The parameter ‘PKW number’ for the G-SST1 (number of net data in
the PKW channel):
Minimum value: 0 (0 words)
Maximum value: 127 (corresponds to variable length)
Permissible values for USS: 0, 3, 4 and 127
If a change task with a PWE other than 0, 3, 4 or 127 is sent to the
converter, the reply is: 'Task cannot be executed' with error value 104.
The index is an 8-bit word and is always transferred over the CAN bus
in the low byte (bits 0 to 7) of the parameter index (IND). The high byte
(bits 8 to 15) of the parameter index (IND) contains the parameter page
selection bit (bit 15).
The parameter page selection bit acts as follows:
If this bit = 1, the parameter number (PNU) transferred in the PKW
request is given an offset of 2000 in the CBP and then passed on.

Parameter page selection
In the case of an indexed parameter, the required index is transferred.
The meaning of the indices can be found in the section, "Parameter
list", of the instruction manual for the converter.
In the case of a descriptive element, the number of the required
element is transferred. The meaning of the descriptive elements can be
found in the "PROFIBUS profile for variable-speed drives" (VDI/VDE
3689).
