Embedded fieldbus
Except where restricted by the system, all parameters are available for both reading
and writing. The parameter writes are verified for the correct value, and for a valid
register addresses.
Note:
Parameter writes through standard Modbus are always volatile i.e. modified
values are not automatically stored to permanent memory. Use bypass parameter
1615 PARAM. SAVE to save all altered values.
The system supports the following Modbus function codes for 4xxxxx registers:
Actual values
The contents of the register addresses 400005…400012 are
ACTUAL
VALUES
and
are:
• 400005 and 400006 are specified using drive parameters 58.28…58.29
• 400007…400012 are specified using bypass parameters 58107…58112.
• Read-only values containing information on the operation of the drive.
• 16-bit words containing a sign bit and a 15-bit integer.
• When negative values, written as the two’s complement of the corresponding
positive value.
• Scaled as described earlier in
Exception codes
Exception codes are serial communication responses from the drive. The drive
supports the standard Modbus exception codes defined below.
