Register Mapping
The drive parameters are mapped to the 4xxxx area so that:
• 40001 – 40099 are reserved for drive control registers
• 40101 – 40199 is reserved for the actual values (parameter group 1)
• 40201 – 40299 is reserved for parameter group 2
• 40301 – 40399 is reserved for fault and alarm information
•… other parameter groups
• 49901 – 49999 is reserved for the start-up data
Register addresses 4GGPP are shown in Table 19. In this table GG is the group number, and PP is
the parameter number within the group.
Table 19 Parameter mapping.
The register addresses between the groups are invalid. No reads or writes are allowed for these
addresses. If there is an attempt to read or write outside the parameter addresses, the Modbus
interface will return an exception code to the controller.
