Write request: Assign digital input 2 with the function ON/OFF1 (p0840[1] = 722.2)
In order to link digital input 2 with ON/OFF1, you must assign parameter p0840[1] (source,
ON/OFF1) the value 722.2 (DI 2). To do this, you must populate the telegram of the
parameter channel as follows:
PKE, bit 12 … 15 (AK): = 7 hex
(change parameter value (field, word))
PKE, bit 0 … 10 (PNU): = 348 hex
(840 = 348 hex, no offset, as 840 < 1999)
IND, bit 815 (subindex): = 1 hex
(CDS1 = Index 1)
IND, bit 07 (page index): = 0 hex
(offset 0
corresponds to 0 hex)
PWE1, Bit 0 … 15
: =
2D2 hex
(722 = 2D2 hex)
PWE2, Bit 1015: = 3F hex
(drive object - for SINAMICS G120, always 63 = 3f hex)
PWE2, Bit 09: = 2 hex
(Index of Parameter (DI 2 = 2))
