R Maps directly to the profile. Supported only if 5305 =
0 or 2 (ABB Drives profile). Parameter 5320 holds a
copy in hex format.
40005 Actual 1
(select using 5310)
R By default, stores a copy of 0103 OUTPUT FREQ.
Use parameter 5310 to select a different actual value
for this register.
40006 Actual 2
(select using 5311)
R By default, stores a copy of 0104 CURRENT. Use
parameter 5311 to select a different actual value for
this register.
40007 Actual 3
(select using 5312)
R By default, stores nothing. Use parameter 5312 to
select an actual value for this register.
40008 Actual 4
(select by 5313)
R By default, stores nothing. Use parameter 5313 to
select an actual value for this register.
40009 Actual 5
(select using 5314)
R By default, stores nothing. Use parameter 5314 to
select an actual value for this register.
