160 ACH550-UH User’s Manual
Serial Communication – EFB
The ACH550 supports the following Modbus function codes for 3xxxx registers:
4xxxx Register Mapping. The drive maps its parameters and other data to the
4xxxx holding registers as follows:
• 40001…40099 map to drive control and actual values. These registers are
described in the table below.
• 40101…49999 map to drive parameters 0101…9999. Register addresses that do
not correspond to drive parameters are invalid. If there is an attempt to read or
write outside the parameter addresses, the Modbus interface returns an
exception code to the controller.
The following table summarizes the 4xxxx drive control registers 40001…40099 (for
4xxxx registers above 40099, see the drive parameter list, e.g. 40102 is parameter
0102):
30002 AI2 This register shall report the level of Analog Input 2 (0…100%).
