PKW parameter area description
This data area is composed of ID, IND, VALUE_high and VALUE_low, as shown in
figure below. They are used to read or modify the parameter of a parameter of a
frequency converter, but only one parameter can be read or modified each time.
When master sends request and slave responds, bit definition for each specific
word in PKW area is shown in the tables below. If a frequency converter fails to
execute PKW area request command, an error code will be returned to the mas-
ter in VALUE_low. Refer to
