Example
The parameter 'PKW number' for the G-SST1 (number of net data in
the PKW channel):
Minimum value:
Maximum value:
Permissible values for USS:
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.
Parameter index
The index is an 8-bit value and is placed in bits 0 to 7. The bits 8 to 15
(IND) 2nd word
have additional features. Refer to instruction manual of the converter.
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).
Example
Source for the ON/OFF1 command (control word 1, bit 0):
Parameter index
P554 (=22A Hex)
Change parameter value of index 1.
2nd word
Bit No.:
Binary value
HEX value
Bits 8 to 15:
Bits 0 to 7:
Parameter value
The parameter value (PWE) is always transferred as a double word (32
(PWE) 3rd and 4th
bits). Only one parameter value at a time can be transferred in one
word
telegram.
A 32-bit parameter value is composed of PWE1 (least significant word,
3rd word) and PWE2 (most significant word, 4th word).
A 16 bit parameter value is transferred in PWE1 (least significant word,
3rd word). In this case, you must set PWE2 (most significant word, 4th
word) to the value 0.
