Embedded fieldbus
attempt to read or write outside the parameter addresses, the Modbus interface
returns an exception code to the controller.
• Register addressing is done as follows:
– For drive parameters use: 400000 + 256 * parameter group + parameter index.
For example: parameter 22.80 would be mapped to register 400000 + 256 *
22 + 80 = 405712.
– For bypass parameters use: 400000 + 256 * (parameter group + 128) +
parameter index.
For example: bypass parameter 01.11 would be mapped to register 400000 +
256 * (1 + 128) + 11 = 433035.
The following table summarizes the 4xxxxx drive control registers 400001…400099
(for 4xxxxx registers above 400099, see the drive parameter list, e.g. 400258 is
parameter 0102):

400001 ABB DRIVES
PROFILE CONTROL
WORD
R/W Maps directly to the profile’s Control Word. Supported
only if bypass parameter 5825 = 0 or 2 (ABB drive
profile). Bypass parameter 5318 holds a copy in hex
format.
400002 Reference 1 R/W Range = 0...+20000 (scaled to +maximum reference),
or -20000...0 (scaled to -maximum reference). Where:
maximum reference is drive parameter 46.01, Speed
scaling if control mode is vector or parameter 46.02,
Frequency scaling if control mode is scalar.
400003 Reference 2 R/W Range = 0...+10000 (scaled to +maximum reference),
or -10000...0 (scaled to -maximum reference). Where:
maximum reference is drive parameter 46.01, Speed
scaling if control mode is vector or parameter 46.02,
Frequency scaling if control mode is scalar.
400004 ABB DRIVES
PROFILE STATUS
WORD
R Maps directly to the profile‘
S STATUS WORD.
Supported only if bypass parameter 5825 = 0 or 2 (ABB
bypass profile). Bypass parameter 5819 holds a copy in
hex format.
400005
1
Actual 1.
(select using drive
parameter 58.28,
EFB act1 type)
R By default, stores a copy of speed or frequency. Use
drive parameter 58.28 to select a different value.
400006
2
Actual 2.
(select using drive
parameter 58.29,
EFB act2 type)
R By default, stores nothing. Use drive parameter 58.29
to select a value.
400007 Actual 3.
(select using bypass
parameter 58107)
R By default, stores nothing. Use bypass parameter 5312
to select an actual value for this register.
400008 Actual 4.
(select using bypass
parameter 58108)
R By default, stores nothing. Use bypass parameter 5313
to select an actual value for this register.
400009 Actual 5.
(select using bypass
parameter 58109)
R By default, stores nothing. Use bypass parameter 5314
to select an actual value for this register.
400010 Actual 6.
(select using bypass
parameter 58110)
R By default, stores nothing. Use bypass parameter 5315
to select an actual value for this register.
