Modbus Holding Registers
The following tables list the holding registers for the inverter interface to the network. The table legend
is given below.
• Function Code Function Code - - - - The inverter's reference code for the parameter or function (same as inverter keypad
Function Code Function Code
display)
• Name Name Name - - - - The standard functional name of the parameter or function for the inverter Name
• R/W R/W - - - - The read-only(R) or read-write access(R/W) permitted to the data in the inverter R/W R/W
• Description Description - - - - How the parameter or setting works (same as Chapter 3 description).

• Reg. Reg. - - - - The network

address.
• Range Range - - - - The numerical range for the network value that is sent and/or received Range Range
TIP: TIP: TIP: TIP: The network values are binary integers. Since these values cannot have an embedded decimal point,
for many parameters it represents the actual value (in engineering units) multiplied by a factor of 10 or
100. Network communications must use the listed range for network data. The inverter automatically
divides received values by the appropriate factor in order to establish the decimal point for internal use.
Likewise, the network host computer must apply the same factor when it needs to work in engineering
units. However, when sending data to the inverter, the network host computer must scale values to the
integer range listed for network communications.
• Resolution Resolution Resolution Resolution - - - - This is the quantity represented by the LSB of the network value, in engineering units.
When the network data range is greater than the inverter's internal data range, this 1-bit resolution
will be fractional.
