4.4.1 PKE (Word 1)
PNU (PKE bit0 ~ bit10): Basic parameter number
Basic parameter number (PNU) = Address of AC motor drive to be polled – n*2,000 (n = PNU page
number). Range of PNU: 1 ~ 1,999 (decimal). PNU page number = 0, when the parameter address of
AC motor drive < 1,999 (decimal). When the parameter address of AC motor drive > 1,999 (decimal),
you will need to set up adequate PNU page number to make PNU < 1,999 (decimal).
SPM (PKE bit11): Reserved (Default = 0)

4.4.2 IND (Word 2)
See Table 1.4-5 for the data form of IND (sub-index of parameter). IND bit12 ~ bit15 are for page number
selection (see Table 1.4-6 for the definition of each bit). When you use PKW to poll the AC motor drive
parameters, you have to first make sure the page number. The value of page number is decided by bit12
~ bit15 of IND, which is the sum of each bit value multiplied by power value. For example, if the page
number is 4, bit12 ~ bit15 of IND will be 0100. After the page number is set, the IND value will be
confirmed as well. The IND value can be obtained by the binary bit0 ~ bit15 values. For example, if the
page number is 4, the IND value will be 2000 (hex).
