Low byte of parameter index: low byte of parameter index corresponds to low byte address of
inverter parameters.
4.4.1.3 PWE
PWE corresponding to parameters values are 2 words, which includes PWE1 and PWE2. When
master executes reading command, both PWE1 and PWE2 are 0. When master executes writing
command,PWE1 is 0, PWE2 is parameter value. When master operates successfully, PWE1 returns
to 0, PWE2 returns to actual parameter values. If master operates failed, PWE1 returns to 0, PWE2
returns to error code.
4.4.1.4 Examples of PKW
For example, master reads F111 value. The command value of reading parameter is 1,
parameter actual address is 0x010B. If parameter value is 10000=0x2710, and response is failed,
error code 0x00 is returned, it means parameters address is wrong. Please refer to below table:

For example, master writes 0x64 to F112. The command value of writing parameter is 2.
Parameter actual address is 0x010C. If response is failed, error code 0x01 is returned, it means
parameter value is wrong. Please refer to below table:
