(3) Examples for writing and reading to/from function codes
Normal writing and reading
This example shows communication data for writing to function code F03 (=0403h) to change the data from
factory default 60.0 Hz (=0258h) to 300.0 Hz (=0BB8h) and then reading from F03. (The following data is
expressed in hexadecimal.)
Select the inverter's function code F03.
Write: 00 00 00 00 03 04 00 00
Read: 28 10 00 00 00 00 00 00
Input data to F03.
Write: 00 00 00 00 03 04 B8 0B
Read: 28 10 00 00 00 00 00 00
Write data into F03.
Write: 00 10 00 00 03 04 B8 0B
Read: 28 10 00 00 03 04 B8 0B
Read from F03.
Write: 00 08 00 00 03 04 00 00
Read: 28 10 00 00 03 04 B8 0B
Reading/writing error
This example shows communication data that returns an error code since writing and reading to/from
nonexistent function code F99 (=0463h) is attempted.
Select the inverter's function code F99.
Write: 00 00 00 00 63 04 00 00
Read: 28 10 00 00 00 00 00 00
Write data into F99.
Write: 00 10 00 00 63 04 00 00
Read: 28 50 00 00 63 04 02 1F
Read from F99.
Write: 00 08 00 00 63 04 00 00
Read: 28 50 00 00 63 04 21 1F
