Register Mapping - ABB ACS355 series User Manual



Register mapping

The drive parameters, Control/Status word, references and actual values are mapped
to the area 4xxxx so that:
• 40001...40099 are reserved for drive control/status, reference and actual values.
• 40101...49999 are reserved for drive parameters 0101...9999 (eg, 40102 is
parameter 0102). In this mapping, the thousands and hundreds correspond to the
group number, while the tens and ones correspond to the parameter number
within a group.
The register addresses that do not correspond with drive parameters are invalid.
If there is an attempt to read or write invalid addresses, the Modbus interface returns
an exception code to the controller. See
The following table gives information on the contents of the Modbus addresses
40001...40012 and 40031...40034.
