5.4 How to Access Parameters
5.4.1 Parameter Handling
The PNU (Parameter Number) is translated from the register address contained in the Modbus read or write message. The parameter number is translated to
Modbus register address as (10 x parameter number -1)
DECIMAL
.
5.4.2 Storage of Data
The Coil 65 decimal determines whether data written to the frequency converter are stored in EEPROM and RAM (coil 65 = 1) or only in RAM (coil 65 = 0).
5.4.3 IND
The array index is set in Holding Register 9 and used when accessing array parameters.
5.4.4 Text Blocks
Parameters stored as text strings are accessed in the same way as the other parameters. The maximum text block size is 20 characters. If a read request for a
parameters is for more characters than the parameter stores, the response is truncated. If the read request for a parameter is for fewer characters than the
parameter stores, the response is space filled.
5.4.5 Conversion Factor
The different attributes for each parameter can be seen in the section on factory settings. Since a parameter value can only be transferred as a whole number,
a conversion factor must be used to transfer decimals. Please refer to the section
Conversion Index
.
5.4.6 Parameter Values
Standard Data Type
Standard data types are int16, int32, uint8, uint16 and uint32. They are stored as 4x registers (40001 - 4FFFF). The parameters are read using function 03
HEX
“Read
Holding Registers”. Parameters are writtein using the function 6
HEX
“Preset Single Register” for 1 register (16 bits), and the function 10
HEX
“Preset Multiple Registers”
for 2 registers (32 bits). Readable sizes range from 1 register (16 bits) up to 10 registers (20 characters).
Non Standard Data Types
Non standard data types are text strings and are stored as 4x registers (40001 - 4FFFF). The parameters are read using function 03
HEX
“Read Holding Registers”
and written using function 10
HEX
“Preset Multiple Registers”. Readable sizes range from 1 register (2 characters) up to 10 registers (20 characters).
