38 Start-up
Mode 0 Used when access to parameter indexes
greater than 99 is not needed.
Allows 5-digit addressing
1)
used by legacy
Modbus masters.
16-bit access:
1)
Register address
2)
= 100 * parameter
group + parameter index (16-bit values,
groups 1...199, indexes 1...99).
32-bit access:
Register address = 20000 + 200 *
parameter group + 2 * parameter index (32-
bit values, groups 1...199, indexes 1...99).
Example, 5101 (0x13ED) is group
51
index.
1) 6-digit register addressing (400001) is
used instead of 5-digit register addressing
(40001) to describe register map.
2) Register address = Register a
40000 (0) if holding register area indication
should be used.
For more information, see
Register
addressing on page 70 .
Mode 1 16-bit access:
Register address = 256 * parameter group
+ parameter index (16-bit values, groups
1...255, indexes 1...255).
Example, 13057 (0x3301) is group
51
index 1.
Mode 2 32-bit access:
Register address = 512 * parameter group
+ 2 * parameter index (32-bit values,
groups 1...127, indexes 1...255).
Example: 26114 (0x6602) is group
51 index
1.
Used when 32-bit parameter values are
needed and there is no need to access
groups 128 or higher.
Mode 3 32-bit access:
Register address = 256 * parameter group
+ 2 * parameter index (32-bit values,
groups 1...255, indexes 1...127).
Example: 13058 (0x3302) is group
51
index 1.
Used when 32-bit parameter values are
needed and there is no need to access
parameter index 128 or higher.
