Telegram Examples, Length Of The Parameter Channel = 4 - Siemens SINAMICS G110M Function Manual

Parameter contents
Parameter contents can be parameter values or connector parameters. You require two
words for connector parameters. You can find more information on interconnecting
connector parameters in the operating instructions of the Control Unit in the section
"Interconnecting signals in the inverter".
Enter the parameter value in the parameter channel right-justified as follows:
• 8-bit values:
• 16-bit values: Low word, bits 0 ... 15,
• 32-bit values: Low word and high word
Enter a connector parameter right-justified as follows:
• Number of the connector parameter:
• Drive object of the connector parameter:
• The index or bit field number of the connector parameter:
5.3.4.1

Read request: Read out serial number of the Power Module (p7841[2])
To obtain the value of the indexed parameter p7841, you must fill the telegram of the
parameter channel with the following data:
● PKE, bit 12 ... 15 (AK): = 6 (request parameter value (field))
● PKE, bit 0 ... 10 (PNU): = 1841 (Parameter number without offset)
Parameter number = PNU + offset (page index)
(7841 = 1841 + 6000)
● IND, bit 8 ... 15 (page index): = 90 hex (offset 6000 ≙ 90 hex)
● IND, bit 0 ... 7 (subindex): = 2 (Index of the parameter)
● Because you want to read the parameter value, words 3 and 4 in the parameter channel
for requesting the parameter value are irrelevant. They should be assigned a value of 0,
for example.
