Figure 5-35 IND structure (cyclic)
● The field sub-index is an 8 bit value which, in cyclic data transfer mode, is transferred in
the more-significant byte (bits 8 to 15) of the parameter index (IND).
● In this case, the least-significant byte (bits 0 to 7) in the parameter index selects the
parameter page for additional parameters.
Rules for the parameter range
The bit for selecting the parameter page functions as follows:
When it is set to 1, an offset of 2000 is applied in the inverter to the parameter number
(PNU) transferred in the parameter channel request before the data is transferred.
