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 24. In this table GG is the group number, and PP is
the parameter number within the group.
