Parameter ID (PKE)
NOTE
Siemens AG 6SE7087-6NX84-0GB0
SIMOVERT MASTERDRIVES
With the PKW mechanism, you can perform the following tasks:
♦ reading parameters
♦ writing parameters
♦ reading the parameter description
(parameter type, max./min. value, etc.)
The parameter area is always composed of 4 words.
1st word
Byte 1
Bit No.: 15
AK
2nd word
Byte 3
Bit No.: 15
3rd word:
Byte 5
Parameter value Low (PWE1)
4th word:
Byte 7
Parameter value High (PWE2)
AK: Task or reply ID
SPM: Toggle bit for processing the parameter change report (not supported
by the CBL)
PNU: Parameter number
The parameter ID (PKE) is always a 16-bit value.
Bits 0 to 10 (PNU) contain the number of the required parameter. The
meaning of the parameters can be found in the section, "Parameter
list", of the converter operating instructions.
Bit 11 (SPM) is the toggle bit for parameter change reports.
Parameter change reports are not supported by the CBL.
Bits 12 to 15 (AK) contain the task reply ID.
The meaning of the task ID for the task telegram (master → converter)
is shown in Table 4-4. It corresponds to the specifications in the
"PROFIBUS profile for variable-speed drives". Task IDs 10 to 15 are
specific to SIMOVERT MASTERDRIVES and are not defined in the
PROFIBUS profile.
The meaning of the reply ID for the reply telegram (converter →
master) is shown in Table 4-5. This also corresponds to the
specifications in the "PROFIBUS profile for variable-speed drives".
