Example 2: Modify the parameter values (RAM and EEPROM are modified)
Modify keypad settings frequency value (the address of keypad set frequency is 4) which
can be achieved by setting PKW1 as 2; PKW2 as 4, modification value (50.00) is in PKW4.

Example for PZD:
Transmission of PZD area is achieved through inverter function code; please refer to
relevant INVT inverter user manual to know relevant function code.
Example 1: Read process data of inverter
Inverter parameter selects "8: Run frequency" as PZD3 to transmit which can be achieved
by setting Pd.14 as 8. This operation is mandatory until the parameter is instead of others.
